DIY Solar Charger for Your Cell Phones | A Step-by-Step Guide
The Importance of Cell Phones
You can be left without electricity for an extended amount of time for multiple reasons. Blackouts, fallen power lines, being in a survival situation, or just going on a camping trip can leave you an outlet short to juice up your technology.
Quickly, your phone battery is drained, and your device becomes useless. We have a solution to this problem, and it comes in the form of a portable, rechargeable, DIY solar-powered cell phone charger.
Step 1: Gather the Materials
You’ll need the following materials to make this DIY solar-powered phone charger:
- A short length of stranded wire
- Micro USB cable with a stripped end
- 7805 regulator chip
- 4-port USB hub
- USB power bank
- Solar panel

Step 2: Solder & Mount the Regulator
The regulator plays an important role in this solar phone charger as it charges the power bank. It also prevents damage to the power bank’s internal due to overvoltage.
Using solder, join the USB plug with the regulator and then join two stranded wires on the regulator for your solar panel (+ and -). Apply a small amount of super glue to set up the regulator in the terminal block of the solar panel.
If necessary, trim the regulator’s heat-sink mount. Join the other end of the two stranded wires to the solar panel using solder again.
Step 3: Mount the Remaining Devices
In this step, you’ll need to mount the remaining devices to complete the DIY solar power system. You can use a strong double-sided adhesive to fix the USB hub and power bank behind the solar panel.
In case you want to mount the devices permanently, it’s best to use epoxy or hot glue to let them stay still. Set up the power bank and attach the solar panel’s charging cable to the power bank’s charge input.
Plug the USB hub into the power bank’s output. You can then start charging by plugging your phone into the USB hub.
