I thought I’d save some money and buy some cheap USB car adapters. I think it cost about $1 each. When they arrived I questioned whether they could actually out put 2.1A and 1A in simultaneously. I opened one up and looked up the chip AD85063, did some searching and came across a similar post. The chip’s datasheet specifies that it can output 700MAh at 5v… This is nowhere close to the 2.1/1.1A specified… I quickly asked the seller for a refund, linking them to the datasheet, and they refunded me my money. Long story short, cheap comes at a cost.
