PLEASE EXPECT MUCH LONGER DELIVERY TIMES THAN NORMAL Shipping on a global scale is being affected by coronavirus measures, lockdown caused an increase on shipping and many shipping companies have exceeded their capacity to process the added load.

What is it?

This is a small footrpint 26x44.5mm charger module for DIY powerbanks, chargers and other electronics projects. It uses uP9616 which is certified by Qualcomm® and UL.

Why did you make it?

If you remember those bulky adjustable wall adapters from the 80's and the 90's that allowed you to set voltage via a switch to 1.5-3-4.5-6-7.5-9-12V then you know what i was thinking making this! It makes a very nice adjustable voltage regulator which can be used for DIY projects while it can also stand on its own as a QC2/3 enabled phone charger
