• Card reader. This portable multi-card reader is a small device specifically designed for fast, easy data transfer and exchange using multiple types of memory cards (such as MMC and SD) without the need for an adapter.
   
• Professional Headset With Microphone. Use it with the Language Teacher program, listen to recorded books, listen to music.
  
• LCD Protecting Film. Helps keep your screen looking great.
  
• Extra Stylus. Funny thing about an extra stylus. If you have one, you'll never use it. If you don't have it, you'll keep losing your stylus and replacing it with a new one. Kind of like that one time you leave the house without your driver's license....
  
• Storage Pouch. This is a nicely made pouch, and your translator fits snugly inside it.
  
• Set of AC travel converters. This is actually the World Travel Adapter Kit. It allows you to connect to international power outlets, because it contains plugs for Europe, Middle East, Africa, Asia, South America, China, Tahiti, Caribbean, North America, Philippines, Australia, New Zealand, South Pacific Islands, Great Britain, Ireland And Hong Kong.

• Mini-USB connection cable. Works with any USB source, which means you can recharge your translator battery quite a few different ways.

About USB

USB is a defined term, and any USB devices must follow the IEEE standard for USB. For power supplies, as an example, it means 5V output.

Mobile devices and battery drain

Mobile devices are always on. Nobody wants to reboot a smart phone just to make a phone call. Thus, a mobile device constantly drains its battery even if the screen is turned off or it goes into standby mode. After a few days, that drain can be significant. For most reliability, don't go more than a couple of days without charging for an hour or two.

How to have healthy batteries

When using any USB charging source, follow the charging limits of the li-polymer battery device you are using. Note that, typically, the manufacturer does not provide the correct information. So, we'll do that here for you.

Most mobile devices do not have robust charging circuitry, to save weight and space. Thus, the only way to prevent overcharging (and thus destroying) the battery is to avoid overcharging. Typically, this means to stop charging after 8 to 12 hours maximum.

The actual permissible time under charge is a function of the battery capacity in mAH and the charging rate of the adapter/charger. But it's not simple division to know that time. The output number on a charger is its initial rate. That rate slows dramatically as the battery charges--think of back pressure when you are trying to blow up a balloon and how it gets harder as the balloon fills with air. Same thing in a battery.

Li-poly batteries accept partial charges and do not develop memory. Charge them frequently for a couple of hours and they'll last a very long time.
