ReVIVE SOLAR RESTORE XL is not providing enough power during solar charging

• For first use, please fully charge and fully drain the internal battery of ReVIVE SOLAR RESTORE XL by means of USB / AC power, repeat this full charge/full drain cycle 4-6 times. This will exercise the 4000mAh internal battery.
• The Solar Restore is not an active solar charger. You should charge up its internal battery first, then after a few hours in the sunlight, just connect your mobile device and begin to charge.
• Please make sure that the POWER SWITCH is turned to CHARGE (sun symbol) when charging the battery pack by solar power.
• The ReVIVE SOLAR RESTORE XL should be left in DIRECT SUNLIGHT (some windows can block solar rays) for 13 hours. This will fill the internal battery enough to give off a small amount of charge to a device.To fully charge the ReVIVE SOLAR RESTORE XL, please connect it to USB or AC power for around 4-8 hours for a full charge.

Please contact customer service if the troubleshooting above does not solve the problem.
