Review on 🔦 Vnina Rechargeable Tactical Flashlight: USB Magnetic Flashlights with COB Flash Light, 4 Models, Zoomable, Waterproof – High Lumen LED Torch for Indoor & Outdoor Use by Brian Schultz

These flashlights (2 pack) seemed like a good buy. I bought a flashlight like this a year ago and it works great. After charging these new flashlights, I realized that they wouldn't last long without charging. They are also no brighter than my original. I decided to run some tests and this is what I found: My original one year old flashlight has a clearly marked 3.7 volt battery with the brand name clearly printed on it and a capacity of "3400 mAh". Batteries in new flashlights don't have a brand or declared capacity on the batteries - in fact, they don't even say lithium-ion. My original flashlight lasts 6-7 hours on a single charge at maximum light output. These new lights only last 1 1/2 hours at full brightness. I synced both new headlights and also replaced the new batteries with my old original battery. The results were always the same: the new unlabeled batteries lasted 1.5 hours, the old "3400 mAh" battery lasted at least 6 hours. Based on these results I would say that the new batteries are around 1000mAh - the weakest battery you can buy. Very bad purchase, sent back today. The cost of replacing batteries with better ones is negligible. Do not buy these Chinese lanterns without making sure that high-capacity lithium-ion batteries are actually installed. It is not worth!
