Bower Energizer ユニバーサル充電器

Finally, a charger that actually fits all my spare camera batteries without a mess of loose cables on the desk. It's slim enough to tuck into my bag at under a pound, and the 1.75-inch width means it doesn't hog the outlet strip.

This thing holds my spare camera batteries without them rattling around, and the 0.75-pound weight makes it easy to toss in my bag. It's handled both my 3.7V and 7.4V cells without a hiccup, so it's become my go-to for travel.

I was pleasantly surprised by how compact this charger is—easily fits in my camera bag without taking up much space. It handles both my 3.7V and 7.4V lithium-ion batteries without any issues, and the weight is light enough for travel.
