Abstract

A portable power supply which comprises a number of batteries A which can be connected in series to power a device B at around 110/120V using connector block C. To recharge the batteries A the connector block C is used to attach the batteries in parallel to a lower voltage source which for example can be a car power system through the cigar lighter.

Description

Portable Power Pack The device is a series of small 12 volt motor cycle batteries wired in line to produce 96\108\120 volts, enough power to amply work most 120\110 volt safety voltage power tools as used in the building trade ie hand drills Grinders light bulbs planers E. T. C. also electrical equipment of the same voltage in other countries i. e. U. S. A., with the aid of the connector block described on pages three and four, and can be charged with an ordinary low ampage 12 volt car battery charger, the device has been tested upto 1000 watts with a 500 watt drill and a 500 watt grinder, working at the same time. the device"in existence"can produce 30 amps but could produce a lot more using heavier batteries, the device is completely portable ans weighs about 20 pounds, other types of battery can be used to produce 96\108\120 volts such as NICD or similar but wouldn't have the same prolonged output and would cost a lot more the object of the invention is to provide a portable source of power where no mains power exists and supersedes engine powered generators, being lighter, cheaper less (much less.) moving parts can be used in unventilated rooms because there are exaust fumes can be used outside in any weather whereas a generator would be effected by wet weather, the device can provide power to drills lights e. t. c and in ordinary use will last all day (8 hours) other advantages are that one person can carry the device a long way i. e. up flights of stairs in high rise buildings whereas a generator weighing 100 pounds plus would take a supreme effort, also the theft factor, the device can be easily hidden on site or disguised as anything such as a building block battered oil can e. t. c, can be of use to military medical & rescue field operations.

The device has not got to be restricted to any voltages and can be whatever is required but anything of a higher voltage than I 10-120 should be considered dangerous and 110-120 v should still be treated with respect. the individual voltage of the batteries can be anything and not restricted to 12 volts Page 3 wiring layout how to produce 108 volts D.

Claims

Claims 1. A portable power pack made up of series of batteries wired in two ways using a connector block or switch, (see p. 3) the batteries are wired in line to produce any desired voltage and when using the connector block or switch the batteries are reduced back to their individual voltage and now instead of being wired in line are now connected negative to negative and positive to positive and are now of a low voltage in the whole, and can be recharged using a low voltage battery charger or plugged into car cigarette lighter plug or directly into any charger. See page 4
2. A portable power pack which is totally portable can be carried by hand or pulled along on wheels, can be pushed along on wheels
3. A portable power pack which can supply power to electrical appliances of any voltage
4. A portable power pack which can be charged at low voltage and can produce a low voltage and increase to a high voltage
5. A portable power pack which can contain any sort of battery or batteries
6. A portable power pack which can produce a high ampage and wattage (high amps & watts)
7. A portable power pack which can fit into any container or need not be fitted into a container.
