I used this as a emergency backup for my Pellet Heat Stove. Works great. Laster like 45min during power outage. **I did have to pull the fuse for the igniter before using, because that draws too much amperage. If I did not know this, I would have not worked. I manually lit my stove. Read more
Disappointed – Fails After 6 Months with No Support-I bought the Anker 522 as a refurbished unit. It stopped working after 180 days. When I contacted Anker, they told me the 90-day warranty had expired and they couldn’t help. No troubleshooting. No technical support. Just a suggestion to try other devices. If Anker doesn't believe in the reliability of their refurbished products, they shouldn't sell them. It's clear they do not stand behind them. I expected better and will not buy refurbished from them again. Read more
