Cigarette lighter adapters are common. I’ve not shopped them in awhile. Chargers that measure individual batteries are best, as opposed to doing so typically in pairs - which can lead to under and over charging. They are a bit of a specialty item and the first one I bought is not made any more.

FWIW, you can now get AA LiFePo4 batteries, last I looked AAA LiFePo4 were not available.

Walmart sells Rayovac Nimh with a 120v charger, a simple solution.

Cosmo Weems on youtube did a solar AA charger video.



His solar panel is difficult to find at one spot. I would want to try pairing it with a link solar 11 watt panel.

It’s been a few years since I bought mine so technology has likely changed a bit, but I went with a USB type charger and plugged it into a largish folding panel that had USB output. Every one of the “solar chargers” I looked at for AA & AAA batteries took forever to charge.

I just charge them when I am driving using a small inverter that plugs into 12v. The 110v battery chargers work pretty fast, an hour or less to fully charge 4 AAA or 4 AA, they are not high wattage draw devices. I find those 110v chargers in the electronics bin at the Goodwill store most times that I go there. You can even find the smaller wattage cigarette lighter inverters in that same bin.

I did investigate getting a 12v charger unit but it was not a situation were there was much difference for power savings versus using a small 110 inverter with a 110 charging unit. I could charge a lot more batteries in the same time frame with this alternative method. Sometimes a small inverter for a 110v device make sense and this is one of those times.
