We have a few major problems with this unit, so I wouldn't recommend this to anyone.
* Very poor build quality - this broke on me day two from a 24 inch fall from my desk. * Very slow charging - It will take around 12 hours to charge a regular set of batteries * Batteries included with this via amazon don't work with most flashlights
PURCHASED CHARGER AND EIGHT 18650 BATTERIES. WHEN ALL IS SAID AND DONE THE BATTERIES DID NOT FUNCTION IN THE FLASHLIGHT. THE SUPPLIER REPLACED THE CHARGER AT NO COST, BUT THE BATTERIES STILL DID NOT WORK. I STRONGLY BELIEVE THE BATTERIES DO NOT MAKE PROPER CONTCT IN THE EQUIPMENT THEY ARE SUPPOSED TO SERVE, AND I BELIEVE THE CHARGER DOES WORK....BUT I HAVE NO MEANS TO VERIFY FOR SURE.
