HOW TO CHARGE YOUR ELECTRONIC DEVICES WHILE HIKING || Off-grid Charging Options for Outdoors

There was a time when backpacking or camping meant getting away from all of the trappings of human battery, but our electronics’ batteries as well.

Smartphones, cameras, GoPros, and GPS devices frequently have a rechargeable battery. There are multiple ways to keep these gadgets fully charged and running properly even when we are miles from home.

Tips and tricks to save battery life on your Phone

Power off when you are sleeping.
Dim the screen or turn on auto-brightness.
Update your phone to the latest software settings.
Enable low power mode.
Turn off location services.

Update the firmware by connecting the camera to your phone over Wi-Fi and using the GoPro app to update it.
Turn off Wi-Fi.

1.Battery packs (power storage)
Think of battery packs as a storage unit. You can use the stored power from the battery pack to charge your electronic devices, but you need to replenish your storage unit with new power from a power source. Your power source can be your wall charger, your car charger, or your solar panel. A decent battery pack should provide an iPhone with four full charges and will run you about $50-$150, depending on the battery size and power.

The capacity of a battery pack is measured in milliamp hours (mAh). By comparing the storage capacity of a portable battery to that of the battery in your device, you can get an idea of how many recharges you have available. This is usually stated in milliAmp hours (mAh) or Amp hours (Ah). For example, 2200 mAh = 2.2 Ah. Watt hours (wh) is another measure of capacity. To convert watt hours to mAh: (Wh /Volts) x 1000 = mAh. Smaller USB battery packs have as few as 2,000 to 3,000 mAh, while larger ones can have as much as 10,000 to 15,000 mAh or more. If you're going to be charging multiple devices or you are bringing a tablet along with you, having one of these high-capacity batteries at your disposal will definitely come in handy. Small electronic devices that can be charged with a USB cable need a 5 volt output rating, so make sure your battery pack as at least a 5 volt output port.
Solar panels (power source)
A solar panel on its own is a good way to keep your devices charged while traveling, but pair one with a portable USB battery pack and you'll have a complete energy system. This approach allows you to store the energy that the solar panel generates and save it for use at another time. The larger the solar panel, the more sunlight it collects and the faster it gets converted to power stored in a battery. A smaller panel, though easier to pack, takes longer to charge a battery. Large surface area is also best for conditions such as cloud cover or the low-angled, low-intensity light in winter, or when logistical constraints limit how long you can have it exposed to sun. Solar panels are rated in watts. The higher the number, the more electricity is generated during a given time period. Seven watts is a good number to shoot for.
