An on board charger is a device used to charge a secondary power source—such as a battery—from an onboard generator. It offers an automated charging process that requires no manual intervention, improving both convenience and safety.

Advantages of On Board Chargers

1. Simple installation and maintenance: These chargers are relatively easy to install and maintain, supporting quick and straightforward use.

2. Automation: By removing the need for manual handling, on board chargers provide a hands-free charging solution that enhances safety and user convenience.

3. Cost-effectiveness: Compared to standalone or off-board charging systems, on board chargers often represent a more economical option.

4. Flexibility: They can be programmed with multiple charging profiles, allowing compatibility with various battery types and sizes.

5. Versatility: Designed for use across a wide range of applications, on board chargers offer considerable adaptability.

Disadvantages of On Board Chargers

1. Limited suitability: They may not be appropriate for all applications and in some cases might require a more specialized charging system.

2. Lower efficiency: On board chargers tend to be less efficient than standalone or off-board alternatives, potentially resulting in longer charging times.

3. Upfront cost: Although generally cost-effective in the long run, the initial investment can be a barrier for low-budget projects.

In summary, on board chargers are a popular choice for users seeking an automated and economical charging solution. They are easy to install, maintain, and adapt to various needs. However, they are not universally suitable and may be less efficient compared to other charging options.
