Power Booster Accessory

This battery booster is well-designed and offers multiple power options. You can use 2-8 AA batteries (must be in sets of two) and add alternate AC/DC power if desired. Plus, the energy use is intelligent—it uses the Tempest solar panels by default and, if the voltage drops below the optimal range, prioritizes alternate AC (included)/DC power, if available, and then AA batteries to charge the internal battery. Clever!

In my experience, the dark winter days of east Tennessee are too much for the Tempest solar panels, and I hated missing weather data while waiting for the sun to come out. The battery booster has provided months of consistent reporting and is functioning as promised. I don't have AC power at this location, and was only able to get two months out of 8 standard Energizer Max alkaline batteries from February through March, probably due to a few hard freezes. Lithium would likely last longer, and now that the sun is shining longer, I expect this next batch of AAs will last the entire warm season since they won't be charging the Tempest battery as much.

Although I may 3D print an awning to help, the box has done a good job of keeping rainwater out so far.

Overall, I'm very happy with the build quality and performance!

It’s works as described but should have used a removable rj45 round cable instead of an attached flat cable

Easy to install. Works great.

Works perfectly in my northern climate. Great quality.

Ehhh... It's a battery pack that isn't as waterproof as I might of thought it would be, everything considered...
