Troubleshooting:
Fault phenomenon
Fault check and cause
The solution
Unable to charge
Measuring the voltage of 4 groups of batteries. when one of the battery voltages exceeds 4.25V, the protection board will activate overcharge protection.
Pair the battery pack well, do not mix the good battery and the bad battery.
Unable to discharge
Measuring the voltage of 4 groups of batteries. when one of the battery voltages is lower than 2.7V, the protection board will activate the over-discharge protection.
Pair the battery pack well, do not mix the good battery and the bad battery.
Charging/discharging failure
OV, 4.2V, S.4V, 12.6V, 16.8V miswired
Rewire or replace the new board (human failure, no warranty)
Overcharge/overdischarge failure
OV, 4.2V, 8.4V, 12.6V, 16.8V miswired
Rewire or replace the new board (human failure, no warranty)
Discharge protection
Check that the battery pack has sufficient discharge capability and check that the load’s starting current exceeds the overcurrent protection current of the protection board.
Replace the battery pack with a higher discharge capacity, or a protective plate with a larger current (super working range)
Component soldering
There is no connection between one of the components and the PCB pad.
Repair welding
Component welding
There is a short circuit between two or more pins of the component.
Remove the component and re-weld
Electrostatic breakdown A
In the unpowered state, measure the G, D, and S poles of the MOSFET. If the forward and reverse resistances of any two pins are 0Q, it indicates that it has broken down.
Remove the replacement MOS tube
Electrostatic breakdown B
Remove the MOS tube and measure the resistance of the G and D, G and S poles of&

I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited
After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.
This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.
