    After a few years

    Initially I loved it. But it’s one of those things keep for emergencies or in a camping situation. After about the 10th or 12th time using it I noticed a decrease in efficiency in energy stored. If you are hoping to have it fully charged using solar power you were looking at a full month if not longer to get it from charge just by solar power alone. The most ideal way to use it is when you’re charging the phone or whatever electrical device you’re using be sure it’s being exposed to solar power if you’re in that situation where you have no way to plug it in.

    DIY Solar USB Charger: 7 Steps (w/ Photos)

    Just so you know, this page contains affiliate links. If you make a purchase after clicking on one, at no extra cost to you I may earn a small commission.

    I recently made a DIY solar USB charger that, in my opinion, is WAY better than most of the other designs out there.

    It’s portable. It looks good. And it can charge your phone and USB devices faster than the mere trickle put out by most other homemade solar chargers.

    That’s right — it’s a DIY solar charger that you’ll actually use.

    It’s affordable and easy to make.

    Materials Tools


    • 2 3W 9V solar panels
    • 22 gauge stranded wire
    • 5V DC/DC buck converter
    • E6000 craft glue (a hot glue gun is pictured, but this is what I ended up using)
    • Reusable grocery bag
    • Heat shrink tubing (optional)
    • 4 1/4″ eyelets (optional)
    solar, charger, steps, photos, wireless


    • Wire strippers
    • Soldering iron
    • Scissors
    • Safety glasses
    • Multimeter
    • Heat gun (optional)
    • 1/4″ eyelet tools (optional)
    • Hammer (optional)

    Step 1: Prep the Fabric

    For this design, I upcycled an old reusable grocery bag to cut a strip of fabric to which I attached the panels. It protects them and allows them to fold up for easy storage.

    Place the panels, eyelets (if using), and DC/DC buck converter on the reusable grocery bag in your desired layout.

    Tip: I recommend giving yourself 1″ or more of space between your solar panels so they can fold easily. I also gave myself more length than necessary so I could fold the fabric over the buck converter, as you’ll see in Step 6.

    Cut the fabric to your desired dimensions with scissors. (Mine ended up being about 14″ long by 8.25″ wide.)

    Step 2: Wire the Solar Panels in Parallel

    Cut a length of wire to connect the panels’ positive terminals. Give yourself some slack in the wire so it isn’t pulled taut when the panels are folded.

    Note: Because my panels have two pairs of terminals on back, before wiring I used a multimeter to check their voltages. It turned out the terminals that output 9 volts are the two “top” terminals — not the terminals with the “” and “-” signs. Strange.

    Strip and solder the wire from positive terminal to positive terminal. (I decided to orient my panels in opposite directions to lessen the stress on the wire when the panels are folded.)

    Tip: Keep your solder joints as flush as possible with your solar panels. This helps later on when gluing them to the fabric.

    Cut a length of wire to connect the panels’ negative terminals. Once again, give yourself some slack.

    Strip and solder the wire from negative terminal to negative terminal.

    Step 3: Solder the Leads to the Panels

    Cut a length of wire for the panels’ positive lead. It will connect one of the panels’ positive terminal to the buck converter’s positive terminal. Make sure it can reach where you want to place the converter. Don’t forget some slack!

    Strip and solder the positive lead to one of the panels’ positive terminal.

    Cut a length of wire for the panels’ negative lead.

    Strip and solder the negative lead to one of the panels’ negative terminal.

    Now let’s test the panels’ voltage and amperage outputs with a multimeter to make sure we wired everything correctly! Connect the meter’s positive probe to the positive lead and its negative probe to the negative lead.

    What outputs should we expect?

    Well, here are the specs for the panels I used:

    Wiring solar panels in parallel adds the current (amps) together while keeping the voltage (volts) the same.

    Thus, for volts, you should see a number around 9V DC.

    For amps, you should see a number around 666mA (333mA 2). But in real world conditions, expect solar panels to output a little less than their stated current.

    Tip: You’ll likely have to switch the red probe to your multimeter’s other port in order to measure this amount of current.

    Step 4: Solder the Buck Converter to the Leads

    Locate the positive and negative terminals on the buck converter.

    Solder the positive lead to the converter’s positive terminal and the negative lead to its negative terminal.

    Now you should have a working solar charger!

    Time to check that it’s working.

    First, make sure the buck converter is connected properly and working by shining some light on the panels. Its LED should light up.

    The LED is on. Looks like it’s working.

    Next, test your charger by placing it outside in direct sunlight and plugging in your phone or USB device. Your device should start charging.

    My Kindle’s charging light turns on when I plug it in — my charger is working!

    I tested my charger’s output with a USB meter to confirm that the charger was indeed outputting a decent current at 5V.

    It’s outputting 460 mA (about 0.5 A) at 5V. That’s about 2.5W, or half the rate of a standard 5W phone charger. (During real-world use it regularly got up to 3W.)

    According to our solar charging calculator, it will take about 5.7 peak sun hours to fully charge my iPhone XR.

    Definitely not the fastest solar charger, but it’ll top off my battery in a pinch.

    Optional: Shrink wrap the buck converter using heat shrink tubing and a heat gun. I did this to for aesthetics and to protect the circuit board a bit. It covers up the converter’s LED, but that wasn’t a big deal to me.

    Step 5: Glue the Charger to the Fabric

    Grab your glue and the strip of fabric you cut back in Step 1. Glue the panels and buck converter to the fabric in your desired layout.

    Tip: The glue I used bled through the fabric a bit, so you may want to put a piece of newspaper down first.

    Wait for the glue to set. Once it has, touch up any spots you missed, if needed.

    Step 6: Install the Eyelets (Optional)

    Because I’ll be using my charger while hiking and biking, I wanted to install eyelets so I can strap it to my backpack and bike. If you don’t need to attach your charger to anything, you can skip this step.

    First, let’s install the two eyelets at the “bottom” — the side opposite the buck converter.

    Cut a circle in the fabric using the eyelet as a guide. Feed the eyelet bottom through the hole.

    Tip: Since I used such small eyelets I just cut a small X with my scissors. You could also create a hole by poking a nail through.

    Place the eyelet base tool underneath the eyelet bottom. Place the eyelet top on top of the fabric.

    Place the eyelet punch tool over the eyelet top. Hammer the punch tool to install the eyelet.

    Repeat these steps to install the second bottom eyelet.

    Now it’s time for the top eyelets — the ones on the same side as the buck converter.

    To protect the converter, I decided to fold the extra fabric over it and cut a hole for its USB port. (If you don’t want to do that, just install the top eyelets like you did the bottom ones.)

    Then I installed the top eyelets through both layers of fabric, glued the flaps together, and glued the USB port to the fabric.

    Note: Don’t cover up any of the solar panel!

    Wait for the glue to set, and you’re DONE!

    Step 7: Test Your DIY Solar Charger

    Now that you’ve made your own solar-powered charger, it’s time to charge something with it!

    Place it outside in direct sunlight. Plug in your phone or other USB device. Then sit back and relax as you take advantage of all that free solar energy.

    When you’re done charging, fold the charger shut for easy storage.

    This charger doesn’t have a built-in battery. Adding a battery makes a homemade solar phone charger more complex.

    You can easily pair your charger with your battery pack of choice (I use the Anker PowerCore 10000). Charge your battery pack during the day, then use it to charge your phone or USB device at night.
