Power Booster Accessory

With the power booster I was able to connect a gel cel with solar panel so that during the occasional weeks when there isn't enough sunlight to keep my tempest powered, there is plenty of power to spare. I love it!

Great Company and products.

I followed the directions exactly to charge my Tempest with batteries. After one week, the battery voltage has increased from 2.30 all the way up to 2.32. Still in ECO mode so I’m not sure what the point is. However, they got more money from me so maybe that is the point. The tempest was sold as a solar charging device (has been replaced once for free) but I think it was oversold as was this battery charger.

I am well pleased with my Backup Power Supply as the solar panels have weakened on my 4 plus year old Tempest device. This was an economical means of keeping my home weather station in operation!

After three years, my Tempest device was unable to keep up with my Winter short days, cold overnight temperatures and, on occasion, several days of limited sunshine. I purchased the power boost and it worked perfectly and as promised. My device now has all the power it needs.
