"This battery is very versatile as a power source and as a power bank. This one stays in my camera kit for charging my camera batteries which have USB-C ports for charging. All that is required is a short USB cable with USB-C plugs on both ends, super easy and super convenient. Oh, by the way, it also serves as a backup battery for the Fenix LD36R flashlight in my camera kit."

"I never had a battery with a built in charger! So I was skeptical and was looking for a separate charger on Fenix site. I could not find one but needed one for my new Fenix light. My consern was not knowing when it would be fully charged? Upon charging the first time I seen a single light on the battery flashing. I figured it would go solid when charged? But to my suprize it had 3 lit lights when fully charged, I thought this was amazing that this small of a battery could have a charger as well inside! I have not yet had to recharge it as I only have this light for dress clothes and I only have had ised it a couple dozen times. It seems to hold a charge well."

"This battery is awesome!!! It offers even more capacity than the standard 5000 battery, and makes a huge difference when running things all night at high levels. Worth the purchase, I wish it would fit in my headlamp battery compartment but it wont, it works great for the PD40R though!"

"This battery is a great little power bank. I've already charged my phone with it."
— Dave B. (5/5)
"I use the 3200 lumen light for mountain biking and it lights the trails amazingly. I have a backup battery in case I extend my night adventures . It’s a small compact powerbank which I haven’t used it as such, but having it gives me reassurance that I have backup capability to charge my phone."
— Hans L. (5/5)
