A question to the reader, have your battery chargers keep keeping up with modern technology?
In the mid-2000s I started using simple battery chargers for stuff like AAA, AA, C and D batteries. It was easier, cheaper in the long run, and easier on the environment to use rechargeable batteries then to buy new ones.
Just about all of my gear used wither AAA, AA or D batteries.
- GPS – AA
- Flashlights – AAA, AA, and D
- Camera – AA
All that changed when I was contacted through YouTube and asked if I wanted to review some flashlights. As various companies sent me free samples which used 18650 batteries, I realized my old battery chargers were not going to work. The chargers I had would only do AAA, AA, C, D and 9 volt.
I got on Amazon and shopped around for a battery charger which would charge 18650 batteries. It was at that time I realized how badly out of date my charging devices were. I had always used a charger that plugged into a wall outlet. The new chargers were USB compatible. To use with a wall outlet, simply get a 110 volt / usb adapter.
