We stock a variety of accessories suitable for all phones and all budgets, including 12v in-car charging sockets, lighting cables, micro USB cables and power banks. From Belkin USB car chargers to Powerbanks we've got your adventure covered. Internal car 12v multi port usb hub android#Whether you use an iPhone or Android phone, we’ve got the right mobile charging accessories for you. Is the 4.9 volts too low for apple products?Īre the Transistors supposed to put out and actual 5 volts or is 4.Pack some power wherever you’re travelling with a universal charging accessory from Halfords. I am happy that my phone charges from the USB ports but sort of bummed that the Iphone will not. If I plug a premade 12 volt to USB into one of my new 12 volt outlets the Iphone will charge, the output voltage on that USB outlet is 5.1 volts. The output power on the USB ports is 4.9 volts. If I try to charge and Iphone it will not charge, it does not recognize it is connected to a power source. When I plug in my Samsung Note 3 phone to charge using any of the USB ports it charges fine. Have the capacitor going from the 0 volt to the +5 volt coming out of the Transistor. I had the correct resistors on hand for the LED's, for the 12 volt outlet LED's 470 Ohms, for the 5 volt LED's 82 Ohms, for each LED. I bought the components that I did not have on hand from Digi-Key, (2) LT1084CT-5#PBF-ND transistors, (2) P5139-ND capacitors, and (4) C4SMF-BJS-CROU452-ND LED's. Each individual circuit has an LED after the fuse so I know if the fuse blows. Each 12 volt outlet is fused and the USB outlets are fused as 2 pair, so I have 4 fuses total. What I made has 2 12 volt sockets and a 4 slot USB outlet bank off of a CPU board. I built this circuit for my truck, it only has 1, 12 volt outlet. They are nice because of their screw terminals. Of course, you can also use an existing 12v-5v converter in your car, be it light duty, medium, or heavy duty or use these nice power adaptor that are meant to be integrated into other projects or this beefier waterproof, super high power alternative with a heatsink. Also, if you really want to protect your circuit badly, just put one on both sides. So, if you want 1.5 amps for your USB ports, then you select a 0.6amp fuse, if you want 2.5 amps at 5v, you select a 1 amp fuse, if you want 3.75 amps, you select a 1.5 amp fuse, etc.). Because we put the fuse on the 12v side, (which can vary from 11.5-12.5 volts, we have to use a value 2.5x smaller than what we want on our USB side. More information on the fuse: you can use a higher rated one if you use a different transistor that can take higher amperage. If you have a strange LED or want to make it brighter, please use this resistor calculator. Any LED will do, here are the values for the most common LEDs : 1.2v = 220ohm, 1.6v = 180ohm, 2v = 180 ohm, 2.2v = 150ohm.
