Anker SOLIX 555 PowerHouse Review
1,024Wh of storage, 1,000W continuous output, LiFePO4 cells. Listed at $899.99 at Anker SOLIX.
The Anker SOLIX 555 PowerHouse is a portable 600 1,200wh unit holding 1,024Wh. At $0.88 per watt-hour it is priced above the median for the band, so you are paying a premium over comparable capacity. It uses LiFePO4 cells, so it is built to be kept rather than replaced. This model is discontinued, so stock is whatever is left in the channel.

What the Anker SOLIX 555 PowerHouse 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 1,000W continuous rating is left off the list because this unit cannot carry it.
| Load | Estimated 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 200W. At 70% of that rating, which is what a fixed panel realistically delivers across a good day, a full charge from empty is roughly 7 hr 19 min of usable sun.

Where the Anker SOLIX 555 PowerHouse 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 Anker SOLIX 555 PowerHouse ranks 37 of 57, where 1 is the cheapest capacity in the band. That is mid-table: neither the bargain of the band nor the unit you would call overpriced. 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.

Who the Anker SOLIX 555 PowerHouse 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.
Anker SOLIX 555 PowerHouse questions
How long will the Anker SOLIX 555 PowerHouse 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 Anker SOLIX 555 PowerHouse be charged by solar?
Yes. It accepts up to 200W 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.
What warranty does the Anker SOLIX 555 PowerHouse carry?
Anker SOLIX covers it for 5 years. 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 Anker SOLIX 555 PowerHouse worth it?
At $899.99 it works out at $0.88 per watt-hour. It costs more per watt-hour than the median unit in its band, so the case for it rests on the features rather than on the price. 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 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.
