Modern gadgets are power hungry. If you want to make it through a long commute or a cross-country flight without having to plug your tablet or gaming device in, you’re going to need an external battery pack to keep the electrons flowing. Read on as we show you how to shop for a pack that will meet your needs and keep your screens glowing.
Thanks for this; it's really helpful. How would I know the mAh requirements for my devices? On a smartphone, I guess I would remove the battery and find it there, somewhere? On an iPod Nano, of course, I wouldn't remove the battery.
catester -- I assume you mean the mah capacity of the battery. You can find that on the web. Google the specs for the device, for example "samsung s3 specs". The vendor website should have that info.
Even on devices with removable batteries, it's much easier to (as sumatra suggests) just search Google for the stock battery capacity for your device. If you've replaced a battery with a larger capacity aftermarket battery, you should double check it, though.
If you do manually check it though, you'll find the battery capacity on the battery label like you imagined.
Nice topic. Got myself the RAVPower 14,000mAh a few months ago instead of the other one listed above. I prefer the classic black and it has funtioned well by now. Juicy external battery charger is really useful for us heavy battery users.
As for me, I like RAVPower 14000mah one(3600mah larger than the other one). I'm a college student and I don't like to be tied to a wall/outlet to charge my phone. Sometimes I forget to charge my phone, this external battery charger will be very useful.
I have been using a small 3000mAh lipstick charger, which can give over a charge to my phone. I recently got myself an iPad air and I need a larger external battery charger. The two both looks great. But I prefer the RAVPower 14000mAh. It would give more charge to my devices.
LOL, three consecutive people recommending the same thing.
I don't really use an external battery pack - I just underclock my phone to 200 Mhz (no good for anything other than calls) when the battery is low.
