 You can see the result above. Using a USB meter (uncalibrated) I charged a new original Baofeng BL-5 battery with 7.4V 2000mAh/​14.8Wh printed on the back. The DC converter ''​OUT''​ provided roughly the same voltage and current as the wall adapter, and the charging time was therefore the same as when using the wall adapter. The USB current was about 0.95A most of the time. You can see the result above.

-When finished the charger had consumed about 4000 mAh, so you will need a USB battery pack of this capacity to get a full recharge of your Baofeng radio. If you have added the diode to enable using the wall charger as well, you can expect that a full charge consumes about 280 mAh (7%) more for a full recharge. ​+When finished the charger had consumed about 4000 mAh, so you will need a USB battery pack of this capacity to get a full recharge of your Baofeng radio.
