While rummaging through my drawer, I was surprised to find a batch of mixed AA and AAA NiMH batteries that had been sitting there for months. I didn’t expect that my new BONAI 16-bay charger would be able to handle such a jumble of sizes and still do a good job.

Turns out, this charger is more flexible than I initially thought.

The first thing I noticed is how easy it is to use. The LED indicators cycle through a quick startup, then show a solid green for empty slots—simple and clear.

When I inserted a few batteries, the red lights lit up on the ports, confirming they were charging. It’s reassuring to see the status at a glance, especially since you can charge different quantities at once.

One feature I really appreciate is the ability to charge single or multiple batteries in any configuration—no need to fill adjacent slots. I tested mixing AA and AAA NiMH batteries, and it handled them without fuss.

Plus, the charger is silent, no buzzing, which makes it perfect for keeping on your desk or nightstand.

Its smart protection features are also a plus. I kept an eye on the temperature and noticed it heats up slightly during long charges, but nothing alarming.

The charger’s overcharge and reverse-polarity protections give peace of mind. The only downside is it can’t handle alkaline or lithium batteries, but that’s expected for a NiMH-specific charger.

Overall, I found this charger to be a solid, versatile choice for anyone with a mix of rechargeable batteries. The price is right, and the convenience of charging many batteries at once makes it a real time-saver.
