Review on Convenient USB Charger for iPhone & Samsung - 2Pack Multi Port Wall Charger with 3.1A Charging Power - Compatible with Latest iPhone and Samsung Galaxy Models by Rachel Cooper

Seems like most of the devices I've been using lately need the same charger: phone, tablet, e-reader, even my toothbrush! I bought this 3-port charger mainly because I wanted a higher 3.1A output to charge my latest device: a 20,000mAh starter battery. This charger handled it with no problems. We've had them for six months now and have been using them for all of our USB powered stuff. Nothing to say other than they just schedule the work. Having three ports is also very convenient. We usually have one connected to the phone with three different cables: one for phones, one for Kindles and one for my Shuffle - it couldn't be simpler. This charger is as compact as most dual port versions so it doesn't look bulky when plugged into an outlet. Finally, if you're interested in saving power, this charger will draw zero amps (as measured by my "killer watts" meter) unless you're actually charging something. That means you can leave it plugged in 24 hours a day, 7 days a week without wasting power. If you're looking for a USB wall charger, you can't go wrong with this two-piece set!
