My first disappointment is that this GP powerbank is quite expensive, yet it uses non branded Lithium ion batteries. My second disappointment with this brand is that it seems that GP doesn't use high quality cells. One of the batteries has rusted. If I can upload pictures, you'll see what I mean. Also there isn't any thermal protection.<br />I did a teardown of 3 Xiaomi powerbanks, and I can see the difference in quality immediately. Xiaomi powerbanks costs 1/3 the price of the GP powerbank, but they use quality cells like LG or Samsung, though recently they have started using Lishen's battery cells. They have protection circuits in place and also thermal protection against over heating.aiwentimotaihttps://www.blogger.com/profile/04074022332769514490noreply@blogger.com
