Solder a battery, and it does the job. Can be used as UPS. Delivers exactly 5.01V even at full power 1A. Can take up to 1.5A, it will not burn. Has a very nice LED to show used current.
1A is not very much for today phones (which now use up to 1.5A or even 4A), but still, this board is a good start for most projects.
This booster will stop working when battery is around 2.7V. I think this is too low, and may damage the batt. Some other booster stop at 3.0, and it would be better.
Just perfect.
Impression:Powerfull, simple, amazing!;
