Batteries for rca cambio w101 v2


The tablet has a built-in rechargeable battery. The unit comes with an AC adapter (DC IN 5V) to recharge it via an electrical outlet in your home, or you my use a Micro-USB cable plugged into the port and plug the other end into the USB port on your PC/Mac.

If you're having issues with the battery, such that it may not have been used in a long and entered discharge mode. Connect the AC Adapter for several minutes to get it up to at least 5% before attempting to power on.

Even though the battery is a built-in rechargeable, it can be replaced if necessary, and fairly easily IF you take your time 10-15 minutes and have basic skills. A replacement battery for this unit sells for about $10 on ebay.

Charging my juke with a usb cord


Fully charge the battery to maximize playing time. However, it is not necessary to fully charge or completely discharge the battery each time. You can charge the battery by connecting the jukebox either to the AC power adapter (fastest) or to a USB port on the computer. The battery icon in the upper right corner of the screen indicates the remaining battery charge.
  1. Connect the USB combo cable to the AC power adapter, and then plug the power adapter into an AC power outlet. Or, you can connect the USB combo cable to a USB port on the computer.
  2. Plug the combo cable into the jukebox. Make sure that the top of the plug (the side with the arrows) is facing the same direction as the front of the jukebox.

  3. If you are charging your jukebox from the computer's USB cable, turn your jukebox off. If your jukebox is on, it cannot charge from the computer's USB cable. Note: If you are charging your jukebox from the AC power adapter, you can leave your jukebox on as it charges, but it will take longer to charge.

  4. If the jukebox is on, the power cord icon appears in the upper right corner of the display. The keypad's backlight turns on while the battery charges, and then turns off when the battery is fully charged.
  5. When your jukebox battery is finished charging, pinch the two side buttons on the plug, and then pull the plug out of the jukebox.

Hi
Check the Manual
User’s Guide


Hay Don't worry it will work
Note: Some low-power USB ports may not be able to provide enough
charge power. Also note that rechargeable batteries may
eventually need to be replaced as they have limited charge
cycles (which vary with use and settings).

Li-ion Battery
The Sansa e200 MP3 player comes with a replaceable and rechargeable
lithium ion battery. To use the player for the very first time, remember to
fully charge the Li-ion battery. You can charge your Sansa through the USB
port of your computer, a car adapter (not included) USB port, or AC adapter
(not included) USB port.


Please execute the following instructions for charging the battery using
an USB port.
1) Connect the smaller end of the USB cable into an available USB
port on the computer
2) Connect the larger end of the USB cable into the dock connector of
the player
3) The computer must be on for most USB ports to charge your
battery. Your Sansa will show connected and the yellow charging
indicator will appear. The battery level indicator will blink while
charging. You will not be able to play while connected to the
computer USB.
4) To stop recharging, disconnect the cable.
The battery can also be charged using an AC adapter (not included) or
a car adapter (not included) and you will be able to play your device
while charging with one of the adapters. The battery will reach
approximately 70% charge in 2.5 hours and full charge in about 3.5
hours. It is recommended that you fully charge your Sansa e200
before the first use.

Will not take a charge. took two charges prior but has now stopped


I found this online at www.sandisk.com under warranty and manuals link.
I believe they have an excellent Return Authorization system, that if you truly have trouble with your disk player and it's still under warranty, gather your receipts and get on line to get an RMA. I have successfully returned to disc players that were infact faulty (FAT problems) and received two replacement players. Get on it right away. Look at the manaul online too. IT can be very helpful. I've included the Battery info, and the link for the manual at the end.

Installing micro SD adaptor


if you are holding the phone with the camera lens toward you, the micro sd slot is on the right side ...owners manual pgs 11,12

the adapter does not go into the phone

the adapter you got should be the size and shape of a regular sd card...this is for insertion into memory card reader/writers...the micro sd card fits into the top of the adapter....it just makes it easier for you to transfer images to and from your computer or separate digital camera that holds a full size sd card

Just wondering how to connect it to a computer?


Hello,

The Samsung SCH-i730 doesn't have a USB port, but it has a different port that underneath the phone itself. You need to use an adapter so that you could connect it to the computer. Look for the adapter SCH-i730 Lil Sync USB connector.

There could be a possibility that the battery is not working correctly. To isolate this, try to use another battery to see if you will get the same problem.

NOTE: To take care of the battery, never charge it if it's not running out of charge. Never unplug the charging battery if it's not fully charged.

Motorola A1200 cell phone battery will not charge with AC chargers


HI,

If your phone is still under warranty the best solution is to get it replaced.The problem is actually with the port of the charger.I mean the hole in which you plug in your charger isn't working properly.Where as your USB port is different and works properly so it charges the battery.So you will have to get this repaired.
