0% chance that these have an IP65 water resistance rating. Adjustable focus lights (zoomies) lack the sealing required to resist water and dust intrusion. And the USB ports make them even more vulnerable.

Don't understand your logic. This has a regular USB-C charge input. So why won't a USB-C to USB-C cable work?

I was surprised to find that the bottom of this flashlight was sealed and could not be opened to replace the battery. The USB-C and power switch are on the bottom. I can only assume that it would not be difficult to provide adequate sealing there. Both the USB-C port and power switch have a rubber cover. The only access is by unscrewing the top zoom len. There are three rubber seals there to prevent water and dust intrusion. Note IP65 just means that it can resist water and dust intrusion and does not indicate that it is waterproof.

I wish you did not have to cycle through all the modes.

A non-replaceable battery is another reason why flashlight enthusiasts recommend avoiding these types of lights.

Official IP65 designation:
  1. Solid particle protection: "No ingress of dust; complete protection against contact (dust-tight). A vacuum must be applied. Test duration of up to 8 hours based on airflow."
  2. Liquid protection: "Water projected by a nozzle (6.3 mm (0.25 in)) against enclosure from any direction shall have no harmful effects. Test duration: 1 minute per square meter for at least 3 minutes. Water volume: 12.5 litres per minute Pressure: 30 kPa (4.4 psi) at distance of 3 meters (9.8 ft)"
Even if this light was IP65 (at $5 a piece, it isn't), removing the zoom lens would break that vacuum seal.

According to the product description, you do not need to cycle through all the modes to turn it off.

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.

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 happens
This 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]

Thank you for the nice research regarding the difference of USB-C to USB-C and USB-A to USB-C.

However I just checked two difference USB-C charging blocks, using my USB-C to USB-C cables and both were able to charge my WdtPro LED flashlight. So I guess it is a YMMV situation.

I guess I could just buy and return it mine requires the A-to-C cable. Thanks for letting me know.
