JGmax® Ultra-compact 2200 Mah Portable Charger and External Battery/red(retail Packaging)for Iphone,samsung,htc

This is a neat little power bank that is especially good for someone who needs to keep their phone charged until they return home at the end of the school or work day. Only 2.25"x1.75"x0.75" it takes little space in your pocket and will hardly be noticed in your purse or backpack.I say best for those with only a phone to keep charged because this is a 2200 mAh power bank which means you have about 1870 mAh of power in reserve, about what it takes to recharge your phone one time. All power banks lose about 15% due to resistance when transferring power to a device like a phone.The power bank has just one charge port, which is enough for one so small, and outputs 1.5A, not enough for a fast charge of a tablet, but more than enough for a phone.Another thing I like about this power bank is the build quality, it is very well made.The usual 4 tiny, blue LED lights indicate what is going on when you charge the power bank and charge a phone or other device with the power bank. Between times there is a button to press; each light that is lit is 25% of the total capacity.Included are an unusual, first of the type charge cable I have seen. At one end is the connector to a USB port on your computer, power bank, etc., on the the other is a fitting into which you can plug one of the pieces provided. For example, if you want to plug into the micro charge port on an iPhone, use that piece. If you want to plug into the micro charge port on an Android device, use the appropriate piece. Also included is a well written user guide.Sample provided at a discount to test and review. If were larger, like 4000 mAh or more, I would give it 4 stars because it outputs at 1.5A. But because it is small, well made, inexpensive and only 2200 mAh I am giving it 5 stars.

 I like the small, no-nonsense style of this power bank. It is very easy to use: just plug it in for a few hours to charge it up, then plug in your phone or other device to get an extra charge. Note that there are no unneeded bells and whistles on this charger like lights or temperature monitors. It just does one thing: acts like the battery that it is. Some of the other power banks I've tested are huge and cumbersome to keep with you; this one is easy to keep in just about any bag for that moment when you need it.Note that this is a 1.0 amp charger, which means that it will charge some devices (like a phone or iPad) more slowly than a 2.0 amp charger. However, when plugged in it does the job of charging and holds ample power for a backup. I would be a bit happier if this thing put out 2.0 amps, but it does the job as is so I still like it.If you want a huge power bank for charging a laptop or multiple devices, they certainly exist. I see several on Amazon. The only downside is that they cost quite a bit more.ʕ•ᴥ•ʔ  Spencer in Seattle original reviewI was provided a free sample in exchange for my honest review.
