Anker SOLIX PowerHouse 522 Review
299Wh of storage, 300W continuous output, LiFePO4 cells. Listed at $118 at Anker SOLIX.
The Anker SOLIX PowerHouse 522 is a portable under 600wh unit holding 299Wh. At $0.39 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, so it is built to be kept rather than replaced.

What the Anker SOLIX PowerHouse 522 will run, and for how long
Runtimes below are calculated from the 299Wh 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 300W continuous rating is left off the list because this unit cannot carry it.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 22 charges |
| Wi-Fi router (10W) | 25 hr |
| LED work light (10W) | 28 hr |
| CPAP, humidifier off (40W) | 6 hr 21 min |
| Laptop (60W) | 4 hr 14 min |
| 12V portable fridge (45W avg) | 5 hr 39 min |
| 55-inch TV (90W) | 2 hr 49 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.

Where the Anker SOLIX PowerHouse 522 sits in its band
We track 36 units in the portable under 600wh band with both a price and a published capacity. They run from $118 to $599.95, and from 128Wh to 576Wh. On cost per watt-hour the Anker SOLIX PowerHouse 522 ranks 2 of 36, 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 Anker SOLIX PowerHouse 522

Who the Anker SOLIX PowerHouse 522 suits
It is a sensible buy for weekend camping, a CPAP overnight, phones and laptops, and keeping a router alive through a short outage. It is the wrong tool for anything with a heating element, and any attempt to run a fridge for more than a day.
Anker SOLIX PowerHouse 522 questions
How long will the Anker SOLIX PowerHouse 522 run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 299Wh, derated to 85% for inverter losses, that is roughly 5 hr 5 min on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the Anker SOLIX PowerHouse 522 be charged by solar?
Anker SOLIX does not publish a maximum solar input for this model. Rather than estimate one, we leave it out. Check the manual that ships with the unit before buying panels for it.
Is the Anker SOLIX PowerHouse 522 worth it?
At $118 it works out at $0.39 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
Anker SOLIX does not state the rated cycle life, the weight, the maximum solar input, the warranty term 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 Anker SOLIX 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.
