To satisfy that need; On the market they are present portable chargers or power banks to charge your mobile devices, be they a Tablet or a phone.
What is a Powerbank?

Power banks (Bank drums) were the first in a Sample International Consumer Electronics Las Vegas in 2000; There a student made the sample with an electrical circuit and a AA battery.
Recall that at that time the charging capacity of electronic devices, in this case of mobile phones, lasted longer.
However, it wasn't until 2007 when the Apple company launched its signature Iphone phone which didn't have a replacement battery; and charging the equipment only lasted 4 hours, which significantly promoted the use of these portable chargers.
You currently have a large number of Power bank like the pocket-sized ones, which have a capacity of 3000 and 6000 mAh; ultra thin ones which have 5000 and 8000mAh and you can take it wherever you want.
The 10.000 mAh SUVs, capable of withstanding the most hostile environments; those with a large capacity 10.000-20.000mAh and those with a capacity greater than 20.000mAh; custom, solar, automotive, among others.
The unit mAh (milli-ampere-hours) it is used to measure electrical energy over a certain period of time. You can see this regularly in the charging specifications of your devices, which indicate the maximum energy storage capacity a battery can have.
