Goal Zero Sherpa 100AC: The Ultimate Power Solution

The Goal Zero Sherpa 100AC acts as an all-in-one power bank that serves as a bridge for camera charging. By storing energy from the house battery system during the day, it provides a stable AC or DC output for camera chargers when you want to avoid tapping into the main inverter. It is essentially a battery for your batteries.

This device is particularly useful for those who spend time away from the van with their camera gear. It allows you to charge your camera batteries inside your hiking pack or a remote workspace without needing to be tethered to the vehicle’s electrical system. It offers a level of freedom that stationary chargers cannot match.

While this is an expensive, high-capacity solution, its versatility is unmatched. It is not just a charger; it is a portable power station that safeguards your gear against unexpected energy shortages. For long-term nomads who value portability and peace of mind, the Sherpa 100AC is a cornerstone of a mobile power setup.

How to Choose Your Van Camera Charger

When selecting a charger for your van, the most important factor is the input method. Look for chargers that accept USB or 12V DC input directly. This allows you to bypass the van’s inverter entirely, which saves significant power because inverters consume energy even when they aren’t actively pushing a large load.

Size and mounting capabilities are also critical considerations. A charger that can be flush-mounted to a wall or secured inside a cabinet will prevent gear from rattling around during travel. Always check the physical footprint against your available storage space, keeping in mind that you may need room for spare cables.

Finally, consider the heat dissipation of the device. Vans can get hot in the summer, and charging lithium-ion batteries generates additional heat. Select a charger with adequate ventilation or one that is rated for high-ambient-temperature environments to ensure both the charger and your expensive camera batteries stay within safe operating limits.

Powering Chargers: 12V Sockets vs. Inverters

The golden rule of mobile power is to utilize DC power whenever possible. 12V sockets (cigarette-style or USB-C PD) are far more efficient than converting your battery power to 110V/220V AC through an inverter. Inverters have an idle draw—a “tax” they charge just for being turned on—that can drain a house battery over time.

If your camera charger comes with a wall plug, search for a 12V adapter specifically for that unit, or use a high-quality USB-C Power Delivery (PD) charger. USB-C PD is the modern standard for power delivery and can often handle the requirements of multiple camera chargers at once. This approach simplifies your wiring and maximizes the lifespan of your house battery bank.

Only use an inverter for camera charging if you have no other choice, such as when using legacy gear that lacks a DC-compatible charger. Even then, try to group your charging tasks together to run the inverter for a shorter, more intense period rather than leaving it on all day. Efficient energy management is a learned habit that preserves your electrical system’s longevity.

Sizing Your System for Camera Charging Needs

Start by calculating your total daily watt-hour consumption for all cameras and accessories. A standard mirrorless camera battery typically sits between 10 and 15 watt-hours. If you charge three batteries a day, you are looking at 45 watt-hours of demand, which is easily managed by most house battery banks.

However, if you are also running lights, monitors, and laptops, these demands add up quickly. Always size your house battery bank and solar array with a 20% buffer beyond your maximum calculated need. This buffer accounts for cloudy days, inefficient wiring, and the natural degradation of batteries over time.

Do not overlook the wire gauge when installing 12V charging points. Charging equipment draws steady, sustained current, and undersized wire can lead to voltage drop and excessive heat. Use a wire sizing calculator to ensure that the power reaching your charger is clean, stable, and safe, regardless of how far the outlet is from your bus bar.

Van Life Camera Charging: Frequently Asked Questions

Can I leave my camera batteries on the charger while the van is driving? Yes, provided the charger is securely mounted and the house battery system is regulated. Ensure the charger is not in direct sunlight and has proper airflow to manage the heat generated by both the charging process and the van’s interior.

Why is my camera charging so slowly in the van? Slow charging is usually a result of voltage drop or an underpowered USB port. Ensure you are using a high-output USB-C Power Delivery port rather than a standard 1A USB-A port. High-quality cables are also essential, as thin, cheap wires struggle to transmit the necessary amperage.

Is it safe to charge camera batteries while the van is turned off? It is perfectly safe, provided your charger is wired directly to your house battery bank, not the engine starter battery. Never charge gear from the starter battery unless you have a dedicated isolator; doing so risks leaving you stranded with a dead engine battery.

Properly outfitting your van for camera charging requires a balance between efficiency and utility. By choosing the right equipment and prioritizing DC power, you ensure your gear remains ready for the next adventure without straining your electrical system. A well-designed charging setup is a quiet but vital component of any successful mobile lifestyle.
