Customer Ratings & Reviews

This little power station is great for keeping phones/flashlights/camera gear charged on longer outings/camping trips. I used it to run a 12v refrigerator in the trunk, and you can charge the battery off the car while it powers the fridge. Bought in a bundle with the Anker solar panel, pictured.

I've had it about a month and am super happy with it. I gave it a slightly lower rating for Value, but if you buy it when it goes on sale, then it's an excellent value. First, this was smaller than what I expected, it's about the size of those small Igloo coolers yet has outlets for 2 AC (2-prong), 2 USB-A (+IQ), 1 USB-C (+IQ2) and 1 car plug. The AC outlets are for 2-prong plugs, but one of the plugs *could* be a 3-prong, there is a hole where the ground plug fits, however the device is not properly grounded since the hole is in the plastic body and is not connected to the power station. It's not too heavy at 8 pounds. There's plenty of capacity to charge phones and tablets multiple times. It can run small appliances with a maximum of 200 watts, but due to the small capacity, it won't run more than an hour for a 200W device. One cool use is to pair it with a guitar amp as it can run the amp for several hours. The AC outlets put out pure sine wave, so sensitive electronic devices as less likely to be damaged. It could be used as a UPS, but limited to 2-prong devices. I bought this specifically for the LiFePo batteries, which are half the weight of LiIon and have about 5 times the lifetime. I have several Anker devices, earbuds, bluetooth speakers, power banks over the years and they've always performed very well for me. I anticipate this 521 Powerhouse will perform as well over the years. Lastly, it's perfectly sized for charging/running smaller devices including sensitive electronics. It's not going to be much help when the power goes out and you need to run your fridge, but it's not designed for that purpose. Given my positive history with Anker, I will probably by one of their larger battery power generators for temporary use when the power goes out and before I have to wheel out my portable gas generator.

I honestly really liked it. It has a small built in lamp. I took it on a 5 day long cross country road trip/ camping. And it charged 2 iphones about 4 times each, and still had about 47% after the trip. Very well pleased with it. And the size is great too, its anout the size of a lunch box or a normal car battery.

Wanted something to have power anywhere. My main use is with the Samsung Freestyle Projector and Nintendo switch. Have plenty of Mario Kart and Smash Bros on the go. With both I get about 4-5 hours or use. Has plenty of ports. Only wish it had one more usb C port

Does a real good job keeping devices powered and lasts a good while if you’re charging things like phones and tables etc. Charges very quickly as well. The display has a bit of an issue where after a charge it stays showing 100% even after days and hours of use. There’s some remedies for fixing the display but they’re sorta 50-50 on if they’ll work.

This item will support a Microwave oven. Youi can plug about any kitchen item or computer or a cell phone or microwave oven. I cooked a TV dinner using it. Will even support a small refrigerator . For its size it willy packs a wollop.

This is the only power station that BB currently sells that has LiFePO4 batteries. It will last about five times longer than lithium ion batteries. I just bought it but expect good things by what I’ve read online.

Ive used it several times out camping never let me down ive used it with the solar panel pretty decent battery life for several devices.

Small portable and quality made is good. Cant beat this power house with a built in light.

So far so good. Very well made and compact. Comes with a dc charger and ac charger. Looking to buy a second one!

I have USED this powerhouse a lot! I've put it through its paces. Still working adequately and love the voltage meter in dial which shows us how many watts are being pulled. So easy to use. I am going to purchase the solar panel!

I bought this because my light goes out every time it’s rain and i dont have to sit in the dark with this powerhouse i haven’t use it yet but to know if my power goes out i will have it

This has everything to power your weekend getaways

Best power station since it comes with charging plugs, usb ports, and even dc plug

Bright flashlight, lots of charging ports, easy to use!

It’s portable but the battery life is not ideal for me. Battery only lasted less than 2 hours.

Best buy didnt have it in stock but shipped it directly to my house and it got here very quickly. The power station works great and unlike other power stations for around the same price, this accepts charging via 2 inputs at once. The USB C on the front and the dc input on the rear i can hook 2 solar panels up at once, or one power bank and a solar panel and other different combinations! The power station does give 90% of stated watt hours which is nice! The display is very accurate for watts being charged or used. It does allow charging while being used. Overall a great starting unit for anyone looking to have something that can charge multiple devices or run a car fridge or various devices! I bought this to run a setup in case of a power outage. After testing this power station it runs my nintendo switch OLED docked (which also charges the switch), a 32 inch vizio tv with built in 10w speakers for 7 hours. I then used the same tv with a elite pro 800 g1 mini pc with a i3 processor, keyboard, and mouse and it lasts around 4.5-5 hours depending on CPU load. Hope this helps!
