Volkano wifi mini Ups is a big ****

Don’t ever ever ever buy the Volkano WiFi mini ups, it’s a big ****. Firstly it’s false advertising because it wrote that the ups could last more than 4 hours. On the first day this ups could barely even last 2 hours. As the week went by, the hours decreased. This is the worst product and a waste of money, I regret buying this!! I wish I could get my refund!
