Finally able to charge Unocho 24V 5A charger and guess what, it doesn't work. I signed up to see if I could return it and it's been two days since the return date. I think I've learned my lesson! This is not my first purchase here at Revain from ShenZhenshi YiShenkejiyouxiangongsi where the quality was below average or didn't work as advertised! Do your due diligence, don't just look at the first few reviews, make sure they are for the same product, look for 1 and 2 star reviews before you buy.
