Revainrating 3 out of 5

Batteries are okay, the charger is cheap

I have had Tenergy, Energizer, Rayovac, Duracell, EBL and now Bonai batteries and have to say they are still being tested. I wanted good alternatives so I decided to try these. While I was very lucky with the Tenergy, a few of the 24 I ordered failed prematurely. Energizer had about the same failure rate. Duracell was actually worse than Energizer. Raiovac surprised me, but he's hard to find. EBL.testing, not sure if the memory leak is significant, so I think I'd drop them from now on. I have Tenergy and this is a Bonai charger. Both will charge any battery, but I like Tenergy better. It's much better designed and works much better. Below I will list the cons of this Bonai charger. Why did I choose Bonai? Advantages: - The price of the battery is the main thing, the amount of positive power. Many other brands have a shallower +, meaning that if the cell has battery wells with a small part that holds the positive contact lower, they won't reach. That's one of the main reasons I tried Bonai. They have a higher terminal to be very versatile. Other brands were too flat and Tenergy was nervous. Pay attention to this aspect! - They feel pretty heavy and durable. Feather light, heats up when all slots are loaded. The slot displays overlap. I don't think there is a separation between the indicators. For example you have 3 in a row. The middle one is green, but the light is suppressed by the two red ones. The light looked pinkish-yellowish, but I had to double down. This is a big minus for me. Right now I'm rotating slots when I can. There is no USB charging port. Many seem to pick it up, Tenergy did, it didn't. This charger is only aa and aaa - it seems to last longer than any other charger. All in all it does its job so I can't fault it for that. Are there better quality chargers for the same price? Of course. This combo has a good combination of high power AA, AAA and charger for the price. Would I buy it again? May be. I just want to see how the storage performance and longevity of the charger is. SO See you in a few months or so with an update. I'm leaving 3 stars for now.

Pros
  • ♻️High-quality batteries: AAA batteries can be charged up to 1200 times. Save money by not buying a lot of disposable or alkaline batteries. 80% of the original capacity can be maintained after 3 years of non-use. If the battery is not used for a long time, charge it to 60-80% every 3 months.
Cons
  • No Instructions
