How to Use

1. Unfold the solar panel and lay it flat in direct sunlight. adjust the solar panel to make a vertical angle between the light source and the solar panel to achieve the optimal charging efficiency.
2. The solar panel needs to be exposed to direct sunlight, without any cover on the surface.
3. When the indicator light turns red, it means that enough electricity is generated to charge the device.
4. Connect the device charging cable to solar panel, the indicator light will tum green, check whether the device charges, if not reconnect or check.
5. In full sunlight, it takes 4-5 hours to fully charge a 10,000 mah power bank, and about 3-4h fora 4,500 mah cell phone. On cloudy days, you can still use it fo charge ata low speed but it is not suggested to charge cellphone/tablets directly. (very important we will explain this below in reminder)
6. The bag designed on the back of the solar panel can be used as storage bag to store cell phone or other small stuff which is a great space saver. With the two provided 2 carabiners, this solar panel can be locked behind the backpack, which allows you to  charge your devices when walking with the backpack.
7. After finishing charging, Remove the charging cable and fold the solar panel, then place the solar panel in a dry and dust-free location at normal temperature.

Important Reminder

1. This product can reach a max 13w (SV 2.5A) output power (USB tester measured data) in the midday in full sunlight, in the morning or afternoon the output will be lower.
   Please understand that cloudy days the output current will be a lot less than sunny days so the charging speed will be very slow.

2. This solar panel does not have a blocking diode, so when charging different products we need to notice as below:
   For phone/tablet:
   (1) In full sunlight, you can use it to charge the phone/tablet directly.
   (2) When the sunlight is weak, please do not charge the phone/tablet directly, otherwise it will drain the phone battery other than charge. Two different ways to keep charging when the sunlight is weak:
   [1] Please use the solar panel to charge power bank first, after charging a certain amount of power then use the power bank to charge the phone/tablet.
   [2] Tum off the phone/tablet and then connect it to the solar panels to charge (for iphone, please plug in the charging cable to charge first then turn off the phone to prevent automatic power on when charging).
   For power bank and other rechargeable battery products:
   No matter the sunlight is strong or weak there is no draining battery problem, these products can be charged directly by this solar panel.

3. This product cant store the electricity so it can’t be used in the night.

4. When you use it, please hold it gently, do not bend it, do not scratch it with sharp objects, do not knock it with force.

5. The waterproof rating of this solar panel is IP65, so it can sustain the light rain, but cannot be immersed in water.

6. During the working period, the surface of solar panel will become a little hot and this is a nomal phenomenon, it won’t lead to security issues.

7. After long-term use, the surface of the panel may be dusty, blocking the sun’s rays, weakening the ability to albsoro sunlight, thus reduce the charging efficiency. In this case it is necessary to use neutral cleaner to wipe the dust on the surface.

FAQ

1. Can I use it in rainy days?

Not recommended. Waterproof rating IP65, can withstand a short period of light rain, but can't be immersed in water, and probably sunlight is too weak to generate any power, moisture can easily lead to micro short circuit to shorten the service life of the product.

2. Which factors do affect the charging power of solar panel?

(1) Light intensity. The sunlight intensity will cause the output power to fluctuate up and down, in the middle of the day when the sun's angle of direct sunlight is close to 90 degrees, it can be close to the maximum power (13W), in the morning or afternoon the power will be lower. Weather conditions can also cause sunlight intensity changes, haze, cloudy or rainy weather will lead to the actual power far less than the maximum power, (2) Surface temperature. Too high surface temperature will reduce the output power, in the summer in direct sunlight temperature will be close to 60 °C, even if the light is good may be slightly lower than the max power, (3) Angle of sunlight. In the case of good light conditions, maintaining perpendicular between solar panels and sunlight is the right way to get the max large power, + 15 degrees of discrepancy will not have much difference on power.

3. How long is the service life of the product?

Solar panel cell is actually the physical Monocrystalline silicon which can do unlimited cycles of charging and discharging, even after three years of use of the panel, although surface material is aging, the output power can be maintained at more than 80% of original level.
