Never mind… Posted on wrong product.
Looking at the data sheet, anew things occur to me…
1. Max charge current is 100 mA on USB power and 280 mA on DC power supply even though common 18650 lithium ion batteries have a max charge current of about 500 mA.
2. Suppose charging a lithium cell yields a 20% efficiency loss, then a 3000 mAh capacity Samsung lithium battery will take 36 hours on USB power or 12.9 hours on DC power.
Am I looking at this right?
No public wish lists :(
