NiteCore D4 Battery Charger Review

Disclosure of Material Connection: I received this product discounted so that I could provide product feedback to the company and post a product review. I was not required to write a positive review and I do not rate products higher than they should have been. I am disclosing this in accordance with the Federal Trade Commission's requirements.

I recently received a NiteCore D4 battery charger for a product review.  In addition to the battery charger itself, it came with two power cords ( house and car ) and a small plastic battery box.

The specs on this charger are pretty nice - it can charge many different sizes and types, including NiMh, Li-Ion and LiFePO4 batteries.  I also really liked the fact that each of the 4 slots is individually controlled, so you can charge the mix you need.  My old charger was just a AA/AAA charger and I had to charge in pairs of the same size/type so this NiteCore was a huge different.

Despite the capable feature set, this unit isn’t complicated at all.  Most batteries it can handle are automatically recognized, you only have to take additional steps for small capacity batteries and LiFePO4 batteries.

Types of batteries I tested:

- 18650 2200 mAh Li-Ion battery
- AA Eneloop 1900 mAh NiMh battery
- AA Energizer 2450 mAh NiMh battery
- AAA Duracell 850 mAh NiMh battery

Testing out the charger

I tried a mix of batteries and every single one charged without a problem, and without having to take additional steps to set a certain mode or select the type of battery.  Initially I found myself messing around with the unit to look at the voltage etc, but this really is a “set and forget” type of charger.  I was worried that the charger would be complicated, and not usable by others in the household that prefer to just drop the batteries in and let it charge like the old charger - I was glad to see that unit worked great without having to be setup each time.

Bottom line: This is an impressive charger that can handle normal household AA/AAA rechargeable batteries with no problem, but can also handle a wide range of batteries that are starting to become more common.
