I ordered a 32000mah power bank by order number: ctso1424791 but if but for 3300mah capacity smart phone for charging i faced that only 50 % of my mobile charging on 100% powerback backup power. I think it may be defective or wrong configuration. I want to replace that product. Delvered by 4 of february but i kept for charging but very quickly charging is completing and not use ful for smart phone.
How can i approach on this. Was this information helpful? |
