The Anker 757 PowerHouse, now listed by Anker as the SOLIX F1200, is a 1229Wh LFP portable power station aimed at van life, camping and home backup. Anker’s product page is live as “Anker SOLIX F1200 (PowerHouse 757)” with promotions dated October 2026 and no discontinuation notice, so it appears to still be on sale. This analysis reads Anker’s specifications against what they mean for real use.
How this review was produced: we do not buy or test the products we cover. This is a desk analysis of manufacturer specifications, manuals and documentation, safety and certification listings, and publicly available owner reports and third-party reviews. Figures are manufacturer claims or reported owner results.
The product card below is a separate Amazon listing for the Anker SOLIX C1000 (1056Wh), Anker’s current model in the 1kWh class, not the 757 PowerHouse reviewed here, which is no longer listed on Amazon.
What Anker Publishes for the 757
Figures below come from Anker’s A1770 product page unless noted. They are manufacturer claims.
- Capacity and chemistry: 1229Wh, LFP (LiFePO4)
- Cycle life: 3,000 cycles; the page says the battery “remains healthy” for that many cycles but does not state the capacity percentage retained
- AC output: 6 outlets, 100-120V, 50/60Hz. The US page lists 1800W maximum in inverter mode and 1440W in bypass mode. Anker’s EU manual (A1770211) and its Japan manual both say 1500W, so the figure depends on the regional version
- USB: 2 x USB-C (one up to 100W, one up to 60W) and 4 x USB-A at 5V/2.4A each
- DC: one 12V/10A car outlet, 120W maximum
- AC charging: 100-120V, up to 1000W; Anker says 80% in 1 hour with HyperFlash, under Anker’s own test conditions
- Solar input: XT60, 11-30V, 10A. The US page says 600W maximum and 0 to 80% in 1.8 hours with 3 panels totalling 600W maximum; the EU manual says 300W maximum
- UPS: switchover in under 20ms
- Temperature: discharging -4 to 104F (-20 to 40C), charging 32 to 104F (0 to 40C)
- Size and weight: 43.9 lb (19.9 kg) and 18.2 x 11.3 x 9.3 in (46.3 x 28.8 x 23.7 cm), both from the EU manual as hosted by a third-party shop rather than Anker’s own page
- Warranty: 5 years
Anker does not publish a surge rating that we could find on its own pages. Surge figures quoted elsewhere come from third-party reviews, so we do not repeat them.
Reading the AC Output Conflict
The difference between 1800W and 1500W matters if you plan to run a high-draw appliance. Anker’s US page lists the higher number, while its EU and Japan manuals list the lower one. Do not assume an imported unit matches the US page. Buy from a seller who can confirm which version you are getting, and read the rating label on the unit itself before running a heater or a large power tool.
Capacity and Runtime Estimates
The runtime estimates below are rough calculations, not Anker claims. They divide 1229Wh by the load and assume 85% inverter efficiency, which Anker does not publish.
- A 50W load, such as a compressor fridge at its average draw, would last roughly 20 hours.
- A 60W laptop would last roughly 17 hours.
- A device drawing the full 1500W would last roughly 40 minutes, and one drawing 1800W roughly 35 minutes.
Heavy loads drain the battery quickly, so the large capacity is most useful for steady, modest loads such as fridges, lights, laptops and routers.
Charging and Solar
The 1000W AC input is the standout. Anker’s claim of 80% in 1 hour comes from Anker’s own test conditions, and a real wall outlet, cable and room temperature can change that, but it is far faster than the slower chargers common on smaller stations, and it means the battery can be topped up between stops rather than overnight. Solar input is where the sources disagree: 600W on the US page against 300W in the EU manual. If you want to size a panel array, check which figure applies to your unit before buying panels. Charging is also limited to 0 to 40C, so a station left in a freezing van cannot be charged until it warms.
UPS Function and Bypass
Anker lists switchover in under 20ms. That is within the range many desktop power supplies tolerate, but it is a manufacturer figure and not a guarantee for every device. Bypass mode passes wall power through at 1440W maximum on the US page, which is lower than the inverter limit.
Weight and Portability
At 43.9 lb (19.9 kg) this is a two-hand lift, closer to a piece of equipment than a grab-and-go camping accessory. Plan on a cart for anything beyond a short carry, and lift with your legs, since the unit is dense and the handles carry the full load. Its footprint is modest for the capacity, but it still takes real shelf space, so measure the spot in your van or cabin before buying.
Who It Suits and Who Should Skip It
On paper it suits van builders, cabin owners and households that want a backup source for a fridge, router and lights, with fast recharge from the wall. The 5 year warranty is a point in its favour. Skip it if:
- You need a lightweight unit for backpacking or short carries
- You must run appliances above the AC limit for your regional version
- You need a published surge rating before you buy
Frequently Asked Questions
How much power does the Anker 757 deliver?
Anker’s US page lists 1800W maximum in inverter mode and 1440W in bypass mode. Anker’s EU and Japan manuals list 1500W, so check which version you are buying.
Is it LFP?
Yes, Anker lists LFP (LiFePO4) chemistry, rated for 3,000 cycles. The page does not state what capacity percentage remains after those cycles.
How fast does it recharge?
Anker says 80% in 1 hour from the wall using HyperFlash, under Anker’s own test conditions, and 0 to 80% in 1.8 hours with 600W of solar panels on the US page. The EU manual lists a lower 300W solar maximum.
Does it work as a UPS?
Anker lists UPS switchover in under 20ms. That is a manufacturer figure, so test with your own equipment before relying on it.
Is the Anker 757 still sold?
Anker’s page is live as the Anker SOLIX F1200 (PowerHouse 757) with promotions dated October 2026 and no discontinuation notice.
Bottom Line
On paper the 757 is a 1229Wh LFP station with fast 1000W wall charging, a 3,000 cycle rating, 6 AC outlets and a 5 year warranty. The main cautions are the regional AC and solar rating differences, no surge rating from Anker, and a weight of 43.9 lb. Confirm the version you are buying before relying on the headline numbers.
