- Reviewed in the United States on February 15, 2022Unit works fine, all the functions it's supposed to have worked like they're supposed to.
I did however return it and bought a smaller 2-bay one instead. I've never owned a battery charger for these types of batteries, I've only used the AA/AAA type. This one is much bigger! I bought it to travel with so I could recharge headlamp batteries, and really wanted a 4-bay charger but it's simply way too big. The 2-bay one is much more feasible for traveling. But this was my mistake since I just hadn't seen these chargers before and how big they are, so I still gave it 5 stars.
- Reviewed in the United States on March 5, 2023Works great just put in what ever type of battery you want to charge it does the rest, if you put in a non-rechargeable it won't work so idiot proof!
- Reviewed in the United States on April 15, 2022Just but the batteries in and let the device take over. You won't be left with a dead battery again unless you don't put them back in the charger to recharge. Get two sets of batteries so you'll always have a fresh set.
- Reviewed in the United States on November 26, 2021This product was delivered very fast, I used it to charge some doorbell batteries.. It worked just as expected and charged them quickly..
- Reviewed in the United States on December 21, 2021It can tell you if the batteries were good enough to charge or discard

5.0 out of 5 stars It will automatically select the correct charge for different type batteries
It will automatically select the correct charge for different type batteries - and can charge different types at the same time. it shows the ma/hr taken to charge a battery - to know what the ma/hr capability is, fully discharged before charging.
