ALLPOWERS P1800 1024Wh Review

1,024Wh of storage, 1,800W continuous output, LiFePO4 cells. Listed at $419 at ALLPOWERS.

The ALLPOWERS P1800 1024Wh is a portable 600 1,200wh unit holding 1,024Wh. At $0.41 per watt-hour it is priced below the median for the band, which makes it one of the cheaper ways to buy this much capacity. It uses LiFePO4 cells rated for 3,000 cycles, so it is built to be kept rather than replaced. It lists at $419 against an $1,059.98 MSRP.

What the ALLPOWERS P1800 1024Wh will run, and for how long

Runtimes below are calculated from the 1,024Wh rated capacity, derated to 85% for AC loads and 92% for USB and 12V loads to cover inverter and conversion losses. They are arithmetic, not lab measurements, but they are the same arithmetic applied to every unit we track, so the comparison holds. Anything drawing more than the 1,800W continuous rating is left off the list because this unit cannot carry it, though the 3,600W surge rating covers brief startup spikes from motors and compressors.

LoadEstimated runtime
Phone charge (12Wh)78 charges
Wi-Fi router (10W)87 hr
LED work light (10W)94 hr
CPAP, humidifier off (40W)21 hr 46 min
Laptop (60W)14 hr 30 min
12V portable fridge (45W avg)19 hr 21 min
55-inch TV (90W)9 hr 40 min

Real figures land below these. A fridge cycles rather than drawing continuously, and cold weather costs a lithium pack usable capacity, so treat the table as the ceiling rather than the expectation.

Charging and power delivery

Maximum solar input is 650W. At 70% of that rating, which is what a fixed panel realistically delivers across a good day, a full charge from empty is roughly 2 hr 15 min of usable sun. Switchover to battery is rated at 10ms, fast enough to keep a desktop or a router from dropping.

Where the ALLPOWERS P1800 1024Wh sits in its band

We track 57 units in the portable 600 1,200wh band with both a price and a published capacity. They run from $179 to $3,449, and from 99Wh to 5,040Wh. On cost per watt-hour the ALLPOWERS P1800 1024Wh ranks 10 of 57, where 1 is the cheapest capacity in the band. That puts it in the cheapest third, which is the single strongest thing on its spec sheet. Ranking on cost per watt-hour deliberately ignores build quality, port selection and warranty, so read it as one input rather than as the answer.

Alternatives to the ALLPOWERS P1800 1024Wh

Units we track in the same band that are close enough to be genuine substitutes, matched on capacity. Each links to its own review.

Who the ALLPOWERS P1800 1024Wh suits

It is a sensible buy for van and car camping, a long weekend off-grid, and covering a fridge plus lighting and devices through a day-long outage. It is the wrong tool for whole-home backup, and sustained use of a microwave or a kettle.

ALLPOWERS P1800 1024Wh questions

How long will the ALLPOWERS P1800 1024Wh run a fridge?

A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 1,024Wh, derated to 85% for inverter losses, that is roughly 17 hr 24 min on a full charge. A 12V portable fridge draws less and will run considerably longer.

Can the ALLPOWERS P1800 1024Wh be charged by solar?

Yes. It accepts up to 650W of solar input. Panels rarely hit their rated figure in the field, so plan on about 70% of the panel rating across a clear day.

Does the ALLPOWERS P1800 1024Wh work as a UPS?

It switches to battery in about 10ms. That is quick enough for a desktop computer, a router or a modem, all of which tolerate a gap in that range without rebooting.

What warranty does the ALLPOWERS P1800 1024Wh carry?

ALLPOWERS covers it for 5 years, and rates the cells for 3,000 charge cycles. Cycle life and warranty are different promises, and the cycle figure is the one that tells you how long the pack stays useful.

Is the ALLPOWERS P1800 1024Wh worth it?

At $419 it works out at $0.41 per watt-hour. It costs less per watt-hour than the median unit in its band, which is the strongest argument in its favour. Read the comparison table above against the two closest rivals before deciding.

What is not published

ALLPOWERS does not state the weight for this model. We list figures rather than estimate them, so those rows stay empty until the manufacturer publishes them. If you need one of them to make the decision, ask ALLPOWERS directly and hold them to the answer.

How we assess these

Every figure on this page comes from the manufacturer, and every derived number, cost per watt-hour and estimated runtime, is calculated the same way for all 437 products we track. That is what makes the comparison meaningful: we are not scoring units against a private impression of them, we are putting published figures side by side and doing the arithmetic in public. Where a manufacturer stays quiet, we say so rather than filling the gap.
