portable battery charger Jackery 6000mAh discount 78%

I test all battery chargers "small-big", and for all brands, finally i found Jackery portable battery 6000mAh the best, but why the best? now we know that

Jackery portable battery charger you can charge all devices like iPhone 6s, 6s Plus, 6 Plus, 5, iPad , Air, iPad Pro, Samsung Galaxy S6, S5 & Other Smart Devices, Power Bank 

My main reason for buying this Jackery Bar 6000mAh Portable Power Bank is because it advertises '2.1A Output'. I already own several Power Bank units in the 5000-5600mAh range, but none of them is powerful enough to satisfy my Barnes & Noble NOOK HD+ Tablet which demands 2A of charging current (if it cannot get 2A, it falls back to 0.5A instead). This Jackery power bank unit, however, is able to charge the Nook HD+ at full speed without any problems.

I tested the battery capacity of this power bank unit, by connecting a 5-ohm power resistor to its USB port. The unit is able to produce a well-regulated 4.92V at 0.95A (output power=4.67W) for 254 minutes. The total output energy is therefore 19.8Wh, which is consistent with the '5600mAh' capacity rating (3.7V * 5.6Ah = 20.7Wh, minus power conversion loss). In contrast, my other two '5600mAh' power bank units did not perform as well:

- The EC Tech unit delivered total energy of 17.8Wh (10% lower)

- The PowerBot unit delivered 15.0Wh (24% lower)

See the "Output Power vs. Runtime" chart I uploaded in Customer Images section for details.

I've had several battery packs, since smartphone batteries tend to drain rather quickly, and this is by far the best of them. I've used this while traveling to make sure that I always have access to my phone.

There are a few points that make this stand out.

1-Fast charging - Nearly as fast as plugging the phone into a wall socket and way faster than plugging it into a computer.

2-Lots of juice - I got at least three full charges for my iPhone 5 before I had to recharge

3-Device agnostic - It's just a generic USB plug, this will work with any device as long as you have the cord. This is handy while traveling because I might need to charge my iPad or my iPhone (which annoyingly have different plugs at the moment...)

The Jackery is about the same size and weight as an old iPod mini. It's not minuscule, but it's not large. And it's definitely not heavy. Given it's function as a back-up, auxiliary battery, it fits nicely into your travel bag, where you can forget about it until you need it. And you can leave it there for a long time, because it holds an incredible amount of backup power.
