What can you power with a solar panel backpack?
Here’s an overview of the average power needs of the devices listed, as well as the average power output of solar backpacks:
- Smartphones: 5-18 Watts (W)
- Tablets: 10-60W
- GPS devices: 2-5W
- Portable speakers: 3-10W
- E-readers: 2-5W
- Portable game consoles: 5-20W
- Wearable devices: 0.5-2W
- Rechargeable flashlights or headlamps: 1-5W
- Digital cameras: 2-15W
- USB-powered fans: 2-6W
- Portable power banks: 10-60W
- Two-way radios: 3-10W
These power requirements are approximate and can vary depending on the specific model and usage pattern of each device.
How much power do solar backpacks provide?
Solar backpacks typically come with solar panels that have an output range of 5-15W on average, with some higher-end models going up to 20-25W.
It’s important to note that the actual power output of a solar backpack can be influenced by factors such as the angle of sunlight, weather conditions, and the cleanliness of the solar panel.
In general, a solar backpack with a 5-15W output can charge smaller devices like smartphones, wearable devices, GPS devices, and e-readers reasonably well, though charging times may be longer than with a conventional power source.
For larger devices like tablets and power banks, a solar backpack with a higher power output (20-25W) would be more suitable.
Keep in mind that some devices with high power needs may require more than one charge cycle or may not be fully charged by the solar backpack alone, especially on cloudy days or when the solar panel isn’t optimally positioned.
