Power hungry smartphones tend to run out of juice at just the wrong time. Fortunately it’s easily avoided with a USB power bank. To help keep you connected, we have put together a list of the 10 best large capacity models available right now.
This story has been updated since its original publication.
A tiny portable power bank is all well and good, but if you want to charge your phone more than once, top up a tablet or even keep your laptop running, you need a larger capacity.
Power banks over 10,000 mAh can typically give a full charge to a totally dead tablet, or juice up your phone around over three times.
While they are a little more expensive, high end power banks also tend to come with a whole range of handy extra features.
It’s also important to note that a 2A USB port is needed to charge many laptops, or fast charge phones that support the extra current.
Avoid cheap no name brand power banks at all cost. The capacities are almost always a complete fabrication or low quality cells are used. Stick with known brands and you can't go wrong.
One of the biggest portable power banks you can buy, the P-Mega offers a whopping 41,600 mAh capacity.
It’s also got six USB ports, have of which can handle 2 amp fast charging. The P-Mega weighs a hefty 979 grams and measures in at 100 x 100 x 115mm.
It can be hard to find, not to mention expensive, but for high end capacity there is no real competition.
Shop around, but eBay can be one of the better places to pick it up.
