Compact & Reliable
The charger is awesome; batteries OK. I continue to use the charger non-stop, always have batteries in and out of it, and it has delivered with no issues.Batteries charge fully, at expected speed of charge, and charger is small, convenient, and durable -- 5 Stars.

Great results! Last a long time
I bought these for a few different high drain devises. The first test was in a radio that was left on for many hours. I have not seen this radio stay powered up that long even with Alkaline batteries! They also recharge very quickly! I highly recommend these. Bonai's customer service is the best. I had a question, and they answered quickly!I have no connection with Bonai, just a happy, satisfied customer!

DO THE JOB
The charger does the job, it is small and fits AA and AAA batteries using an ingenious retractable mechanism, charging is fast, however, one of the ports turns red after the regular charging time which is eliminated by applying pressure and turning the battery.

It would be nice to give the buyer time to use the item before buggin us about a review.
I was going to wait to give a review, but the seller is in a hurry.I have been using them for 5 days.they are still working. I only had to charge them for 1 hr right out of the box.They may have been partially charged. So i can not really tell how long they take to charge from dead or how long they will hold the charge.This review is worthless. but they got their review.

Nice batteries, poor everything else
The charger simply doesn't work. It's like it has a loose connection inside, or it doesn't get enough power. The batteries get hot but don't charge in it. I popped them into an old Duracell charger I had, and they charged right up (without even getting hot). The C-cell adapter is a great idea, but these are rough. They're so rough, they scrape through the plastic skin of the batteries when you put them in. I also bought the D-cell adapter version of this product and it has the same problems and more. The batteries themselves are nice and have a good weight to them, so at least there's that.
