Excellent charger. More info than most k ow what to do with.
I bought this charger to supplement an older, 2 bay Nitecore charger since the # of rechargeable batteries in my home has increased. In addition to the extra charging bays, this charger provides the internal resistance value of the battery in each bay as well as more typical info such as voltage, charging current and time on charge. The resistance reading may be a bit unsettling to some who do not understand the variance between cells but it can be used to aide in assessing cell health. Additionally, I like that this charger is powered via a USB cable such that you can use standard cell phone style chargers as well as solar chargers designed for your phone. I find that extremely handy if your an outdoorsman or lose power with no other backup.Verified purchase: YesCondition: New

Best buy in chargers
Love this charger. Displays info about batteries health, charge state, etc. Really well made, feels heavy and materials are quality. I have several Nitecore products, and this charger is a testament to why! It even draws little current to operate, it charges batteries off of my solar panel. Can't go wrong. You will be happy.Verified purchase: YesCondition: New
