Camping / Boondocking and Charging Batteries

[Unhooked]

I am going on a 2 week camping trip. We will be living off a 12v deep cell battery that we can recharge every couple days with a small generator running for about 2 hours a day. I currently run through about 1 18650 battery a day and I have 4 of them. In my dual bay wall charger, they take something like 5 hours to recharge - not sure exactly how long but it is more than 2 hours (it is a .5 amp charger). I also have a small inverter, so I can plug the charger in for longer then 2 hours, but I think this may run my 12 volt battery down too quickly - the 12 volt battery we need for things like our camper water pump and lights. Any campers out there deal with the whole mod battery charging situation?

I might have answered my own question. I just ordered one of these: http://amzn.to/2ca6I2T

That charger will give you 1A charging (1000mah) if you have a 2A USB source. That standard is 500ma on most USB outlets, but there are some that go up to 2A.

I'd have some 4000mah to 6600mah USB battery packs to charge from USB while the generator is running.

This is a cool thing to have. Up to 20 hours of 12v power from a charge and it has a 2.1A USB port, 2 12vdc outlets, plus it will jump start your vehicle and run a multi-bay 18650 charger.

this one is kinda a do it all, for me

•it is USB powered, so it plugs into 110v adapter or 12v adapter (home or car)
•outputs .5A or 1.0A (push of a button)
•it charges most all common batteries
•and it is a POWER BANK (by installing a battery in bay, it will out charge from USB)

I like to have some back up, so when the power goes out (storms etc.) it is handy to have full
18650/26650/'D' cells on hand to use for ecigs, cell phones, flashlites etc. ...

* same with this one except a Single, BUT does .5A / 1.0A / 2.0A charge (no Ni-MH)

just my thoughts and what I got /use...

That VC2 Plus looks a lot nicer for only $5 more. Oh well.
