Review on Tokeyla Thor Fire 18650 Flashlight Bundle – 4PCS 3.7V 5000mAh 18650 Rechargeable Batteries with 4 Slot USB Battery Charger | High 4000 Lumen Zoomable Camping and Hiking Flashlight (Black) by Amanda Smith

I bought this kit mainly for batteries so they can be charged and ready for my two LED work lights which require 18650s. The standard bulb in my flashlight (Bauer by HF) runs for 2.5 to 3 hours, only dims slightly until the power LED turns red, and then turns the light off briefly. All 4 of these batteries, rated for more than double the HF batteries, will gradually begin to discharge over a period of 5 or 10 minutes, after which the red low battery indicator will illuminate. It will still work and get darker until they die, but it's useless and frustrating. Also, they are shorter than other batteries I have. The flashlight is nowhere near as impressive as one might imagine from a 2x18650 flashlight. My Microstream USB is actually brighter. But it was cheap, so here's the thing.
