Print Profile(1)
Description
Created a 64mm ducted high-power fan, bought two 10.5ah batteries, but this fan is not frequently used. So, I had a sudden idea to maximize its use. Thus, I decided to modify it into a power bank. It features 3-way QC3.0 fast charging, 2-way USB+1-way Type-C, and supports external power input with a wide voltage range of 6-32v, with a maximum output power of 24w. Anyone with DONGCHENG lithium-ion power tools can use it, making it truly versatile.
The screws used are M3*4.2*5 knurled nuts + M3*10 hex socket flat head screws *4 (two would suffice, used to secure the circuit board) + M3*12 hex socket flat head screws *5. The knurled nuts are installed using a soldering iron.
The switch is a 1288BM flashlight switch. You can choose to install it or not.
If connecting external power, the interface is 5.5*2.1 or 5.5*2.5mm.
Only applicable to DONGCHENG batteries. Other batteries need modifications.
