Light, portable, and easy to use!
on September 18, 2022
Posted by: Michael C.
Found this little device to be useful for keeping phones charged on a road trip, or for bringing some solar power in from a larger PowerHouse into the house for day-to-day use.

Good value overall

Good value for a big station charger. I wish it would hold more charge for the value. But overall it's a great device.

Nice little well designed unit
on September 11, 2022

Very well designed and an excellent value, I ordered the solar panel as well, will be great for short term power outages, but next time I buy one I'd like a bigger one that can power my full-sized refrigerator for a while. These are very versatile, and buying more than one is a must, especially with the 10 year lifespan.

Great little power station

Power station works well for my needs when I'm camping. One charge has lasted me a week. Recharges quickly plugged into my car's cigarette lighter.

The Anker 521 delivers what I want
on August 12, 2022
Posted by: Joe V.
The Anger 521 provides every every power output and charging option I could ask for. It's convenient, charges in 3 hours from a 24v solar/LiFePo4 backup, and delivers sine-wave AC. It would have been 5 stars except the manual doesn't adequately explain the consequences of ECO mode (surprise turn-off in unspecified situations) and the efficiency of the AC inverter (50%) could be better.

Just purchased the Anker 521
on July 21, 2022
Posted by: Bob T.
Bought to charge a Iceco VL45 refrigerator. Testing at home after charging to 100%. Hooked up to my new 12v refrigerator and had 3 power shutdowns before I
found that taking the power station out of ECO more would stop the power shutdowns. Working like a champ. The refrigerator has a low power setting, so
should run my Iceco for at least 18 hours. Initial 6 hour runtime still only used 33% of charge at 75簞F room temp and refrigerator set to 41簞F. Did cool the refrigerator first usually my 110v wall outlet. Wanted to test how long it would maintain a temperature. Note: None of the shutdowns lasted more than
10 minutes and all could have been avoided by not using the power save mode.

Great power bank! It is designed well and it is very portable. Only thing is that that charging is not that efficient.
