Head-to-head test
BLUETTI AC50B vs Jackery Explorer 500
Jackery no longer sells the Explorer 500, and the AC50B, the one you can still buy, is also the one with the UPS mode, the USB-C ports, twice the solar input and nearly four times the rated cycles.

Spec deltas
Jackery no longer sells the Explorer 500, so of these two only the AC50B can still be bought, at $399. Jackery now points Explorer 500 shoppers to the HomePower 1000 v2, which is a step up in size rather than a like-for-like swap. If you came here to choose between these two boxes, the choice has been made for you. What's left is whether the AC50B deserves the slot, and whether an Explorer 500 you already own is worth replacing.
On the spec sheet, the AC50B earns it. It runs 700W continuous against 500W, carries two USB-C ports up to 65W where the Explorer 500 has none, takes 200W of solar against 100W, and can sit inline as a UPS that hands over in no more than 20ms. Under all of that is the pack: rated for 3,000 cycles against 800, which over rated life is 1,344 kWh delivered against 414.
The Explorer 500 kept three things. It holds 70Wh more, weighs 1.5 lbs less, and publishes a 1,000W surge rating where the AC50B publishes no headroom above its 700W. That last one is the real catch on our pick, and it only matters for a motor whose start-up spike climbs past 700W.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
At the cut, the AC50B is already inline and hands the router to battery in no more than 20ms; the Explorer 500 needs you to find it in the dark and move the plug. The next morning, 448Wh at 200W is a little over two hours of ideal sun, while 518Wh at 100W is more than five. When an outage runs into day two, the small battery that refills by lunch beats the slightly bigger one that refills by dusk.
AC50B: UPS switchover rated ≤20ms; Explorer 500: no UPS mode listedSolar input: AC50B 200W into 448Wh; Explorer 500 100W into 518Wh8-Hour Blackout needs 1,645Wh; AC50B usable 381Wh covers about 23%
Why it mattersIf the grid is your reason for owning one of these, the AC50B is the one with the features for that job.
Both units have exactly one AC outlet. On the Explorer 500 the laptop brick takes it, and the lamp or fan you wanted to run waits its turn. On the AC50B the laptop goes to USB-C and the outlet stays free, so the box with 70Wh less battery is the one that can power the whole desk at once.
AC50B: 2 USB-C ports, up to 65WExplorer 500: 0 USB-C ports, 3 USB-ABoth units: 1 AC outlet
Why it mattersIf a USB-C laptop is the main thing you're powering, the AC50B's ports matter more than the Explorer 500's extra 70Wh.
rated cycles
Nightly, the Explorer 500's 800 cycles are spent in about 2.2 years and the AC50B's 3,000 last about 8.2. An Explorer 500 that has run a CPAP since the day it was bought may already be near the end of its rating, and the AC50B is the buyable unit that still covers the night, with a margin thin enough that you shouldn't hang a second load on it.
CPAP Overnight needs 320Wh: AC50B left with 61Wh, Explorer 500 with 120WhRated cycles: AC50B 3,000, Explorer 500 800At daily use: AC50B 8.2 years, Explorer 500 2.2 years
Why it mattersExplorer 500 owners on nightly CPAP duty have a real reason to replace; weekend users mostly don't.
continuous output
Power Lifting doesn't close that gap. It lets a heater or kettle rated up to 1,000W run more slowly, and it does nothing for a compressor or a pump. Anything that starts within 700W sits inside the AC50B's continuous rating; a motor whose start-up spike climbs past that is unproven on its spec sheet rather than ruled out.
Explorer 500: 500W continuous, 1,000W published surgeAC50B: 700W continuous, no published surge headroomAC50B Power Lifting: resistive loads up to 1,000W, run at reduced power
Why it mattersIf your Explorer 500 starts a small fridge or pump today, test that load on an AC50B inside its return window, because the spec sheet won't settle it.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: the AC50B's ≤20ms UPS mode, 65W USB-C ports and 200W solar input are things the Explorer 500 doesn't offer, and none of them show up in a capacity column.
rated cycles
