Take the phone to camping, sailing, climbing a mountain or trekking is essential because in a same device we have Music, GPS, camera and many rescues have been made thanks to a call made to the fire department.
What I’m going to show you here is how to build a solar charger for your outdoor adventures such as camping, you can hang the sign on the tent and you will never worry about end of load on your cell phone battery.
You will need:
- Set of Rechargeable AA Ni-MH 3.6 v 1800mAh
- solar Plate
- Diode 1A 50V
- DC converter/USB Card
Don’t worry, the scheme is very easy to build, only some solder and ready, you have a solar charger for the day to day.
Let’s get down to the details. First step is to buy the micro DC to USB converter, found in 1 dollar and DX.com by here in Brazil for 10 reals, I’d buy it right here. Opt for those that already comes as the onboard USB, so you avoid having to do more solder than necessary.
When buying the converter, you will see that you have a limitation of 5V on input, that is, put a set of batteries that exceed this value, is able to burn everything. Now that we have defined the maximum converter input, let’s the batteries.
The battery pack is this simple to many electronic devices, especially wireless phones. You can give an improved load performance by increasing the mAh to 2000 or 3000. Rechargeable batteries are already with more than 3000 mAh.
Knowing all the numbers of our magazine, we put the solar plate and do some solder. Stay tuned to some important details when purchasing your solar plate, first is the amount of charge that she will provide for the batteries. Never pass of 10% the amount of Board in relation to mAh battery. In our case, we have a 1500mAh battery, so the solar plate can never exceed the 150mAh.
The amount of volts from a plate is the bigger the better, of course, keeping the boundaries of mAh we bit. The higher the voltage, the less light you need to charge your device.
Now that you’ve got everything, just solder the positives in positives and negatives on the negatives. Attention to what Led is soldier in solar plate. The black stripe has led to point out, since it prevents the energy return and burn something. If you weld wrong, it won’t charge the battery once will be blocking the flow of energy.
Ready! Now you can get the solar plate and hang somewhere, to charge their devices just plug in the USB. Here are some examples of what we did mounted here, remember, it’s not complicated and you will spend a maximum of 30 reais to do everything.
