eBay 98kW LED flashlight (slightly exaggerated) with schematic
77,696
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
-
Technical team: It's 98mW Marketing team: Let's do a clever "typo"
-
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.

"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
-
This deserves a BFI Award. Brute Force and Ignorance.
-
My eyes still haven’t recovered from the mind blowing power of that torch
-
Can I suggest a plumber's pipe cutter to cut through the next thin circular casing.
-
I must get one to point at my solar panels to charge my Tesla on a cloudy day.
-
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.

"98 Kilowatts of disappointment". Me too. I wanted to see that irritating burnt squiggle made with the Temu gismo vaporised.
-
Brute Force and Ignorance™ would be a great name for a band.
-
Ebay watts are on a slightly different scale to regular watts.
-
This flashlight is so powerful you should be careful about the recoil
-
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.

Hey China, THANKS for the flashing mode on torches - thats what was so missing in the last 100 years and thanks for the 'economic' construction so that, despite it not havinbg an incandescent filament, if you drop it once the thing stops working permanently. Thanks, just THANKS!!!

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. 👍

At 98kW that battery will last two-hundredths of a second. 😁
