Review on 35W Rechargeable Handheld Flashlight - 9000 Lumens Spotlight, IPX45 Waterproof & USB Output 6600MAh For Home/Outdoor Use by Dan Cramer

Revainrating 3 out of 5

False Advertising. in my review

Claims long battery life at high power of 35W.With three 18650 batteries at 3,000 mAh. (2,800 is Average for Li-Ion of that type) with a 3.7Vdc rating, You have a 9 Amp-hour battery system.At 35W, the batteries are putting out (35W/11.1V=3.15 Amp-Hr), So in less that 3 hours it will have shutdown.This is not 8-10 Hours.Mathematics is not language based, it is simple numbers.-Mechanical Engineer

Pros
  • Its long-lasting 6600mAh battery can keep the light running for hours, even on high settings
Cons
  • Does not come with a warranty
