I just got my LiPo charger today, and I immediately connected it to my computer’s USB port. At that point, the LED flickered and a puff of smoke came out, and then the LED went out. I reconnected it and now the 5V line reads 3.9V, the SYS line reads 4.2V, and the BAT line also read 4.2V. Has this happened to anyone else?

If it has lots it’s magic smoke, chances are it’s not going to work anymore.

Get in touch with SFE support and let them know, it sounds like it had a short on the board.
