BLUETTI Apex 300 + 2×B500K
Thirteen kilowatt-hours at 282 pounds: the Apex 300 with two B500Ks is the top of the stack, a battery you give an address rather than carry. Every scene we run clears, the van day on under half; 10 of 21 head-to-heads. No owner has written in; reviewers praise the modular idea, then price the hub and the batteries.

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.

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.

Owner reports are paraphrased from public YouTube comments and each links to its source; reviewer consensus is counted from cited excerpts, never quoted; our own verdicts are quoted. Specs on this page never come from any of them.
Reviewer consensus
3/13 positive excerpts, 6 sources
Reviewers consistently note the lack of built-in USB/DC ports, requiring a separate $300 Hub D1 accessory, as a notable and costly design compromise.

From the test desk
“Take the Apex 300 stack.”
“Buy the Apex 300 + 2×B500K unless you have a load above 3,840 watts.”
“Buy the Elite 300 unless you can already name a load over roughly 3,000Wh a day.”

Questions people ask
Is the Apex 300 + 2×B500K really about 8 times heavier than the AC180P?
Yes — 282.2 lbs against 35.3 lbs, which works out to almost exactly eight times the weight. It's built to be installed once and left in place, not carried around, and reviewers describe needing both hands to move the base unit at all [B4].
Why is the Apex 300 + 2×B500K cheaper per kWh if it costs so much more overall?
Because sticker price and per-unit-energy cost are different questions. The Apex 300 stack runs $0.38 per Wh and $0.11 per lifetime kWh against the AC180P's $0.45 per Wh and $0.13 per lifetime kWh — a better rate on paper. But you're still writing a check for $5,399 versus $649, and that $4,350 gap only makes sense once you actually need the extra 11,565Wh.
Can the Bluetti Apex 300 + 2×B500K run a whole house during an outage?
Not for heavy circuits. Its 3,840W continuous output and 7,680W surge ceiling can handle lighter loads — lights, a fridge, electronics — but a 5-ton central AC or an electric range typically surges past that ceiling. The DELTA Pro Ultra X's 12,000W output and 45,000W surge are built specifically for whole-panel backup.
Is the Bluetti Apex 300 + 2×B500K actually cheaper than the Goal Zero Yeti PRO 8000?
Yes — by $600, and it holds 5,016.8Wh more capacity on top of that. At a blended $0.38/Wh against the Yeti's $0.75/Wh, it isn't a premium purchase at all; it's the cheaper option with more capacity. The Yeti's real remaining case is the extra 86.25 lbs it saves and its higher rated cycle count, not price.

Can the Anker S5000 expand to match the Apex 300 + 2×B500K?
Yes. It takes up to five BP5000 packs of 5,024Wh each [A6], and two of them bring it to 15,072Wh, more than the BLUETTI stack's 13,004.8Wh. Our record has no BP5000 price yet, so we can't compare the total cost.
