6 Powering 12-Volt DC Products
6.1 Connecting 12-Volt DC Products
Portable Power 250 can operate any product that is intended to
run from a vehicle’s lighter socket. Simply insert the DC
product’s plug into the DC Power Socket located on the right
side of the unit. Portable Power 250’s DC Power Socket will
operate any 12-volt DC auto, marine, or other portable 12-volt
product that draws 12 amps or less. Follow these steps after
fully charging Portable Power 250’s battery. (See Section 8).
1. Plug the 12-volt product into the DC Power Socket, and
switch the product on (if required).
2. The 12-volt product will operate until the battery runs out
of power. Refer to step 4 (below) to avoid battery damage
due to excessive discharge.
3. If the 12-volt product is drawing more than 12 amps (or
has a short circuit defect), Portable Power 250’s internal
circuit breaker will switch off power to the 12-volt
product. If this occurs, unplug the 12-volt product and
the breaker will automatically reset after a few seconds.
4. The DC Power Socket does not automatically switch off
when the battery is discharged. To protect the battery
against damage resulting from total discharge, it is
strongly recommended that the AC inverter is switched
on, even when powering a 12-volt product. This will
enable the inverter’s alarm to warn you when the 12-volt
product has nearly depleted the battery. The power used
by the inverter to monitor the battery’s charge level is
negligible.
5. Fully recharge Portable Power 250’s battery as soon as
possible after each use. (See Section 8.)
6.2 Built-in Fluorescent Light
The switch to turn the fluorescent light on is located on the left
side of Portable Power 250, below the fluorescent light. Slide
the switch toward the right and stop at the first setting to
illuminate one tube or the second setting to illuminate both
tubes. With the internal battery fully charged, Portable Power
250 will illuminate both lamps for about 23 hours.
