5. Solar panels
PS220 makes it easy to recharge your gear from the sun – we didn't invent solar power, we perfected it.
Here are some things to keep in mind when recharging your gear with solar panels.
1. Solar panels don't store power from the sun, they collect it.
We teach you to COLLECT – STORE – USE, which is the best way to utilize solar power to recharge your gear.
Collect the sun's energy with a solar panels. STORE the power in a recharger. Use the recharger to power your
gear, day or night.
2. Not all solar charge times are created equal.
Most solar panel manufacturers calculate recharge times with the following equation:
Devices Watt Hours/Solar Panel Watts=Solar Recharge Times. So theoretically, a 13 watt solar panel would
recharge a 50 watt-hour recharger in 3.84 hours (50/13 = 3.84) – and this is the number you could find in
marketing material for a solar panel. However, in order to standardize results across all manufacturers, these
tests are completed in laboratory settings. The truth is, on a good, sunny day, you'll received about 50-75% of
your solar panel's rated wattage.
3. Solar works, even in overcast conditions.
Solar panels utilize IR, UV, and visible rays from the sun that can penetrate through clouds. Although the effi-
ciency of the solar panel will decrease in cloudy conditions, you'll still becollecting valuable power from the sun.
4. Keep away from shade and windows.
Although you should seek out the shade on sunny days, your solar panels will collect more power when fully
exposed to the sunlight. Windows also have a habit of decreasing efficiency. So keep those panels outside and
in the bright sunlight.
5. Proper alignment works wonders.
Keeping your solar panel angled toward the sun can dramatically increase solar efficiency. Set it up and let
mother nature do the rest.
6. Troubleshooting
If your devices are not recharged from PS220 follow these steps:
1. Check if the power switch is turned on. If not, press the power button.
2. Check if the battery power is less than 20% on the display. With battery power equal or less than 20%,
PS220 will stop the output to protect the battery pack. Charge the PS220.
3. Verify if your device if suitable for PS220 from the following two points.
a. Please check whether your external device consumes more than the maximum output power of PS220.
b. Some devices with internal batteries, such as laptops or tablets, require higher power during start up.
You might need to charge the internal battery for a time before attempting to start the device.
In such cases, the PS220 may not function a normally.
