Review on 🔋 Power Up Your Devices with Antigravity Batteries AG-BTR-2: Batteries & Accessories! by Raffy Baer

I have two of these. It's been working flawlessly for the past few days. What I don't like is how difficult it is to switch between my two trackers in the iPhone app. It was interesting to see how the Ford charges the battery while driving compared to the Subaru. Subaru will be charged with higher voltage. In the morning, both batteries stabilize at around 12.6 volts.
