This model can't be charged via USB ports. It uses replaceable AAA batteries. You can also use rechargeable AAA batteries like Sanyo or Energizer.

Did it worked before? if so It can be something with the USB cable, try diff cable. USB port, try diff port. Also, you can reload the driver, sometimes it helps. It can also be that the internal fuse has possibly blown, unless you are good with a soldering iron it's not a user servicable part as such. If it never worked: Try the driver first. (the original) Good luck.

How I can charge my batteries on my Vivitar Vivicam 8025 if I don't have a battery charger?


Yes, you may charge the battery through the USB connection. Bear in mind that not all computer USB ports put out enough current to charge batteries. You may also use an AC-powered USB charger, such as used for some cell phones.

Batteries & USB Devices & Charging


I see lots of people have trouble with their batteries for their various USB connected devices. Unfortunately you cannot usually charge a totally flat battery, or even a 1/2 charged one... from the USB port. These are only used to "Top Up" the battery... & keep it charged up via a "Trickle Charge". at very low current.If your battery is in this condition then you need to replace it with a fully charged one, and then use the USB to keep it fully charged.Another way is to connect the "Flat" battery up to a power supply or machine that charges them, at the right Voltage (Usually 3 - 6 V) & Current rating, and once fully charged, then use the USB.

I have connected my nanomax ipod to the computer and it is not charging.how should i charge it?


Good morning, afternoon, evening or night; whatever time you are viewing this solution post. Thank you for choosing FixYa to solve your problem. So you have connected your Nanomax iPod to the computer and it's not charging like it's supposed to, and you want to know how you should charge it properly? There are two ways you can charge the battery - charging via your Dock Connector to USB Cable, or the Apple USB Power Adapter (which is sold separately). Here are the step by step instructions to charging your and Nanomax.

Using the Dock Connector to USB Cable
  1. Using your Dock Connector to USB Cable, plug the dock connector end to your iPod and plug the USB end to your computer. Make sure the computer you are using has a USB 2.0 port (check your computer's technical specifications to see if it's USB 2.0 certified). Most USB ports on the keyboards of laptops do not provide enough power to perform charging activities. If you have a Docking Station, plug the docking connector into the station and placed the iPod in the station as well.
  2. Make sure your computer is fully awake and not asleep (meaning in sleep mode).
  3. A fully charged battery takes 3 hours to complete. An 80% charged battery takes an hour and 30 minutes. The battery is charging when it shows the charging icon (a battery not fully shaded in green, with a lightning bolt).The battery is done charging when the "fully charged" icon shows (a green-shaded battery with a 2-prong plug showing).
  4. When you are done, disconnect the cable from your computer.
Using the Apple USB Power Adapter
  1. Connect the Alternating Current (AC) Plug Adapter with the power adapter (if connected already, skip this step).
  2. Using your Dock Connector to USB Cable, connect the dock connector end to your iPod and the USB end to the power adapter.
  3. Plug the power adapter into a polarized wall outlet or surge protector outlet.
I think you connected everything correctly, but the USB port on your computer did not have enough power to charge your battery. If that's the case, you will have to find a computer that has a USB 2.0 port on it (like a desktop PC or MAC, or a car adapter charging device) and connect to it, or use the USB Power Adapter (sold seperately). I think this pretty much answers your question. I hope this benefits you the best way possible. Once again, thank you for choosing Fixya as your one-stop solution spot for your problems. Have a good day, evening or night; whatever time you are viewing this, and visit us again the next you need assistance troubleshooting.

Can I charge my Magellan roadmate with USB cable connected to the computer?


It depends on the Roadmate that you have. :
- If your Roadmate has a separate plug-in port for charging your unit IN ADDITION TO a USB port, then no, your Roadmate cannot be charged using your computer via the USB cable.
- If your Roadmate only has a USB port available for charging your unit, then yes, you can charge it via your computer via USB.
However, please note, according to Magellan, charging your unit using your PC via USB can take up to 12 hours to charge vs. 4-6 hours when using the vehicle power adapter.
FYI: This is mainly due to USB constraints on pretty much all electronic devices. USB cannot carry the same amount of power to a device. It uses what is commonly known as a 'trickle' charge to recharge a device. It carries much less current than a full-blown charger (like an AC power adapter).

I have the Insignia HD camcorder, this is the second one I have and the second time I have this problem. The first couple of times it charges, then I don't use it for a couple of months, try to charge it...


Have you tried using an AC to USB charger?

I know that some products that charge through a USB port are not able to completely and correctly charge from the computers USB port because it is undervolted for what the device needs. (I have the same issue with my cell phone).

Also, may of a computers USB ports will power enough for data transfer, but not enough for charging the unit.

Try using an AC to USB power supply and not the computers USB ports.

Hope this works!

I downloaded latest win 7 drivers, rebooted PC, phone is recognized but not charging.


Hi,
It denotes that USB charging is not supported by uour mobile phone.
If you are using the same socket in your mobile phone for charging whcih you are using for connecting your mobile to computer then there may be USB charging option available for your phone. If you are having separate charging Jack in your phone. Then USB charging option may not be possible. Please refer your mobile phone user manual to check whether the USB charging option is available or not.

I hope this is useful for you
Thanks

No, it may take a little longer if you are charging through the USB port. I normally have mine plugged in while driving, it charges and is in use too. To use GPS with USB. First turn the GPS on (without USB plugged in). Press Battery symbol on screen for about 10 seconds, a test screen will come on. Plug in the USB (bottom of screen shows USB connected). Tap EXIT to return to maps. You can now use it while USB is charging Make sure you turn GPS off before removing the USB cable

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.
