Smart Charger for Trend Airshield Pro

I have a Trend Airshield Pro air circulating face shield. It provides excellent protection from the inhalation of harmful dust and some protection as a face shield. What I don't like about it is that it takes about 14 hours to recharge after you hear the warning beep. And worse, if you leave it plugged in after it is charged you dramatically shorten the battery life.  A replacement battery can run $56 to $70 depending where you get it.  Trend pinched pennies and failed to provide a smart charger that would allow only a trickle charge after the battery reached full charge. 

Fortunately there is a solution. Greg Ketell on the Sawmill Creek Woodturning Forum  provided a description for a solution using an inexpensive charger that you can use. So I decided to make a brief YouTube video showing how to apply his solution.

  1. Thanks for posting this. I've recently purchased the face shield and really like it but was worried about over charging the battery. I can't always babysit the charger so your solution is very appealing.
