I can't find my charger, can I charge my camera by using my computer ?

Coolpix Cameras are tricky to use with chargers. I will assume your USB Charger EH-69P is 100 - 240V 50/60 Hz so it CAN work in many places around the world with an adapter. Do not go over 240V or you could damage it.

These cameras like to have the power supply connected when it is on to charge - meaning if you have it connected and you plug the charger in the wall it will NOT charge. So if you plug the charger in the wall first and then plug the cable in the camera it will work. The camera is actually ON when it charges and I never REMOVE the memory card when it is ON.

When you have a dead battery. Plug the camera in and make sure the ON LED lights and the Charge LED flashes. Then don't mess with it. Let it charge completely (Charge LED stops flashing and is OFF) and then unplug it. It will turn off. Then later you can turn it on.

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.

Yes to the first and why bother to the second.
You can charge the battery outside the camera using a BC-10L charger or equivalent. One such charger is available here.


The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.


Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa.

The 4100 is a camera, not a battery charger. Connecting the camera to a computer's USB port is only going to drain the batteries faster, since the camera has to use juice to communicate with the computer (even if only to say it has nothing to say).

If you're using an EN-MH1 rechargeable battery pack, you must charge it using a separate MH-71 battery charger. If you're using rechargeable AA batteries, you must charge them using an appropriate battery charger.

The C183 isn't a battery charger. If you use rechargeable AA batteries in it, you must charge the batteries outside the camera using a separate battery charger.

Here's one source for a compatible battery charger.
I can't tell whether your battery is compatible with your sister's charger since you neglected to specify the model of her camera.
You should be able to use any USB cord, but I suggest you don't.

Hi, I'd suggest using a wall charger as they're able to provide more power to charge then a computers USB port. Often with camera's the USB port doesn't supply enough power so the camera doesn't charge at all.

There are 3 possibilities to charge the battery of the camera:

1. Connecting the Olympus' USB cable to camera and computer.
2. Connecting the wall charger to the camera with Olympus' USB cable.
3. Using a specific separate wall charger for LI-50B batteries.

Be sure to connect the cable well and if the orange LED does not light when trying to charge the battery using above points 1 and 2, there might want to exchange the Olympus' USB cable first to check what's wrong. (Cable model: CB-USB6). Another point is to check if the battery is seated well in the camera.

Consider NOT connecting your camera to your computer.

The camera does not charge the battery through the USB port. You have to use the supplied battery charger or an equivalent unit.
