The Dometic PerfectPower DCC 1212-10 DC-DC Battery Charger Keeps Your House Battery Charged From the Alternator While You Drive
The Dometic PerfectPower DCC 1212-10 DC-DC Battery Charger is a 12V to 12V DC-DC charging converter with a 10 amp charge current. It charges your house battery from the vehicle's alternator while you drive.
It is built for modern vehicles with smart, variable-voltage alternators, which often don't hold the voltage a house battery needs. It also suits installs where long or thin cable runs would otherwise leave the battery undercharged. Go Power calls the 10 amp model a good fit for small vans and trucks with a single auxiliary battery.
Dometic PerfectPower DCC 1212-10 DC-DC Battery Charger Features
Made for Smart Alternators
The charger accepts 8 to 16 volts at its input and charges at 13.2 to 14.7 volts, up to 10 amps or 120 watts. Go Power says this keeps the house battery full on Euro 6 and other variable-voltage charging systems.
IU0U Charging Set From Outside the Case
IU0U charging for lead-acid, gel and AGM batteries is set with DIP switches on the outside of the housing, so there's no need to open the case. The switch block sits on the output end, next to the covered output terminals.
Optional Temperature Compensation
Add the optional temperature sensor and the DCC 1212-10 charges with temperature compensation.
Stable Output for Sensitive Devices
Residual ripple stays under 50 mVeff at rated current. Go Power says the output is stable enough for the charger to double as a constant power supply for sensitive devices.
Turns On With the Engine
The charger switches on from a D+ signal, an alternator signal (terminal 15) or a switched input. That way it only draws from the starter battery while the engine is running.
Efficient and Protected
Efficiency reaches up to 90%. A high-voltage shutdown and other built-in safeguards protect the charger.
Real-World Applications
Small vans. Charge a single auxiliary battery from a smart alternator every time you drive.
Trucks. Keep an auxiliary battery in a truck charged on the road without drawing from the starter battery while the engine is off.
Long cable runs. Charge a house battery at the end of a long or thin cable run that would otherwise leave it undercharged.
Practical Comparison
DCC 1212-10 Versus a Direct Alternator Connection
With a direct connection, the house battery only gets the voltage the alternator and cable deliver. Go Power notes that smart alternators often don't hold the voltage a house battery needs, and long or thin cables can leave it undercharged. The DCC 1212-10 takes 8 to 16 volts in and charges at 13.2 to 14.7 volts with an IU0U profile.
DCC 1212-10 Versus a Shore Power Battery Charger
A shore power charger needs a 120V AC hookup. The DCC 1212-10 runs from your vehicle's 12V system while the engine is running, so the house battery charges on travel days without plugging in.
Buyer Guidance
Battery Type and Charging Voltage
Go Power lists lead-acid, gel and AGM batteries for this charger, with a charging voltage of 13.2 to 14.7 volts at up to 10 amps. Check that your battery maker's recommended charge voltage falls within that range before you install it.
Mounting and Wiring
The housing measures 153 x 180 x 73 mm (6.02 x 7.09 x 2.87 in), width by depth by height, and weighs 1.25 kg (2.76 lb). Mounting flanges with screw holes sit at each end of the base. It is rated to operate from -20 to +50°C (-4 to 122°F). Plan for a D+ signal, a terminal 15 alternator signal or a switched input to turn it on. Cable and fuse sizes aren't part of these specifications, so plan them with the DCC series installation and operating manual or ask our team.
This May Be A Good Fit If
- Your vehicle has a smart, variable-voltage alternator
- You charge a lead-acid, gel or AGM house battery
- Your house battery sits at the end of a long cable run
- You have a small van or truck with a single auxiliary battery
Common Questions
Does It Work With a Smart Alternator?
Yes. It is built for vehicles with smart, variable-voltage alternators, including Euro 6 charging systems, and it accepts 8 to 16 volts at its input.
Will It Drain My Starter Battery?
It switches on from a D+ signal, a terminal 15 alternator signal or a switched input, so it only draws from the starter battery while the engine is running.
Can It Charge Lithium Batteries?
Go Power lists lead-acid, gel and AGM batteries for this charger. Lithium isn't on that list, so ask our team before you use it with a lithium battery.
Is the Temperature Sensor Included?
The temperature sensor is listed as optional, not as part of the charger. Connect one for temperature-compensated charging.
