I bought such charger in Czech eShop for ~ 7 euros:

Used it during my 5day on bike holidays. I had also cheap (~10 euro)
solar charger, which i used to charge AA batteries during day.

In the end i was quite happy with this solution, but it took me time to
figure out a few things.

First the problem with AA charger is that when you plug it in Neo it
probably gives just 100mA current and the phone seems to be slowly
discharging.

So i tried set chg_curlim to 1000 and turn of display. According to
negative value in current_now the phone was slowly charging, but still
that was not to keep the phone charged.

So i switched strategy and charged phone while it was turned off. This
worked a bit better. I was able to use the phone twice a day to make
calls and keep it charged with batteries from solar charger.

You can see some pictures from the trip here:

Hope this helps
