Your phone shipped with a wall charger capable of pumping juice back into one device at a time, but there's a decent chance you have a couple more than one lying around. Want to charge several with one plug? You can.

Over on Amazon you can find the Tronsmart 42W 3-port wall charger. That's three times the devices. And the plug comes with Qualcomm certified Quick Charge 2.0 support in one of those ports. Non-Quick Charge devices draw power at up to 5V/2.4A using the other two. The plug in the back folds for easy storage, and a microUSB cable that supports the faster charging speed comes included.

The wall charger usually goes for $20, but if you enter the coupon code JANQXRAX at checkout, you can bring the price down to $12.

This is $1 less than the last time we shared this product. We don't like to spend much money on the stuff we get solely to power the things we actually enjoy using, so discounts like this one sit well with us.
