RAVPower has made numerous powerbanks or external battery packs with each version improving upon the other.
One of the most important things about RAVPower is their reputation and reliability. Unfortunately, like the flash memory market, there are many manufacturers that flat out lie on the rated capacities on their devices. If it's too cheap to be true then it probably is a counterfeit. That's why it's essential that you buy from a trusted manufacturer. Here is a link detailing some unscrupulous counterfeits.
In terms of function, the device is very easy to use. Just plug into any AC adapter with at least 1.5 amps rating (if you want to charge at 100% speed, lower ratings are fine, but expect longer charging). A full charge using a 1.5 amp source takes about 7 hours. This can be significantly shortened if you device to use RAVPower's high draw charger or a AC adapter with higher amperage available. The device can charge itself and two devices at the same time (essentially acting as an outlet splitter). Be warned that this device will discharge from the two ports faster than it will charge itself. Even with charging itself and charging two tablets, the unit only got slightly warm. This is important since it means efficiency is high and there is not much energy wasted as heat.
Idle drain on prior versions have been minimal and I expect the same from this device. I once left the prior
version in my luggage for over a month and when I check it, it still had 100% charge left.
I wanted a large capacity power bank that could take care of myself and my wife's electronics on trips. This consists of 2 Android Phones (LG G2, 3000mAh) and 2 Android Tablets (LG G Pad 8.3 4600mAh). That's a 15,200 mAh need.
Whether it's at a red light, in line at the DMV or while waiting for the movie to start, we all use our phones and tablets while killing time. But that's usually just a few minutes. Nothing holds a candle to waiting at the airport, especially now with security as tight as it is. But the worst part is trying to find an open power receptacle to plug in your charger - and if you you're stuck sitting on the floor or very close to someone you don't know (or worse with B.O.).
I laugh at those people now. My wife and I can sit in whatever seat we want and charge ALL our devices without worry. Plus we can watch all our movies on the plane w/out worry. Seriously, this beast handles it all. Here's a breakdown of how many times I can charge my devices from 0-100%:
2 phone charges and 2 tablet charges (and some left over for a bluetooth speaker)
5 Phone charges
3 Tablet and 1 (almost) phone charge
2 Phone charges, 1 tablet charge, 2 bluetooth speakers
There are two charging ports, a 2.4A and a 2.1A ports and the unit uses smart charging technology that senses the requirements of the device being charged and will automatically shut off once the device has been fully charged and thats such a great feature and missing on other portable chargers.the unit has a number of LED lights (blue) on top of unit that with a press of power button located on top also will indicate by number of LED'S lit up what percentage the unit has left for use. 4 LED = 75-100% 3 =50-75% 2= 25-50% 1= levels less than 25% and another great feature is the unit has a white LED by the 2 charging ports the activates a "flashlight" with a long press of the power button, really a great feature. with unit fully charged i was able to charge my Galaxy S5 from 5% to full 5x with enough power left to charge my galaxyS4 10%! you get a estimated 500 recharges of the unit so thats alot and should last at least 2-5 years with moderate use.im very impressed with this unit in so many ways but the price is just the best part, well done Ravpower.
