My second one… great PWS

Purchased as a hot backup and in a slightly different location.

Performs well. So far as well as my first Sky/Air.

I’m an original charter purchaser.

No more Power Save Modes And No Missed Data

I live in an Apartment with poor ligthing in the patio. So, my Tempest is going to power save mode ( ~2.35V) very often. Power save mode reduced the frequency of data collection. So missed some weather data points. This booster helped to mitigate that and kept battery at a voltage of 2.77V most of the time.

Also it came with a big lengthy wire ( several feets) to reach the Tempest from the patio from outlet. So, I had no issue in routing the wire.

Installation was quick and easy!!!

Fixed the problem

No more missed data due to too many cloudy days depleting the onboard battery. (Happens a lot around here)

Multiple power options prevent unexpected downtime

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!
