eBay 98kW LED flashlight (slightly exaggerated) with schematic

Published 2024-05-02
The construction of the light is interesting because it has been optimised for fast manufacture.
The circuitry is ultra minimalist, including the USB charging circuitry that doesn't inspire a lot of confidence. Don't leave one of these on continuous charge.
Other than that, it does work, the beam focus feature works well and it doesn't have too many useless modes.
The cell capacity tests at a very ungenerous 160mAh and the charge circuit does keep trickle charging the cell after the LED has stopped flashing, and when I monitored it for a while it peaked at a slightly uncomfortable 4.27V then suddenly settled back down to 4.21V, making me wonder if it had energised the load briefly when I wasn't there as part of its charge control.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.

I'm not buying any flashlight less than 1MW.
-
Brave to stick your hand straight into a 98kW beam.
-
I'm impressed that a 160mAh battery was able to power a 98kW beam for more than 20ms
-
"It's out. [snort]" It's the snort that really sells it.
-
The fact that it required force to disassemble and didn't just fall apart actually puts it in the top tier of ebay torches
-
Assuming the LED drops 3V, then the battery must supply 32,667A. With a capacity of 160mAh, the light produces 98kW for 4.8μs. Very impressive, I think we can all agree.

If you really could get 98kW from an instrument that size, the National Ignition Facility people would like to hear from you! They could replace all those expensive lasers and initiate fusion with a bunch of pen lights.

Technical team: It's 98mW Marketing team: Let's do a clever "typo"

This deserves a BFI Award. Brute Force and Ignorance.

My eyes still haven’t recovered from the mind blowing power of that torch
-
I must get one to point at my solar panels to charge my Tesla on a cloudy day.

"98 Kilowatts of disappointment". Me too. I wanted to see that irritating burnt squiggle made with the Temu gismo vaporised.
-
The 9 million mAh power bank would be the perfect complement for this 98 kW LED flashlight. They should start selling them as a combo.
-
Brute Force and Ignorance™ would be a great name for a band.

Can I suggest a plumber's pipe cutter to cut through the next thin circular casing.

I've used a 1/16 inch or 1.6mm drill bit held in a small pin vise, and I drill a small hole in the plastic. Then I screw a M3 or M2.5 by 6mm sheet metal screw into the hole I drilled. Now I have a 'handle' to grab onto with a pliers or dikes and give the plastic a strong pull. This allows getting inside to repair. 👍

Ebay watts are on a slightly different scale to regular watts.
-
This is just like those 300000 dB horns for sale on ebay and whatnot, enough power to completely decimate the entire universe and all of it's parallels tenfold in an instant for just 20 bucks! I wonder if one day these incredible ebay sellers will make a flashlight powerful enough to replace the sun when it dies in a billion years 🤔

This flashlight is so powerful you should be careful about the recoil

The power of the sun in the palm of my hand
