Reviewed in the United States on January 23, 2024

I love the options this charger has. I love that I can "discharge" the batteries before it charges them. This keeps the battery from having a "memory" and prolongs the battery life. Reading the display is super easy to understand and tells you the charging progress and when the battery is completely charged. It will also tell you if the battery is bad and not able to be charged. It does every size battery and can charge multiple sizes at one time or just one. Some chargers require at least 2 batteries to do its job. This charger has great options and for the price I'd highly recommend it!

Does it's job. It will charge ANY size household battery, that's a rechargeable one. The indicators are good, not too bright, just right. My only concern is durability. It feels kind of cheap, plastic wise. One reason I say that, is this charger is pretty light weight. So thin plastic is used. It has all the usual protections associated with a electric device, so no worries there. Time will tell.

First didn't work, they replaced it.

Reviewed in the United States on July 30, 2023

Color: WhiteVerified Purchase

I have had this for about two years. I finally decided to throw it away. It never seemed to charge very well at the first, but I kept using it because of the cool screen and other features. I have trialed various brands of batteries on it, including new Amazon batteries, and it is very obvious now, that it just isn't charging them. I should have been suspicious when it didn't weight as much as my older charger it replaced.

Addendum. They reached out to me and replaced the first charger despite it being well over the replacement time. Good customer service. I will start using it and update my findings.

Update. It's been about 6 months. The replacement charger appears to be working well.

Was looking for a battery charger to replace the "Energizer Brand" charger that died on me.
What's nice about this one is that it charges AA, AAA, C, D and 9 volt batteries. Charge time is about 4-5 hours for 4 batteries (completely discharged)...about the same as the Energizer charger. It also will let you know if you have a bad battery as well. Good value for the money....and packed nicely as well.

inferior quality

Reviewed in the United States on September 1, 2021

Color: WhiteVerified Purchase

Updated:
The charger is junk. 2 of the 4 banks malfunctioned. They keep giving me an error and won't charge. I have to repeatedly re-insert the battery or put different ones to "trick" it. What makes me angry is that I probably threw away some of the older rechargeables that were likely still good because I believe this thing early on until I got suspicious! Bonai batteries don't seem to hold up well either and I've had Eneloop, Amazon basics, Energizer, Ikea, EBL, and Tenergy. Bonai batteries seemed to die off or decrease capacity a lot faster than these brands. I think in order of best to worst - Panasonic Eneloop, Ikea, Energizer and Amazon Basics (tie), Tenergy, EBL and bottom barrel is Bonai. Do yourselves a favor and skip them in general.

Original:
I had an old Tenergy (clamshell with blue lid) that finally gave out. I liked that one but they don't make it anymore. The ones still out there are being sold for double what they went for. Don't trust chargers used so I found this.

Pros:
- the power cord isn't the flimsy tiny cord. It's a medium duty power cord
- the overall design is not overly bulky
- display light is bright green, the on lights over the bays are bright too (but they are always green???)
- discharge function

Cons:
- it's pretty light. I guess not much worse than my old Tenergy but then again, it was a little smaller. Feels "delicate" - not that you'd drop these things repeatedly but certainly not tank like the old Radio Shacks
- the springs on the charging bay (neg) terminal/holder feels cheap. Feels like they'll weaken prematurely
- the charging bay on the other ones I had hold aaa, aa better with deeper "walls". This has barely any bay walls
- finicky - shows error for some aa that charged in my old chargers. Yes, the Tenergy did indicate if batts were bad. The few batteries that this said was bad, charged fine in the Tenergy's remaining working port.
- does not have a separate display light button. The charger will turn off the LCD display lights after a little and then you can't see what the status is unless you shine a light on it. Again....the bay indicators are always green. why??
- the bay indicators are always green. According to the manual, they turn red with the 9V but indicate green for all the rest all the time. what?

Not sure if I'm sending this back. I think I'd have to bite the bullet and go brand name for the 50 bucks more. I just don't know if I'm comfortable with this this thing. It seems to work mostly...I'll update

Perfectly designed battery charger...

Reviewed in Canada on October 19, 2020

Color: WhiteVerified Purchase

I've rechargable batteries of this same brand. So, I ordered this product because it's very useful for me. This charger is extremely useful for me and best in design. It can charge all sizes of batteries like AA, AAA, B, C and 9V. The best part of this charger is it's smart LCD display which shows how much the batteries are charged with 3 marking accuracy so I can know how much charge has been done or left. There's one blue button given besides the display to start charging or to discharge batteries. This is also shown in the display that if it's charging, discharging or error. It shows error if the battery is wrongly inserted or broken. This battery charger has over charging protection, over heat protection, over voltage protection, over current protection and short circuit protection so I don't have to worry about even if I forget to remove batteries when they are fully charged. I have 2800 mAh batteries and it took between 2.5-3 hours to fully charge all of this batteries at once. Taking all of these things together, it's perfectly designed product I've seen so far.

Color: WhiteVerified Purchase

I bought this only because I can use it to charge AA, AAA, C, D types and also the 9V battery. Best part is just charge one battery and not two like the current standard battery chargers. Only weird part is a tick sound that is audible only if the surrounding is quiet, but then I don't know how electronic stuff works so I can't be concerned but only curious. Maybe they will mention it in their booklet next time. I really really hope this product lasts a long time
