USB Charger RAVPower 50W 10A 6-Port Desktop Wall Charger Charging Station with iSmart Technology

What more could you ask for! 4 ports 2 at 2.4 amps and 2 at 1.2. Your covered on both ends of that you need.
2.4 amps charges your high demand devices, tablets and finicky phones. and 1.2 charges your lower demand devices, your Bluetooth speakers and portable battery chargers. Smart charging drops the power to maintain that fully charged state without over powering and damaging your devices. Surprisingly this charged both my hp touch pad and my galaxy note 2 both of which are know to be very picky about their power supply. Either not charging at all or charging a painstakingly slow speed. I had not one issue with this.

Because you supply your own USB cable for your device, i cant think of anything that would not work on. And with so many devices plugging in anymore you really need something like this to keep track of it all. For awhile it seemed like i was running all over the house to plug in my devices. A phone in the bedroom, in the kitchen, the boys phones, the tablet, the remote, my Bluetooth speaker for work, my home Bluetooth speaker, my portable battery back-up, my wife's portable battery back-up.
And inevitably something gets forgotten, and it complicates things.

KMASHI 10000mAh MP816 (2.1 Amp + 1Amp Output,2 Amp Input Fast Charging) Dual USB Portable External Extended Battery Pack Power Bank Backup

Battery on your device low?This item is your solution.I bought this 10000 Mah portable battery charger recently to use at work and for travel.The unit is very easy to use and seems to charge my iPhone as quickly as plugging it in. Charging is as easy as connecting it, turning the unit on and forgetting it.The Kamshi charges the device as fast as possible,can be easily recharged over night.I need a recharge per day, so this should work well.The build quality on this item seems really good and it also looks really nice too.This portable charger has meet and exceded my expectations.

The form factor is ergonomic with it's rounded edges and it's really slim so it's prefect for slipping in my backpack.I like that it has two USB ports on it to charge with, and that one of them charges with 2.1 amps (which charges things really fast).Pressing the one button on this unit tells you how much charge is left on the internal battery of the charger by lighting up 4 LEDs. I think it was designed well with ease of use in mind. Even the two USB ports are clearly marked so you know which on is the 1amp vs the 2amp USB port.So far my experience with the Kmashi has been very good and really beyond my expectations at this price point for an external battery.

iPowerBuddy 10000mah Dual Port USB Portable Charger External Battery Pack

I just received the iPowerBuddy 10000mAh charger and fully charged it to test its charging capabilities. First off, the build quality is amazing. It feels very well built and sturdy with a sleek look.

First, I connected an LG G3 (3000 mAh) charged around 61% and charged it until full, which took about 45 minutes. Second, I connected an iPhone 6 (1810 mAh) with 75% battery and charged until full, which took only 30 minutes. Although it's not an exact measurement, it should give you an idea on how fast of a charging speed you should expect from the unit. This is comparable to (or maybe just a little bit faster) other battery banks that I have tested.

It has dual ports (2.1A and 1A) for charging two devices at once and it also comes with a micro USB cable. It's also very compact at around 8 ounces with dimensions of 5.4 x 2.4 x 1 inches. The LCD screen is a nice addition to get an exact battery level instead of relying on LED lights like most other chargers.
