Those springy thingies are meant to be pushed through the PCB and the springs will keep the right pressure on the heat sink… They are not meant to be used like you said in the video.
them cells may be LG as they are the only orange cells i have ever seen
Ever wonder what your mail carrier might be wondering with all these international packages ending up at your place?
are they 18650 cells?
cool
So still no info on the battery then? Pretty useless!
CHEAP ping usb powerbank from china i plugged in my super expensive ipad and it want bang…
Those "springy things" are for mounting the heat sink on a PCB. You mount the LED with the light showing through a hole in the PCB and mount the heat sink so that it's pressing against the rear of the LED, using holes in the PCB which those "springy thing" posts go through. Sometimes you lock them into place with a quarter-turn and sometimes it's automatic.
use thermal glue for the cooler
Never mind I got it working! For me I had to double-click to turn on the flashlight and long press to turn it off 👍🏼😊
The flashlight on my power bank won't work? Any suggestions?
Pardon me for being a bit "old school", but the way I'd measure the real-world capacity of a power bank is by fully charging it, connecting a resistor across the output and seeing how long it takes before it cuts out. I'm sure you don't need this, Julian, but maybe for others… A 5ohm resistor across a 5V supply will draw 1 amp. If it keeps going for 2 hours it has a capacity of 2 amp-hours at 5V. That resistor needs to be rated at at least 5 watts, but a bit of simple multiplication and waiting around longer let's you use almost any resistor you have lying around. I hate your videos, it's your fault that I still haven't done the washing-up because they're addictive! (in case of doubt, that's a big compliment, thanks)
At least all their cells are put together with a tab and spot wielded. It's when wires are soldered directly soldered to cells that the device scares me.
"oooo look there's me" haha
Do you know how long it takes to charge?
Got one of those 2 cell power banks after watching this video, dang thing failed me yesterday, went dead, well down to one dot, when I tried to charge would not connect. I tore it down and the USB in plug had seperated at the connection to the board. I tried to solder it back on but then it seperated at the plug. Tore the board off and kept the cells. Case may be used in some future project. Not a lot goes to waste here in the Dakota's. Must come from being raised on a farm back in the 50's.
