BLUETTI Apex 300 + B300K
5.5 kilowatt-hours at 149 pounds stacked: the Apex 300 with one B300K clears every scene we run, the van day to the last watt-hour, nothing left for the reading lamp. It wins 22 of 33 head-to-heads. No owner has written in; reviewers say it replaces a generator, then the hub you still buy for a USB port.

What the Apex 300 + B300K 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.

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.

Will the BLUETTI Apex 300 + B300K go on sale for Black Friday?
Price to beat $2,599Nobody knows until BLUETTI moves, but in 80 days we have tracked it, it has never been discounted, so any real cut would be a first. We read the store twice a day, and the moment it drops it shows on our Black Friday deals page.

What owners and reviewers say
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
5/15 positive excerpts, 7 sources
Reviewers consistently flag that the base Apex 300 has no USB/DC ports and requires a separate paid Hub D1 accessory, which some feel is overpriced for what it offers.

From the test desk
“Both are the identical Apex 300 base — 3,840W continuous, 7,680W surge, 3,500 cycles, 2,400W of solar, a 10ms switchover — with only the battery changing.”
“Buy the Apex 300 + B300K if your daily draw looks like Van Life Daily's 4,685Wh — it's the only one of the two that gets through that day, using right around all of its usable capacity while the Elite 300 would need 183%…”
“The Apex 300 + B300K costs $1,200 more than the Elite 400 ($2,599 vs $1,399), but it wins on the two things that actually separate them: it's expandable and the Elite isn't, and it's cheaper to own per lifetime kWh at…”

Questions people ask
Can the Apex 300 + B300K actually get through a full day of van life?
Yes. Van Life Daily's 4,685Wh draw uses right around all of the Apex 300 + B300K's usable capacity, which is enough to cover it with the numbers as tested. The Elite 300 can't make the same claim here: the identical load would need 183% of what it actually holds, meaning it runs out with real hours of the day still left.
Does the Apex 300 + B300K come with USB and DC charging ports out of the box?
Not really. Reviewers report the base Apex 300 ships with six AC outlets and high-voltage connectors but no USB or DC ports at all [A1], and getting them means buying BLUETTI's separate Hub D1 accessory [A2]. Budget for that as part of the real purchase, not an optional add-on.
Which BLUETTI unit is cheaper to own over time, the Apex 300 + B300K or the Elite 300?
The Elite 300, clearly. It costs $0.07 per lifetime kilowatt-hour against the Apex 300 + B300K's $0.13, and its 5-year warranty works out to $240 a year of coverage against $520. The Apex 300 + B300K's higher price buys more capacity, not a better-built battery.
Can the BLUETTI Elite 400 be expanded like the Apex 300 + B300K?
No. The Elite 400 is a closed system fixed at 3,840Wh for the life of the unit, with no expansion battery available. The Apex 300 + B300K, by contrast, accepts a second B300K pack to add capacity without replacing the base unit — the single structural difference between these two same-brand units.
Is the Apex 300 + B300K worth $1,200 more than the Elite 400?
It depends on whether your power needs might grow. The Apex costs more up front but works out cheaper per lifetime kilowatt-hour ($0.13 vs $0.15) and can expand later; the Elite 400 is lighter, quieter, and cheaper on the sticker, but what you buy is what you'll always have.
