I lost the battery charger of my olympus fe-320. Can i charge it using the usb port ?

This camera does not charge via the USB cable, the cable is used to download the photos to the computer.
This camera uses a recharageable lithium battery and the battery needs to be removed and connected to an external battery charger to be charged.
You can download a user manual from this WEB site.

In a convoluted way. The FE-46 uses standard AA batteries. You may use either disposable alkaline or lithium batteries, or rechargeables. If you use rechargeables then you must charge them outside the camera. There are chargers that run from a computer USB port, and there are even AA batteries that plug into a USB port. However, you canNOT charge the batteries by connecting your camera to your computer.

Not every model of the cameras can charge the battery by USB cable. It seems you need a OLYMPUS Li-42B Battery Charger Or a USB power adapter You also can by a Li-42b battery and charger set to save another $2 Wish helpful for you

No, the USB cord will not charge the battery. If anything it will drain it faster since the camera has to communicate with the computer (even if only to say it has nothing to say).

You need to use the supplied LI-41C battery charger.

No. The camera does not incorporate any charging circuitry. You have to use the supplied battery charger to charge the battery. The USB cable is strictly for transferring pictures and videos to the computer.

Try recharging the battery. If that doesn't work, try a new battery.

Use the supplied charger to charge the battery. If you've lost the charger, you can get an LI-41C charger from Olympus. You can also get LI-40B or LI-42B batteries from them.

Very few cameras will charge through USB ports. This is only to connect to computer to access pictures. Your camera will not charge via USB. I suggest to many people that using cameras that take AA batteries is the best cameras to buy when traveling. Many camera owner fall victim to different voltage outlets when travelling.

This camera doesn't have a charger built into it. You can only recharge the battery using an external battery charger.

These cameras can't be charged via the USB because there is no charger built into the camera. You will need to buy a new charger.
