So I am glad I found this video, I bought this thinking it would be good to help charge my phone and tablets over night as we go camping 2-3 times a year. Saddly it doesn't or at least through the USB port. So I what I did was buy one of those 12V USB C Car Charger Sockets that has the USB QC3 and USB-C PD ports on them. I then used a 2.1-5.5mm DC port with open ends and attached it to the Car Charger Socket with crimping and some shrink tubing. the Car Charger Socket has a Volt read out on it ( shows it holding 12.5-11.5 volts) and charges my phone and tables in 45 mins. With the 2.1-5.5 mm DC connectors there is so many things you can run on this. The fact I can let this run over night and not worried about it overdischarging my Batterys is a freaking godsend You can run anything with that 12V port, so long as its nothing to crazy like a DC-AC interverter but you technically could. I would suggest using an M18 adapter the runs to a 13.8V DC Voltage Converter for that right from the M18 with a Digital Low Voltage Protector Disconnect Switch set at 16volts so you don't over discharge your battery
Great work James! Glad my lil vid could help and even more awesome you used the 12v out with car charger socket! Very creative and viable solution. You probably couldn't run a 230v inverter off this, or at least only a small one as the battery And power source will have current limiting/safety built in. Keep up the great work dude :-)
Thanks for the teardown, I'll be getting one and bodging it to use direct 18V to power my laptop, not sure exactly how yet but that's the art of bodging
nick klaus welcome nick. Glad you found it useful. For 18v direct you could perhaps disassemble, then solder wires directly onto the +/- input from the battery terminals. Then depending on room drill a small hole in the top or side shell and run the wires out to a barrel jack which could then be fed to your laptop. On the inside of the shell tie a knot in the cable so that it can stop the cable from being yanked and ripping off your solder connection points. Hope this helps for the idea of bodging. Good luck!
Would be nice to have seen some conformal coating on that circuit board given the battery is IP 54 rated from memory would be nice if the power board was the same in the event of any drizzle in the rain or something
I would agree. I think the design is out of date now with qc4 and USB-pd protocols too. Sadly I don’t really recommend this product. It’s a bit of a cheapo unit. Although primary use case would probably be for the heated jackets.
There is no point doing water proofing on this device, the USB port is the weakness link and an entry for water. Also there is nothing special about the circuitry for this device to retail for $50.
It works for me to charge my phone and give me another battery for my heated jacket. To power stuff if you don't have a heated jacket the top off is a better investment it has a ac plug
Is the 12V barrel jack output fused to limit how many output amps it will allow? Trying to get a feel for what kind of small scale 12V stuff I might be able to run off that jack.
I can’t recall, but I believe it will be fused. Or had some sort of limiting protection.The 12v out is designed to run the heated jackets, if I had to guess it should be good for at least 2amp, same as the USB output. If that’s not enough you may require a custom solution
@@JimTheCoffeeGuy Thank you for your answer. But I know that some fake ones don't protect the battery from overdischarge. As I can see there are only two wires, and no communication with the battery BMS Do you know it it shut the USB and 12V output off before my battery dies if I leave it unattended?
Mc De Leeuw depends... short answer is no, long answer is not from USB, but possibly if you step down from the 12v barrel jack input. Easiest way would be to add a correct sized resistor to the cable you are connecting to the barrel jack....
7806 Regulator off the 12v supply would work, but most 6v stuff doesn't mind 5V so I'd probably just make a usb to barrel connector for whatever device you're using
