ALLWEI PPS600-1 Power Station (512Wh) — read reviewA 512Wh LiFePO4 power station with 500W AC output and a 1000W peak, listed from $329 and 13.9 lbs (6.3 kg) in its spec block. It suits small camping, RV and backup loads, with a 100W solar kit option at $529.
A portable power station is a battery with an inverter built in, so two numbers matter and they are not the same thing. Watt-hours (Wh) say how much energy it stores; watts (W) say how much it can deliver at once. The three ALLWEI stations here list 256Wh with 300W of AC output, 512Wh with 500W and 2048Wh with 2400W, at prices from $179, $329 and $879 as listed on October 23, 2026. Check first that the AC watts cover the largest device you would plug in, then divide the watt-hours by that device's watts for a rough number of hours. All three list pure sine wave AC, which follows the smooth waveform of grid power, and each gives a peak or surge rating, 600W, 1000W and 4800W, for a short start-up burst.
Weights run from 6.5 lb to about 51.8 lb. Only the two larger stations name a battery type: the 512Wh PPS600-1 and the 2048Wh PPS2400 list LiFePO4, short for lithium iron phosphate, while the 256Wh page says only 'quality lithium batteries'. Capacity and cycle-life figures are ALLWEI's own, and they disagree. The PPS600-1 gives 3000 cycles to 70% of capacity in its copy and 2000 times at 80% or more depth of discharge in its spec block; the PPS2400 gives 3500 cycles to 70% or more. Recharge figures differ in kind: the 256Wh lists AC in 3.5 to 4 hours, the PPS600-1 lists input watts only, and the PPS2400 lists 1.5 to 2 hours in its fastest mode against about 1.3 hours in its copy.
All three are sold by ALLWEI at allweipower.com. Shipping is free by ground carrier in the contiguous US only, with orders shipping in 1 to 2 business days and arriving in 3 to 7. The policy rules out air shipping because of the lithium batteries, yet the PPS2400 page promises complimentary express shipping. Returns run 30 days from receipt for an unused unit in its original packaging with every accessory and an RMA number from support; you pay return shipping unless it is a quality issue. A separate 90-day exchange-only policy names the PPS300, PPS600, PPS1200, PPS2400 and B200 Pro. The warranty page lists 2 years plus 1 more with registration for the PPS600-1 and 3 plus 3 for the PPS2400, but its table labels the extra years 'Paid'. It does not name the 256Wh unit by its title, so ask which period applies.
Look elsewhere if you need pages that agree with themselves. The PPS600-1 counts 2 AC outlets in its copy and 3 in its spec block, and the PPS2400 gives no count. The PPS2400's solar input is 1200W in its copy and 500W Max in its FAQ, so ask which applies before buying a solar kit. On the 256Wh page the capacity row pairs 256Wh with 26Ah at 10.8V, the same Ah and voltage the store's separate PPS300 page gives for 280Wh. An Amazon affiliate review lists a 3600W surge and a 5-year warranty for the PPS2400, against the store's 4800W and 3+3 years. We found no independent lab test of any ALLWEI station.
| Review | Price | Capacity | AC output | Weight | Recharge |
|---|---|---|---|---|---|
| ALLWEI PPS2400 Power Station (2048Wh) | From $879 | 2048Wh LiFePO4, 3500 cycles to 70%+ capacity per the page | 2400W continuous, 4800W surge peak at 0.2 seconds, pure sine wave | About 51.8 lbs (23.5 kg) | AC 0 to 80% in 60 minutes per the copy; solar given as both 1200W and 500W Max |
| ALLWEI 300W / 256Wh Power Station | From $179 | 256Wh in the title and spec block; the page says only 'quality lithium batteries' | 300W Max continuous, 600W peak, pure sine wave, 1 US AC outlet | 6.5 LBS in the spec block; 6.4 lbs in the copy | AC 3.5 to 4 hours (57W external charger), car 3 to 3.5 hours, 100W solar 3.5 to 4 hours |
| ALLWEI PPS600-1 Power Station (512Wh) | From $329 | LiFePO4 512Wh +/-5% (20Ah/25.6V) | 500W with a 1000W peak, pure sine wave; 3 outlets in the spec block, 2 in the copy | 6.3kg/13.9lbs in the spec block; 13 lbs in the copy | AC 200W Max, car 120W Max, solar 120W Max (DC12V to 24V) |
Watts (W) measure power, how much a station can supply at one moment: the AC outputs here are 300W, 500W and 2400W. Watt-hours (Wh) measure stored energy: 256Wh, 512Wh and 2048Wh. Divide a station's watt-hours by a device's watts for a rough number of hours. None of these pages gives run times for any device, and the capacity figures are the store's own.
Start from the watts of the largest device you will plug in, which must stay under the station's continuous AC output, then the hours you want. The 256Wh unit lists one US AC outlet at 300W and says it is not suitable for jump-starting a car battery. The PPS600-1 lists 500W and the PPS2400 2400W; the PPS2400 page adds that up to 4 B200 PRO expansion batteries can raise capacity to 10240Wh.
It is short for lithium iron phosphate, a lithium battery chemistry. The 512Wh PPS600-1 and 2048Wh PPS2400 pages list it; the 256Wh page says only 'quality lithium batteries'. Cycle life is the store's own figure: 3500 cycles to 70% or more of capacity on the PPS2400, and on the PPS600-1 3000 cycles to 70% in its copy but 2000 times at 80% or more depth of discharge in its spec block.
The pages give different figures. The 256Wh unit lists AC in 3.5 to 4 hours with a 57W external charger, car in 3 to 3.5 hours and a 100W solar panel in 3.5 to 4 hours, while the store's separate 280Wh PPS300 page lists 5.5 to 6.5 hours with the same charger. The PPS600-1 lists maximum input watts only: AC 200W, car 120W, solar 120W. The PPS2400 lists AC modes of 6 to 7, 4 to 5 and 1.5 to 2 hours, and car charging of 19 to 21 hours at 12V or 3 to 4 hours at 24V.
All three are sold with solar options, but the limits are thin. The 256Wh unit costs from $179 alone or $359 with a 100W panel, and its spec block has no solar input row. The PPS600-1 takes up to 120W of solar and costs $529 with a 100W kit. The PPS2400 comes in five options from $879 to $1,679, four with 200W or 400W kits, and its page gives solar input as 1200W in the copy and 500W Max in the FAQ.
Ground shipping is free in the contiguous US, 3 to 7 business days after 1 to 2 days to ship. Returns run 30 days from receipt, unused and in the original packaging, with an RMA number; you pay return shipping unless it is a quality issue. Cancelling after an order ships costs round-trip shipping plus a 2.6% card fee. The warranty is 2 years plus 1 with registration on the PPS600-1 and 3 plus 3 on the PPS2400, the extra years marked 'Paid' in its table.
