Review on Nitecore Universal Charger LifeMods Battery by Hannah Curi

Excellent charger! My other Nitecore 4 bay charger is great but it can't charge 21700 batteries. More importantly, there's even a place to charge specially protected olight 21700 batteries. You'll need a tiny magnet to get them working, due to proprietary nonsense of course, but any other generic 21700s are great too. The charger notifies you clearly when it is connected to the fast charging port so that it can be charged faster. It's capable of charging 3000mAh in a single slot when connected to a QC port, but still only charges at 2000mAh unless you manually set the charge rate to 3000mAh. Read the user manual to find out how to do this if you want. I'm not worried as the default is fine. Very happy with this charger.
