Solar panel usb charger diy.

I have a kit. Cost is less than 30. Solder the diode to the red wire on the solar panel with the negative side of the diode marked black facing away from the panel. What you ll need 6v mini solar panel 5v step up inverter usb charger circuit your charger cable flexible and foldable plastic card such as an old credit card.

The central brain of our project is a dc to usb converter circuit. Dc to usb converter. I can make one for under 10 when i buy parts in bulk. Looking at this board we can see that it has the tp4056 chip along with few other.

This diode is rated at forward current of 1a with peak reverse voltage rating of 1000v. The second would be with the same solar panel but to charge 3 7v lithium batteries. The first would be using a 6v 1w solar panel. For simple smartphone charger.

The n914 diode is a signal diode is an electronic component that prevents current in your solar usb charger circuit to travel in the reverse direction or in essence un charge your electronic device the n914 diode is recognizable because it has a red central body with a thin black line on one end. This takes our aa power. With 4 high brightness leds. Built in to the x dragon is a 5v 2a charging port for a 5v gadget and a 18v dc output 18v 2a for charging a laptop or other 18v powered devices.

How the tp4056 work. For lighting with this same battery. Add heat shrink tubing then twist and solder a few inches of fresh wire to the positive side of the diode. Thank you very much in advance.

Thanks to a super sized 40w solar panel charger the x dragon offers a beefy 2 8a amps of power capable of re charging smartphones tablets and even some smaller laptops. Diy solar battery charger step 1.