One card decides whether either of these is a backup unit. The AC50B lists a UPS mode: leave it on the wall with the router and modem plugged in, and when the grid drops it switches to battery in no more than 20ms, which routers and most electronics ride through and the fussiest desktop PC power supplies sit right at. The Explorer 500 lists no UPS mode. You plug into it after the lights are already out.
Ports and panels go the same way: two USB-C ports up to 65W against none, 200W of solar against 100W, and a phone app with low-battery alerts where the Explorer 500 has a front panel and nothing else. The one card facing the other way is noise. BLUETTI rates the AC50B at 45 dB and Jackery rates the Explorer 500 at 37, but each maker publishes its own way, so treat the gap as a reason to look for hands-on reports, not a difference you can count on hearing.
Your Life, Your Pick
Selected because: five of six scenarios come back neither, and the one the Explorer 500 wins, CPAP Overnight, is the nightly duty that runs down its 800-cycle rating fastest.
Five of the six scenarios come back neither, and for anyone shopping these as home backup that's the most useful line on the page. The closest miss is the tailgate: 670Wh needed, with the AC50B covering about 57% and the Explorer 500 about 66%, so you plan the day around them rather than rule them out. The rest, from a 910Wh remote workday to a 4,685Wh van day, aren't close.
CPAP Overnight goes to the Explorer 500 on margin, 120Wh left after a 320Wh night against the AC50B's 61Wh. That's a fair win on paper, held by a unit Jackery no longer sells, on the nightly duty that spends an 800-cycle rating in about 2.2 years. The AC50B covers the same night once, with too little left over to add a second load.
Runtime: Will It Power Your Gear?
Selected because: the Explorer 500 holds 70Wh more but runs 500W continuous against the AC50B's 700W, so they split on what each can run more than on how long.
continuous output
Run a CPAP's 40W off each and the size difference comes into focus: 381 usable watt-hours on the AC50B is about 9.5 hours, and 440 on the Explorer 500 is about 11. One night each. These are single-load boxes, and the 70Wh between them changes how long, not what.
What they can run is where they split. Anything drawing between 500W and 700W runs on the AC50B and overloads the Explorer 500. Going the other way, the Explorer 500 publishes 1,000W of surge for a motor's start-up and the AC50B publishes nothing above its 700W; its Power Lifting mode runs resistive loads up to 1,000W at reduced power and does nothing for a compressor. The AC50B is the stronger box all day. The Explorer 500 is the one with a promise on paper for the start-up.
Lifetime Value
Selected because: 3,000 rated cycles against 800 is 1,344 kWh of rated lifetime energy against 414, and that gap matters most to anyone who already owns the retired unit.
Rated 3,000 cycles against 800, the AC50B is good for 1,344 kWh over its rated life and the Explorer 500 for 414: more than three times the energy, out of a pack 70Wh smaller. The Explorer 500's traditional lithium-ion cells are the reasonB1B4, against the AC50B's LiFePO4 packA1.
For an Explorer 500 owner, the question is where you sit on that clock. A weekend at a time, 800 cycles is about 7.7 years from new and probably not your problem yet. Every night, it's about 2.2 years, and if you've had yours that long, the AC50B's 8.2 years of nightly rating is the case for replacing it.
Brand Trust
Selected because: BLUETTI's inconsistent support is the AC50B's one real risk, and buying direct is also what earns its full warranty term.
The AC50B's one real dent is BLUETTI's support, the most inconsistent in the category: email-based, on China time, with outcomes that range from a quick fix to weeks of back-and-forth or a discount on a new unit instead of a repair. Buying direct from BLUETTI improves the odds, and it's also how the AC50B gets its full term of up to 5 years, since reseller purchases carry less. BLUETTI keeps no spare-parts policy for some older and discontinued models, so treat this sealed box as one you'll use up rather than one you'll fix.
Jackery's strength was always the store, not the support desk: Costco, Home Depot, Best Buy and Amazon, and a return counter you can drive to. That still holds, just not for this unit. With the Explorer 500 gone, staying with Jackery means the HomePower 1000 v2, a bigger purchase in a different class; choosing the AC50B means accepting BLUETTI's support in exchange for the better small box.

