BLUETTI EP500Pro
The EP500Pro is five kilowatt-hours that cannot grow and barely moves: 187 pounds on wheels, which reviewers say takes two people and a staircase to appreciate. It clears every scene but the van day; three of eight head-to-heads won, two Goal Zero. No owner has written in; testers say it holds its charge through a year in storage.

What the EP500Pro actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

03 · From the verdicts
Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the EP500Pro if…
You value a proven track record over specs — a documented 1.5-year field record the new stack can't match yet [B1].
Decided 2 matchups · read one →
You want one sealed, integrated box with a quiet fan and no cables to add [B6] — simplicity over expandability.
Your loads are modest and fixed — 3,000W and 5,120Wh comfortably cover a fridge, lights, and electronics with no plans to scale up.
Buyers who want one integrated wheeled cabinet instead of a two-box stack they assemble [A5].
A rival won when…
You want the most capability for the money — 5,530Wh, 5,000W continuous, and a 10,000W surge for $200 less.
Decided 3 matchups · read one →
Anyone who wants room to grow. The Apex starts at 5,530Wh and takes B300K expansion batteries; the EP500Pro is sealed at 5,120Wh.
Decided 3 matchups · read one →
Your needs might grow — the AC500 expands past 5,530Wh; the EP500Pro never will.
You run a full off-grid day — the AC500 clears about 4,685Wh on one charge where the sealed EP500Pro comes up short.

How to read this
- Usual is the price the unit carried most of the time, tested for how long it held rather than how often we looked. A weekend promotion cannot move it.
- Best is the lowest price we have read on the store itself. Typed coupon codes, member-only prices and marketplace listings are not counted; anything applied automatically at checkout is.
- A gap in the line is a day we could not read a price. We never draw across one, and we never show the store’s own “was” price.

Reviewer consensus
5/11 positive excerpts, 5 sources
Reviewers repeatedly flag the EP500 Pro's 180+ lb weight as making it essentially immovable without its wheels, needing two people to shift it upstairs.

From the test desk
“Take the Apex 300.”
“The AC500 + 2*B300K beats the EP500Pro on price and nearly every capability that matters.”
“Take the Apex 300 + B300K unless you specifically want one sealed, proven cabinet.”

Questions people ask
Is the EP500Pro worth double the price of the Apex 300?
Only if you regularly drain past the Apex's 2,350Wh of usable energy. The $1,800 step up buys 2,355Wh, a worse rate per watt-hour than either unit charges across its own pack, and it buys no extra service life since both are rated 3,500 cycles. Below that draw you're paying a premium for a reserve you'll never touch.
Can I expand the Apex 300 to match the EP500Pro's capacity?
It accepts BLUETTI expansion batteries, so its capacity isn't fixed the way the EP500Pro's 5,120Wh is. Be clear-eyed about the value, though: the Apex starts at 2,765Wh, so the first expansion battery mostly buys back capacity the EP500Pro ships with. Expansion earns its keep when your target sits above 5,120Wh, not below it.
Is the EP500Pro too heavy to move?
For one person, yes. It's 187 lbs on wheels, and reviewers describe two fit people struggling to get it upstairs [B7][B11]. Treat it as an appliance you install rather than a power station you carry, and pick its spot before delivery. The Apex at 84 lbs is still a bent-knees, two-hands lift, but it is a lift.
BLUETTI AC500 + 2*B300K or EP500Pro — which should I buy?
The AC500 + 2*B300K for most people. It costs $200 less, holds 410Wh more, runs 2,000W more continuous output, and can expand where the EP500Pro is sealed for life. Choose the EP500Pro only if a proven, integrated design with a documented long-term record matters more to you than capability or price [B1].
Is the EP500Pro's fixed capacity actually a problem?
It can be. At 5,120Wh sealed, it covers everyday backup fine, but it can't be expanded and it comes up short on a full off-grid day of about 4,685Wh. The AC500 starts higher at 5,530Wh and adds batteries, so its ceiling moves with your needs while the EP500Pro's stays put.
