The PulseTech® SP-12-OBD-A 12-Watt Temporary Solar Charger restores and maintains the normal loss of 12V lead-acid battery power on cars, small trucks and other outdoor equipment. It can be installed and removed in minutes. The solar panel replaces the power loss from electrical accessories that occurs in seldom used outdoor vehicles even when the ignition is switched off. It's great for vehicles with lots of accessories and high parasitic loads. Pulse Technology reverses sulfate crystal buildup on the battery plates. Clean batteries recharge faster, accept a full charge and work at max power. Connect the charger directly to the vehicles OBD2 port and the solar panel, attach the panel to the interior windshield with suction cups.

The 12W solar panel measures 12.41"Lx9.85"Wx0.2"H. Includes a 3' box-to-lug wire and 17' box-to-panel wire.

The SP-12-OBD-A is a higher watt version of the SP-10-OBD-A 10W Solar Charger.



This 12-Watt SolarPulse Temporary Charging System provides a full 12-Watts of power in a compact, durable 12.41"L x 9.85"W x 0.2"H solar panel and is ideal for use with 3-4 12V batteries connected in parallel. The solar panel attaches to the interior windshield with the included suction cups and plugs directly into the OBD port. The set up allows for easy installation and removal in seconds and ensures batteries remain in peak condition no matter how long the vehicle sits unused outside.

Like all SolarPulse models, the SP-12-OBD-A utilizes our unrivaled solar charging system combined with our patented optimized high frequency pulsing circuit, Pulse Technology, to ensure batteries start when needed dramatically reducing the need for jump starts. Pulse Technology reverses the naturally occurring process of battery sulfation - the main cause of battery failure. This allows batteries to accept, store and release maximum power all the time extending battery life three times.

If you've used solar chargers before, you know it's important to choose the right solar panel for the amount of power you need and the size and place of the mounting location. In the past to get the power you need, you had to struggle with panels that are too big, too bulky and too fragile. With SolarPulse, you get the power you need with the most installation options for your outdoor vehicles and equipment. SolarPulse's higher efficiency, higher quality monocrystalline cells pack more power per square inch and have a longer life than standard amorphous ''thin film'' cells. That means you get the power you need in a sturdier, smaller-sized solar panel. Instead of a breakable glass coating, SolarPulse's solar panels are protected with a clear polyurethane plastic coating that makes them virtually indestructible and impervious to weather aging and damage from bumps and knocks.
