If you plan on carrying a power station away from your campsite or car this is the way to go.

Easy and portable.

I purchased this item to use at vendor events. I used it this weekend for the first time. It ran my register system, I pad, and cell phone for the entire event (9 hours) and still had 86% charge when I started breaking everything down for the day. I have not tested it with anything that pulls more power, but it was great for what I purchased it for. Easy to operate. Very portable.

Professional Use - On the Job

I purchased this unit to be able to charge my laptop while working in the field. I am able to charge my laptop 2 times with the Anker PowerHouse 521 and it allows me to have better efficiency and productivity! Great product, highly recommend! I also use other Anker products and they are always top notch. I will not use any other brand.

Very happy with purchase
Mixing a flow from my other to the Anker battery while the Anker is running gives me 7 hours of battery life

great for backup power on road trips

very sturdy and reasonable weight, love the fast charging usb-c port, and 2 usb-A ports! display is neat, shows the wattage draw of devices being charged, and has a battery level meter 0-100%. 2 wall plugs and a cig lightwr adapter are cool, as well as fast recharging in under 4 hrs by using the included 65w wall plug, in tandem with a fast charging usb-c cable plugged from an outlet into the usb-c port!

Terrible product
on April 5, 2023
Posted by: Pierce
I am constantly having problems with my battery bank. When plugging it back in after its completey drained it will display 100% battery no matter what until you reset it. The charging ports get very loose very quickly and it will not charge easily or properly. Im currently having an issue where its displaying 100% even after resetting it multiple times (after running a fan for an hour). The worst part is that you might be thinking I have a dud... I warrantied the first one and Anker sent me a brand new one. Both are having the same issues.

Excellent Little Power Station
on March 31, 2023

I bought this as back up power source just for running my WiFi Modem/Router. I have a hybrid job, so some days I’m in office and some at home. Last time I was working from home our power went out from high winds and I had to drive in for work. I wish I had bought this earlier! I’ve tested it and it ran my modem and router for a little over 13 hours which is exactly what I expected based on the Wattage draw.
It charges really fast especially if you use both the provided charger and use a 60W USB-C input on the front. 0 to 100 in about 2 hours.
The light is a fantastic bonus, and of course the screen is great, shows you exactly what you need, input/output/remaining percentage.
I plan on buying one of the larger Anker Power Stations to have as a backup for large appliances like the refrigerator and sump pump.
