No, the amplifiers come with a wall plug.I am thinking to eliminate having to buy a charger and avoiding cutting wire and soldering, maybe I should do this instead?
1. Buy a powerbank with 2 USB outlet ports:
Amazon.com: Anker PowerCore Fusion 5000 2-in-1 Portable Charger and Wall Charger, AC Plug with 5000mAh Capacity, PowerIQ Technology, For iPhone, iPad, Android, Samsung Galaxy and More: Electronics
2. Buy two USB to DC plug cables like this:
Amazon.com: Onite DC Plugs for small electronics and devices universal 5.5X2.1mm Jack to 4 Plugs 4.0X1.7mm, 3.5X1.35mm, 3.0X1.0mm, 2.5X0.7mm with 1x Cable 5.5X2.1mm to USB (4 tips +1 cable): Home Audio & Theater
What do you think?
The ones you listed have an output of 5V, the amplifiers require at least 6V, but 12V will be optimal.
The wall plug you posted is for charging it won't have a high enough amperage output to power two of these amplifiers.
Like I said, the amplifiers come with a wall plug. Why would you buy a different one?
