Negative...USB has only a source voltage with current only allowed to flow away from the hub, in your case, the laptop.

Can I charge my PP39L laptop with a USB cable?

the only thing to be aware of is the voltage cannot exceed that required for the laptop . for example if the solar panel puts out 12 volts you will need an adaptor before the usb connection to reduce the power to the voltage for the laptop

My iPhone is flashing battery and beeping

I assume it is on the black screen with the empty battery. If it doesnt come up with the little lightning bolt to show it is charging then it is likely the cable or charger are dead. try laptop USB charging port instead. Note I have had faulty cables that would lock up each USB port tried until I rebooted. try a friends charging rig that you know works. Another thing to check, is pocket fluff in the charge port which may prevent you inserting charging cabel correctly.

Pls check setting for USB. If it has charging by USB activated. Try and deactivate for a while and charge it. Also try and use another charger for a while to check if the charger you have has any problems.

Let me know if this helps.

Hi so i must charger my ps3 pad to laptop i put to usb laptop and after 24h i try conection to ps3 and nothing i buy new pad and is this same problem if you know why ???

If you are trying to charge your controller with a laptop, you have to make sure the laptop is ON for there to be power to the USB port.

The other thing I think might be the issue is you may have a bad USB cable. Try a different cable or try the cable with your PS3 while the console is turned on and see if your controller charges. You will know the controller is charging when you see the 4 blinking red lights on the top edge of the controller.

Good luck.

How can i charge my battery with USB cable? i have problem with baterry or with baterry's port, i dont know exactly, please help me, thnxx

Because your question is NOT so accurate and clear, I will bring out to you the following scenario:

1- In case you have a problem in the electrical wired cable itself that hold the transfered power to charge the laptop battery then you can't do anything except buying another electrical charger.

2- In case you have a problem with the laptop battery, you can simply remove that battery and straightly connect the electrical wired cable to the slot power of laptop.

3- You recommended charging your batter with the USB cable, which is impossible due to the following reasons:
a) USB cables assemblies are used in the transmission of data across networks in case they are network
b) Cable assemblies are collections of wires or cables banded into a single unit with connectors on at least one end.
c) USB connectors are used with universal serial bus (USB) ports. They can be used to connect USB products together, or to connect USB wires and peripherals to other standard port types.
d) The cable assembly may be used for various computer applications like connecting mice, keyboards, printers, modems or other peripheral devices.

The concept of the above description is that you need a cable that transfer to you a specific voltage from a generated magnetic chain to the receiving destination.

Therefore, USB cable have a huge difference in the capacity of the Electricity cable, where USB cables are for data transfer, and Electrical Cables are for Electric Power Voltage (EPV) Transfer.

I know that you haven't ask for all of this, but the main idea of my explanation is to clarify on why there's NO USB cable that can charge your battery, and those that are charging your phone are doing that through the very low voltage that comes from the vibration of chain magnetic into the USB cable transfered from a higher voltage i.e. Computer, Socket Power, etc...

LG Secret charging

Dr Know, doesn't know what he's talking about. I have a LG KF750 and have experienced the same problem.

Solution - Really jam the cable into the socket! The connection is pretty rubbish. The phone charging icon will (with some force and wiggling) appear on screen. Then carefully put it down and don't touch it!

USB charges very slowly, if charging from a dead flat battery it may take a good 20mins of charging to boot up.

P.S. the red camera light is not supposed to come on when charging. Keep wiggling the cable and the light will go off when the phone charging icon appears.
