Review: Does what it says - Used a few of these, still trying to find another project or 2 to use them in. Use 2 to power 2 separate raspberry pi nodes for hamvoip with a transmitter. Set to about 6 volts these are powering the pi and transmitter without issue. I'm running them off some salvaged 18650s. Seems to be of good quality, voltage is stable and handles the amp load while transmitting around 1.5 amps in total. Charger seems to have working overcharge protection. I'm not sure how long I left this on for, but I did add an on/off switch between the board and battery as well as the pi project. I'm not sure what the continuous draw is but there is one. I left a pi off for a few days but board directly connected to my battery and I noticed it did not last as long as previous runs. It WILL drain your batteries if not charging.
Review: Great project board - So many awesome features here! 1. Accepts a wide range of DC input for charging 2. Provides and adjustable DC output (the adjuster is sensitive, but hitting 5V is pretty easy) 3. LED for charging status 4. Automatic shutoff at around 2.8V (requires 6-8V input to get the board to wake back up again) All for like $2 a board. I used this on a project where I powered a small drone camera VTX using a 400mAh battery. Worked awesome.
