Worked as advertised
Worked as expected. Charges battery and powers my device as needed.
P**.
Works well as a dc boost and charge module, with one exception.
I tried to use one of these on a solar powered 12v device with a lithium battery and discovered one little flaw the unit will not charge AND boost at the same time. With the solar panel on the input the batteries still ran dry. in my application this was a dead end and I had to use a boost module and a charge module to get it to work. if your application Does not require charging while boosting this will work well.

Junk -5 stars
None of them worked. They were all shorted when plugged in. Incredible.
