Go to the Place that Charges for the Charger
Unfortunately, USB chargers are going to be the type of product you will always be disappointed with if you don’t buy a durable one at a cell phone or electronic store. Even at high price drug stores, the USB chargers sold with the impulse purchase items by the register are usually made of terrible quality.
So, believe us, the quality of the USB charger is not going to be any better at the dollar store. If anything, it’ll be much worse. A snail will win a marathon faster than your electronics will take to fully charge with one of the USBs if it even holds enough power to complete that job.
