DISCUSSION

    Newton Power Adapter
    -------------
    The Newton Power Adapter is 3.5 watt, wall-mounted AC to DC power supply. It can be used to power a Newton MessagePad or the optional Newton Fax Modem.

    The cable is 2 meters long and the plug blades are available to conform to the outlet demands of the country to which it is shipped. The U.S./Canada/Japan version has prongs projecting from the end, while the European version has prongs projecting from the back.

    Newton Rechargeable Battery Pack
    --------------------------------
    The Newton Rechargeable Battery Pack consists of four AAA Ni-Cd (Nickel-Cadmium) batteries connected in series, all enclosed in a plastic case. The terminal voltage will be 4.8 volts nominal and the cells should have a minimum capacity of 220 mAH.

    The case will be keyed so the Newton MessagepPad knows that it is a Ni-Cd pack and so discharge appropriately.

    A plastic cover is included with the Rechargable Battery Pack to cover the contacts and protect the terminals from shorting out when the pack is outside the Newton.

    Newton Recharger
    ----------------
    The Newton Recharger is an external, outlet-mounted, Ni-Cd battery recharger. The recharging time is at a "quick charge" rate as defined by the battery manufacturer's specification.

    The input power is universal 85-264V AC, 47-66 Hz for all versions. The wall plug (AC blade) is mounted for all versions:

    * U.S./Japan/Canada

    * European

    * United Kingdom

    * Australian

    The recharger can quick-change four AAA Ni-Cd batteries which have a nominal capacity of 220 mAH. Quick charge rate is 66mA for these cells. Charge time should be approximately 5 hours.

    A rechargeable battery pack and safety cover are included with the charger.

    Newton Battery Booster Pack
    ---------------------------
    The Newton Battery Booster Pack is an external case which holds eight size-AA alkaline batteries. The pack provides more than twice the battery capacity of the internal batteries. It has a flexible cord which connects the Booster Pack to Newton MessagePad's power port. A clip on the back allows for easy portability.
