Solar Meter — Knowing how much “juice” you’re getting while charging via solar power is a mystery. A new device, the Practical Meter, offers an easy-to-read gauge.
Small LED bars light up to tell you how much electricity is being generated — each lit-up bar equals 1 watt of power. The readout lets you angle your solar panel in an optimal position toward the sun for the fastest charge.
The kit, made by Power Practical, comes with multiple cables to connect with your device. $24.99, available now
