Multi-port charger:

You probably have multiple devices that charge from USB. You will want to have a multi-port charge adapter like this one that I bought:

This is a 6 port 60w charger, meaning each USB charge port will charge at a full 2.4A. Some cheaper or inferior ones will have many ports but may charge slower when multiple devices are charged at the same time.

Cheap smaller dual port charger:

Unless you’re looking at a Quickcharge 3.0 charger, a generic USB charger shouldn’t cost $30, $20 or even $10 bucks. It’s so widely mass produced and there should be an affordable one that works, right? Unfortunately, finding a good, fast charger that’s cheap is a challenge.

I chose this one based on specs:

It’s a dual port 5V /2.4A charger that cost me $4.50 each. (2 for $8.99). The total charging for both ports combined is maximum 2.4A. This will charge much faster than the cheaper 1A chargers. You should avoid purchasing a 1A charger as most devices these days use much more than that for charging.
