Plug-in power cord question

[LarryT]

I purchased a 12V Rechargeable Cooler/Warmer for use on airplane camping trips. Unfortuantely I outsmarted myself. Unit was purchased from a department store liquidation sale and was a cleverly repackaged "open box" that was missing the cigarette lighter power adapter. No returns and no cooperation from the manufacturer when I tried to buy a power cord from "customer service."

Not wishing to do something really stupid - like overcharging the battery and starting an in-flight fire, I thought I would ask one of the VAF electrical experts.

Battery specs:

Orema Power Co., LTD. Model UN6-6 6V6.0Ah Valve regulated rechargeable sealed lead battery

Constant Voltage Charge:
Cycle use: 7.25 7.45V
Standby use: 6.8 - 6.9V
Initial current: less than 1.5A



Can someone recommend a plug-in power cord? (I notice the power cord for my AV8OR says 5V 1.5A, so it must step down the the car or plane voltage within the device)

Thanks,

Larry
