Review on 🚲 TESECU LED Bike Light USB Rear Bicycle Light 1300 Lumen 5000mAh Rechargeable Bike Tail Light and Front Light Set: Bright Cycle Headlight for All Mountain & Road Bikes, Waterproof by Adam Rogers

Updated March 11, 2021 After accidentally leaving it in my bag for 30 minutes. It went from 100% to 65%. Updated: September 26, 2020 In no case will this take longer than 5 hours. Estimated to last around 2.5 hours after a few uses. To find out how long it lasts on a charge I used it on 3 different rides. The first ride was about 40 minutes and she was at 90. The second 40 minutes and she was at 78. The third ride was only 1 hour and 15 minutes and she died about 1 hour later. After 60% it just fell off very, very quickly. When recharging for the next ride, it was 55% after 1 hour and 15 minutes of use. For the price and USB phone charging for emergencies, it's a nice touch. The taillight holds a charge for a long time. Original post I saw all the other lights on the Revain and didn't like them. I kept looking and came across this one. It's really bright for cycling at night. The backlight is not too bright, so you won't be blind when you work. The tail light is good but you have to make sure you don't flip it over, it might fall off. Oops. lol. It can charge your phone, but you can't use the light at the same time. On a full charge of 100 I can use it for 35 minutes before it hits 90.