Neither unit
Neither unit covers this scenario's 2,100Wh: the AC50B comes up 1,719Wh short (about 18% covered), the Explorer 500 1,660Wh (21%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither. The modeled evening needs 1,645Wh; the AC50B's usable 381Wh covers about 23% of it and the Explorer 500's 440Wh about 27%. The split comes at the moment the power goes: the AC50B, left inline, hands the router to battery in no more than 20ms, while the Explorer 500 lists no UPS mode, so the router reboots and waits for you to find a flashlight.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
The Explorer 500 wins this row on margin. A 40W machine over eight hours is 320Wh, which leaves it 120Wh spare against the AC50B's 61Wh. That's one night each, not several. The two noise ratings are each maker's own, published differently, so neither says what a 40W draw sounds like at the pillow. The catch is that Jackery no longer sells the Explorer 500, and nightly use is exactly what spends its 800-cycle rating fastest.

Conclusion
October 11, 2026
Verdict: the BLUETTI AC50B
Buy the AC50B. It's the only one of the two still on sale, and it would win this page anyway: 700W continuous against 500W, a UPS mode rated to switch in no more than 20ms where the Explorer 500 lists none, two USB-C ports up to 65W against none, 200W of solar input against 100W, up to 5 years of warranty with registration against 2, and 3,000 rated cycles against 800. The Explorer 500's edges are 70Wh more battery, 1.5 lbs less weight and a published 1,000W surge rating, and none of them can be bought new. If you already own a healthy Explorer 500 that comes out on weekends, keep it. If it runs a CPAP every night, its rating is spent in about 2.2 years of nights, and the AC50B is the replacement that still covers one.

See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, AC50B rates 4.6/5 (79th percentile of 25 Personal-class units), and Explorer 500 rates 3.3/5 (1st percentile of 20 Compact-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
AC50B: 45dB Published
45dB is about as loud as a running refrigerator. The Explorer 500 is rated 37dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Explorer 500: Solar Recharge Takes 5.2h+
At its 100W rated solar ceiling, refilling the full 518Wh takes about 5.2 hours of sun — as a floor, since the rated figure assumes ideal panel angle and clear sky, and real days deliver less. Not practical as the primary charge source for daily off-grid use; treat solar as a top-up and plan on a wall outlet or generator.
Explorer 500: No App Control
Without app control, you have to physically walk to the Explorer 500 to check battery level, adjust settings, or monitor power draw. The AC50B lets you do all that from your phone, including getting low-battery alerts.
AC50B: Power Lifting to 1,000W
The AC50B has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 1,000W from its 700W inverter. It does that by delivering less power than the appliance asks for, not more than the inverter has: the heater still works, it just heats more slowly. Two things follow. BLUETTI scopes the mode to purely resistive loads — a heater, a kettle, an incandescent lamp — so it does nothing for a fridge compressor, a pump or a power tool, and this record publishes no surge figure at all, so read the mode as a resistive-load feature rather than as starting ability. And it is not a reason to size down, because running a load that big from 448Wh is a short session either way. Genuinely useful if a heater or a kettle is why you're buying; beside the point otherwise. The Explorer 500 publishes no equivalent.
Only the AC50B Lists a UPS Mode
The AC50B can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. Worth it for a router, a desktop PC, or a CPAP. The Explorer 500's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Up to 5 years against 2
The AC50B carries up to 5 years, with registration or when bought direct from BLUETTI; reseller purchases carry a shorter term, so where you buy it decides how much cover you get. The Explorer 500's record carries 2 years, and Jackery no longer sells it, so its cover only matters to an owner who bought one recently. On a battery you plan to keep for years, the longer term on the buyable unit is the one that counts.
Battery Lifespan in Real Years
The AC50B is rated for 3,000 cycles vs 800. In real life: at daily use, that's 8.2 vs 2.2 years. At weekend use (twice a week), it's 29 vs 8 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
The Explorer 500 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the AC50B works out at $0.30/kWh over its rated life. If you already own the Explorer 500, the hardware comparison still holds: over its rated life the AC50B delivers about 1,344 kWh and the Explorer 500 about 414 kWh.
Brand trust
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
Jackery no longer sells the Explorer 500. It's one of the older models on NMC chemistry, rated for 800 cycles, which most of Jackery's current line has moved past by switching to LFP.
Analyst note
BLUETTI sells the better small box with a support desk you may have to chase; buying direct is the fix, and it's also how you get the full warranty term. Jackery's case was always the store, with a return counter at Costco, Home Depot, Best Buy or Amazon. That case now belongs to the HomePower 1000 v2, because the Explorer 500 has left Jackery's range. At this size, only one of these two brands is still selling you a unit.
Growth path

Analyst note
Growth only counts if you can still buy in, and the Explorer 500 is no longer sold (Jackery points owners to the HomePower 1000 v2). That leaves the AC50B: it is sealed at 448Wh, so buy the size that covers you now. The Explorer 500's fixed 518Wh still matters if you already own one, but it isn't a reason to pick it over the AC50B.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI AC50B
The AC50B's record is reviewer-deep and owner-thin: write-ups of new units and no long-term ownership history yetA1A2A3. They agree on the basics, a LiFePO4 pack with 700W output and BLUETTI's 1,000W Power Lifting modeA1, and on the carry: at 14.8 lbs it's well under BLUETTI's own AC70 at 21.4 lbsA2.
Wall charging draws the most attention: about 3 hours on the standard charger, 0 to 80% in 45 minutes, and 1.25 hours with BLUETTI's optional 480W Turbo chargerA3. BLUETTI's own FAQ scopes its B80 battery to Power Bank Mode, which recharges the AC50B rather than extending it as one system, so treat it as sealed at 448WhA4A0. The cycle rating is a spec claim no reviewer has had time to testA1A3.

