How to become even more mobile, or what to do if there is no 220V outlet nearby?

I think many of us are familiar with this situation when you suddenly find that your phone or Internet tablet is about to run out, and this happens, as luck would have it, at the most inopportune moment for this.
What to do if it is necessary to recharge the battery, for example, sitting at a seminar away from the power outlet, on a picnic far from the car's on-board network, where there is no way to stick the usual charge into 220V?

Having experienced for myself when a discharged battery ruins all plans, in this article I want to talk about the most attractive external batteries that can help me out in such situations.


Since I need a universal device, I will not consider those external batteries that are “sharpened” for a specific phone, I will not consider charging a dynamo with a manual drive, I will not consider dimensional and heavy devices, I will not consider devices with low efficiency solar powered.

What I need? A compact and versatile device with a built-in USB connector, with which I can recharge my phone, tablet, etc. without any problems.

Consider models of external batteries, which, in my opinion, deserve attention.
