H=4.0" connector that fits perfectly in the battery, and the newest Lenovo charger port. These are the parts necessary to build a Thinkpad battery power bank.
Quick overview of what this thing does: it's a small board that clips (or velcros - haven't decided yet) onto a battery, and provides a charging port through the usual Lenovo charger. 2 USB charging ports are also provided, allowing any phone or device to fast charge from the Lenovo battery.
There are exactly two functions to this device:
- Recharges thinkpad batteries with the usual Lenovo charger
- Turns thinkpad batteries into a USB power bank
