Default mobile phone charging and lipos

OK - I am in Vladivostok in a limited environment with internet via mobile tethered hotspot. The mobile battery as with smartphines today is rubbish.

I have a power bank of 4000mAh but its only 1S ..... good for topping up but no good for running the mobile.

Its possible that I will have to return here again or to other similar limited situations.

My mind drifts to the lipos I have at home and how to use for this.

What would work ?

Lipo with uBEC ? Set to 5v

3S Lipo powering a car ciggy plug adaptor ?

Lets assume we are going to use 3S medium sized lipo about 2200 ......

Any ideas ?

I bought 12vdc to USB units for my truck. I have 4 of them wired up, they act independently, so I get 4, 2amp circuits.

They work great and I have used them on a 2s hard case battery, as a charger for my phone. I am going to wire one to an XT60, any battery for 7.4 - 25 volts will work.
