I cannot be happier with this product! chargers my Fenix batteries (and others) flawlessly. Works great with my power bank so I can charge on the go while hiking. Love the fact it has surge protection and indicator lights so I know how much more I have to go until there is a full charge. This Fenix charger is lighter, more compact, and overall better quality than my prior one so there are all big wins for this charger. This is a must have for anyone with rechargeable batteries!!
