So I initially bought this to go with a camp fridge that I bought so I could keep stuff in my car cold for road trips and it worked great! It charges quickly and the battery lasts a really long time depending on what you are powering. According to the estimate on the power bank, it could keep that decently large camp fridge/ freezer charged for almost a week once it gets to the chosen temperature! As a secondary use, I have a motorcycle in a storage unit and I use this with a battery tender to keep it charged for a couple days since there is no power in the unit. You definitely need to consider the wattage of what you are powering when picking a size though. The fridge I bought it for doesn't use much but I chose this size because it has 1800W of continuous power output. In case I ever wanted or needed to run a electric cook pan or something high power like that. I tested it on a small 1200W electric camp skillet and it was easily able to run it at full power and it estimated about 2 hours with that kind of load so that is pretty impressive! Overall, its great! very well built, quiet, holds a charge forever when not in use, and surprisingly useful to just have around if you need to power something away from an outlet for whatever reason.

I have tested every port and charged it twice. All worked flawlessly. Of all my Lithium-related portable power stations, this is by far my favorite. I have used the AC to power a small George Foreman grill, a wafflemaker, a rice cooker, and an egg cooker. On DC it has powered my Resmed CPAP all night without a whimper, as well as using a 12v portable air pump. Next up will be to see exactly how long it can run my 45qt 12v fridge/freezer, but I would be surprised if it is any less than two full days. The USB-A and C ports all charge phones quickly. The 757 charges in less than two hours from the wall outlet! What I have not done yet is charge it via solar, because we have had thunderstorms nearly every day for weeks. Just be sure whatever panels you use, you'll need the actual connector to be XT60. Pros: -Impeccable craftsmanship. It's built like a tank. -LiFePO4 batteries will give years of quality and safe power. -1229WH of power, with 1,500 watt inverter. -Plenty of ports -pass through and the ability to use it as a basic UPS (...in a pinch. For sensitive things like expensive electronics or computers, you would be better served getting a dedicated UPS). -Fantastic information screen that is just about the best in the business. I first had the Anker Powerhouse II 400 a couple years ago, and it was the best information screen around. This one is smaller in size but still provides more info than any of my others be they Bluetti, Jackery, Swarey, or GoLabs. Cons: -Maybe that it is heavy? That's the price for all this power, so not really a con for me, but may be for others. -Constantly needing to hit the display button because it fades out to save power. I understand the reason though. I recommend this for blackouts or post-disaster use to provide some of your power needs. In combination with either solar panels or a regular generator to run long enough to keep it charged after a hurricane, this and a few others can handle most of your needs, even running a 5,000 BTU window unit a couple hours if you absolutely needed it. Altogether this is a 5-star win for me. Read more

I ordered it on 2023-11-29. I've received a newer version of this product!!! It has these improvements over the previous version: > It has Bluetooth and connects to Anker mobile app > Newer Display (like C-1000) > Improved solar charging (600W/60V instead of 300W/32V) The Anker phone apps seems should take care of several common complaints: > You can update the firmware of the unit. > You can control the display timeout, input wattage (100-1000W) and other settings I ordered the PowerHouse 757 to provide power to the gas furnace and fridge during small power outages. I have a gas generator for longer power outages. I also wanted to pair it with the gas generator to charge the PowerHouse, so I would not have to run gas generator continuously. I've bought it because of good reviews and my trust in Anker. It has 1200Wh capacity and cost $800 - which is what I would pay for Jackery 880 Wh with lower capacity (bought at Costco and returned). It also has very fast charge from AC (1.5 hr in my testing) vs Jackery 880 that requires 6 hrs recharging through brick p/s. After buying it, I was alarmed by reading 1 and 2 stars reviews for it here. They are mainly about solar charging and using it as UPS. I think the newer model addressed solar charging complaints. As far as UPS functionality - it is a nice bonus, and it works as long you understand two limitations: 1. it has 20ms transfer time - wich is too long for sensitive devices like computers (that need < 8ms). But for household appliances (like heaters and fridges) - it works just fine. 2. Once the unit runs out of battery during outage - it will shut down. I.e. after power comes back - it will stay turned off. You would need to press power button(s) on the unit to turn it back on. So it is not suitable for using as UPS say for furnace or sum pump - if you are away. But even my APC brand UPS for computer - once it runs out of battery during outage - will shot down and stays off. I would have to manually turn it on after power comes back. I am very pleased with the unit and hope it will serve me long time - based on Anker reputation for quality engineering and product.s Read more
