Charging The Battery – Sunjack Portable Solar Charger

Charging The Battery - Sunjack Portable Solar Charger 1

I'm continuing to test and experiment with the Sunjack portable solar charger, and today I'm testing the battery charge time. The 8000mAh battery is completely empty, and I'm using the 14 watt 4-panel solar charger in direct sunlight.

The test went pretty good, the only thing was that the indicator lights threw me off a little bit. There are 5 indicator lights on the battery, each one signifying 20% charge–so when all 5 are lit up, it's 100% charged. After several hours of charging, the battery only showed 1 indicator light on, and a 2nd one blinking (which to me looked like it was still working on the charge between 20-40%). I unplugged the battery from the charging panels however, and when I turned the battery back on, all 5 indicator lights came on, showing full charge.

This is a great little unit, and so far, I'm impressed. Would be a great prep for a bug out bag or a car kit. Perfect for charging phones, HAM radios, backcountry GPS units, tablets, cameras, satellite phones, and other small handheld devices.
