Community Reviews

These compact rechargeable LED flashlights are praised for simple everyday use, with the product description indicating you can turn them off without cycling through every mode. Charging appears to be inconsistent across units, since some charge with USB C to USB C while others only work with USB A to USB C. The sealed battery is another drawback, because the bottom cannot be opened for replacement. The claimed IP65 rating is also questioned due to the zoom design and exposed ports, making this a small, convenient light with a few durability caveats.

  • Some units can charge using a USB-C to USB-C cable with USB-C charging blocks.

  • The flashlight includes a regular USB-C charge input with a rubber-covered port and power switch on the bottom.

  • The deal can work by switching from the Black option to the Grey option when the coupon fails on Black.

    wsm

  • Charging compatibility can be inconsistent, since some units reportedly refuse USB-C to USB-C charging and require USB-A to USB-C instead.

    leecmleecmStadiumRocks

  • The flashlight's bottom is sealed and the battery cannot be opened or replaced, which limits long-term serviceability.

    softridersoftrider

  • The adjustable zoom design and exposed USB port raise doubts about whether the flashlight truly meets an IP65 water resistance rating.

Many of the "Features and Specs" descriptions of these Chinese produced flashlights have not been updated. I tried to extract the battery of my WdtPro battery, but was unable to fully extract it as this flashlight was not designed to allow you to replace the battery. But what I was able to see, I can assure you that it was definitely not an AAA battery.
Thanks for this info. I will pass now.

Black would add to cart but coupon would not apply. Changed to Grey and it all worked.

Some devices will not charge using a usb-c to usb-c cable. They require a usb-a-to-usb-c cable in order to charge. I haven't taken the time to research exactly why this is, but I'm guessing there is some type of circuitry in the device, cables, or both, that cause this dependency. I've owned at least one device that was like this. I only know that these flashlights have this constraint because one of the review videos mentions it. The review is informative and the guy seems generally knowledgeable, so I believe that he's correct about this.*Edit* I went ahead and googled it out of curiosity, and here was the AI Response:-------Some devices require a USB-A to USB-C cable to charge because they lack the proper internal circuitry (specifically the 5.1kΩ resistors on their configuration pins) required to trigger a true USB-C to USB-C charger to output power. [1, 2, 3]Why the difference matters
  • USB-A to USB-C: Traditional USB-A ports do not perform a "digital handshake". They default to continuously sending 5V of power, allowing cheaper or older devices to charge blindly without communication. [1, 2, 3, 4, 5]
  • USB-C to USB-C: True USB-C ports are smart. They require connected devices to communicate power and voltage requirements. Without this communication, modern USB-C power adapters will not send power. [1, 2, 3, 4]
When this happensThis occurs primarily with two types of devices:
  1. Cost-conscious electronics: Devices manufactured to save on costs (like budget earbuds, basic e-readers, or small gadgets) often skip adding the required USB-C communication chips.
  2. Older USB-C devices: Early adopters of USB-C were designed before USB-C to USB-C smart charging became standard. [1, 2, 3, 4]
This is true. I cannot charge my Dark Beam flashlight with USB-C to USB-C cable. It works with USB-A to USB-C cable.

FYI, based on the person's feedback I went ahead and purchased two silver ones and they charge using USB C to USB C. So it may be YMMV on these.

That's a whole lot of talking for 15 bucks