“At 14.8 lbs it's meaningfully lighter than the AC70 (21.4 lbs) — a genuinely portable sub-15-lb unit with a long-cycle battery and 700W output at an easy-to-justify price.”

“Standard AC charging is about 3 hours, dropping to 1.25 hours with the optional 480W Turbo charger; 0-80% in 45 minutes.”

“The B80 can add 806Wh, but BLUETTI scopes this to "capacity expansion with B80 battery in Power Bank Mode" over an Aviation-to-XT60 cable — the pack recharges the unit rather than extending it as one system, so this is not expandability in the sense this site uses. At $279 it is BLUETTI's most affordable LiFePO4 station.”

Who Should Buy Which
Buy the AC50B if you…
- →Your router and modem should ride through a grid cut without rebooting. The AC50B sits inline and hands over in no more than 20ms; the Explorer 500 lists no UPS mode at all.
- →Your workday runs on a USB-C laptop and a phone. Two USB-C ports up to 65W feed them directly and leave the single AC outlet free for a lamp or a fan.
- →You own an Explorer 500 that runs a CPAP every night. At that pace its 800-cycle rating lasts about 2.2 years; the AC50B covers the same 320Wh night with 61Wh to spare and is rated for about 8.2 years of nights.
- →You'll pair it with a panel. 200W of solar input refills 448Wh in a little over two hours of ideal sun, which turns an outage that runs into a second day into a chore rather than a countdown.
Buy the Explorer 500 if you…
- →No new buyer. Jackery no longer sells the Explorer 500; if you want to stay with Jackery, its pointer is the HomePower 1000 v2, a step up in size rather than a swap.
- →You already own one, it still holds a charge, and it comes out a weekend at a time. At that pace its 800 rated cycles stretch to about 7.7 years from new, and a battery you haven't worn out isn't a reason to spend money.
- →Your Explorer 500 already starts a motor load with a hard kick. Its published 1,000W surge is the one line on its sheet the AC50B doesn't match on paper, so keep it on that job until you've tested the load on a replacement.
If neither fits
Close both tabs if you're sizing this for the house. A modeled 8-hour blackout needs 1,645Wh; the AC50B's 381 usable watt-hours covers about 23% of it, the Explorer 500's 440 about 27%, and neither unit expands. An evening of real home backup means buying a larger station built for that job from the start, not stacking small boxes.
The Bottom Line
Buy the AC50B. The Explorer 500 has left Jackery's range, and it was the weaker box on paper anyway: less continuous output, no USB-C, half the solar input, no UPS mode, and a pack rated for 800 cycles against 3,000.
If you already own an Explorer 500 and it comes out on weekends, its rating has room at that pace; leave it alone. If it runs something every night, or you need the router to stay up through a cut, the AC50B is the replacement that does both. Go get the BLUETTI.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery Explorer 500 discontinued?
Yes. Jackery no longer sells the Explorer 500, and its product page now forwards to the HomePower 1000 v2. That's a step up in size rather than a like-for-like replacement, since nothing Jackery currently sells sits at the Explorer 500's size.
Is the BLUETTI AC50B better than the Jackery Explorer 500?
Yes, on nearly everything that decides a purchase. The AC50B runs 700W continuous against 500W, has two USB-C ports up to 65W where the Explorer 500 has none, takes twice the solar input, lists a UPS mode, and is rated for 3,000 cycles against 800. The Explorer 500 holds 70Wh more, weighs 1.5 lbs less and publishes a 1,000W surge rating the AC50B doesn't match on paper, and it's no longer sold.
Can the BLUETTI AC50B be used as a UPS?
Yes, with one caveat. It's rated to switch to battery in no more than 20ms, which suits routers, modems and most electronics, while the fussiest desktop PC power supplies sit right at that line. The Explorer 500 lists no UPS mode, so anything plugged into it only rides an outage after you move the plug.
Which is better for a CPAP, the AC50B or the Explorer 500?
The Explorer 500 finishes a 320Wh night with more left, 120Wh against 61Wh, but Jackery no longer sells it. The AC50B covers the night with a thin margin, and its 3,000-cycle rating works out to about 8.2 years of nightly use against the Explorer 500's 2.2. The two makers publish noise ratings in different ways, so look for hands-on reports before either one goes next to the bed.
Does the Jackery Explorer 500 have USB-C?
No. Its record lists three USB-A ports and no USB-C, so a USB-C laptop has to charge through its own wall brick from the single AC outlet. The AC50B has two USB-C ports with up to 65W, which charges a laptop directly and leaves its AC outlet free.
