Portable battery power station, 12 volts The innovative Lion-cub-go uses a Li-ion battery to create a 3 pound portable power source. It can be charged by a standard USB cell phone charger, using two chargers doubles the charge rate. It is also a battery pack with cigarette lighter output.

Often we get calls from photographers, astronomers, field researchers, CPAP patients, campers, fishermen and plain ordinary people like us who need a convenient source of portable power to power DC or small AC equipment in the field.
The Lion Cub Go™ was developed for this purpose, and can supply 5V, 12V, and/or 120VAC for a wide range of applications.

It consists of a tough high-impact polymer case that contains the battery and wiring for charging and discharging. The lithium battery can be charged or discharged in any position and is completely non-spillable. It is the maximum sized battery that can be transported in the passenger cabin of a commercial airplane..

For example, when the portable battery is used with your cell-phone car charger attached the Lion Cub Go can run a typical cell phone for 25 times longer than the battery in the phone, or charge a smart phone 15-20 times. Run a 60W laptop power supply for 80 minutes off AC.

Special Features :
  • 120 Watt-hours stored--Can be operated in any position.
  • Portable rechargeable battery with automatic overcharge protection
  • Directly power devices designed to plug into a car power point or cigarette lighter, such as laptops, games, cell phone chargers, GPS, palmtop computers, flashlights, heated clothing, sports score boards, sleep apnea or 12 volt model car chargers.
  • For added flexibility use our regulated DC/DC car power adapters for voltage outputs from 1.5 volts to 24 volts to enjoy unlimited use of electronic products such as games, CD players, walkmans, score boards, video cameras, MINI TVs, and heated clothing.
  • More products can be powered with the 150 watt AC inverter with a three-prong NEMA 5-15 standard AC socket.
  • The USB charging ports can be charged anywhere a cell phone can.
  • Qualified for flight on commercial airlines, but only in the passenger compartment in carry-on luggage.
