Flex5 Ideas

i’ll give this a conditional 5* because it’s so thoughtfully designed for 21700 use as long as you respect the delicate annode cap/area mechanical parameters. 1)The base cap area volume is small for the needed spring leads force, and 2)the annode cap USBC oriface area is thin volume. Heat from iPhone charge use doesn’t help with that. It’s so nice and small and I use to use it all the time instead of the Flex10 because the blinking discharge power level finish is higher than the flex 10 using 2 batteries. I use to use this handy/small USB access exclusively for my iPhone charges and finishing near depleted charges but the Flex10 is more durable from the Flex5 annode cap, and the Flex10 battery cover is removable during warmer use. You can get a lot of use out of this being versitilly small for portabiliyty, and powerfully dense.

Great Idea

The Flex 5 is very proprietary . Flex 5 battery would not fit any competitors charger. Flex 5 Battery would not fit any competitors flashlight . No Competitors battery would not fit into Flex 5 Returned Flex 5

Wonderful

Just wonderfully,it is amazing to be able to use my ledlenser p7r core flashlight finally. I bought it at a yard sale with no charger almost 2 years ago on a whim,and after researching the brand put the light up while I attempted to get a charger, and since I didn't know the extent it was used (or abused)the new flex 5 was the perfect answer to my problem.love love love it!
