Key specifications

You want clear numbers so you can compare gear quickly, and these are the headline specs to pay attention to. The table below summarizes the most important technical details so you can see what you’re getting at a glance.

What’s included in the box

You’ll typically get the charger unit itself with the attached input and output cables and an integrated handle for carrying. Check the product listing for specific accessory details like connector types or mounting hardware, because those can vary by seller or region.

Design and build quality

You’ll notice the charger’s aluminum alloy die-cast shell right away, which gives it a rugged and industrial feel. Because it’s designed for utility vehicles and outdoor equipment, the enclosure prioritizes durability and resistance to environmental stress.

Materials and construction

The aluminum alloy housing isn’t just for looks — it’s meant to provide impact resistance and improved heat dissipation compared with plastic enclosures. You can expect the case to resist dents and maintain structural integrity if it’s bumped during routine handling.

Portability and handle

The integrated handle is a small but useful feature; you’ll appreciate being able to pick the unit up and move it between storage areas, vehicles, or charging stations. The overall weight is dictated by the robust construction and cooling system, so while it’s portable, it’s not featherlight.

Ingress protection and durability

Rated IP65, this charger is built to resist dust ingress and withstand water jets, so you can use it in a garage, on a boat, or in somewhat wet conditions without immediate worry. That rating doesn’t mean it’s submersible, so avoid full immersion and prolonged exposure to heavy rain.

Charging performance

When you want fast recharge times without sacrificing battery health, the charger’s 18A current and 900W peak power make a meaningful difference. You’ll see substantially reduced downtime for vehicles and equipment that need frequent cycling.

Charging speed and capacity

Expect a full charge of a 30AH pack in roughly 1.2 hours, a 50AH pack in about 2 hours, and a 100AH pack in approximately 4 hours based on the manufacturer’s testing. Those numbers assume the battery is in healthy condition and the charging environment is within recommended temperature ranges.

Efficiency and power

A charging efficiency of ≥ 93% is strong for a unit in this class, which means less wasted energy and lower heat generation during normal operation. You’ll lose minimal energy as heat, and overall power draw from your source will mostly be converted into stored battery capacity.

Charging algorithm and BMS interaction

The charger uses standard multi-stage charging logic and is designed to cooperate with internal BMS (battery management system) features. You’ll get charge cut-off when the battery reaches full voltage, and compatible BMS-protected packs should prevent overcharge situations when the systems communicate properly.

Safety features

You’ll feel more secure using a charger that layers protections to prevent common problems like overvoltage, short circuits, and overheating. This unit bundles multiple protections to reduce risk of damage to both the charger and the battery.

Six safety protections

There are six primary protections: input under/over voltage, charger overheat protection, output no-load protection, output short circuit and reverse connection protection, and output over current/over voltage protection. You’ll find these combined protections helpful whether you’re charging in a workshop or outdoors, and they’re particularly useful if you run multiple charging sessions per week.

Cooling and thermal management

The active cooling fan helps keep internal temperatures in check during heavy-duty charging cycles, which improves longevity and consistency. You’ll hear the fan when it’s working; that’s normal and indicates the unit is actively managing heat.

IP65 and drop resistance explained

IP65 ensures dust-tight protection and protection from low-pressure water jets. The aluminum die-cast shell improves mechanical resilience so the charger can withstand occasional knocks or drops that happen in a busy garage or on a job site. You’ll still want to avoid rough handling, but the construction reduces vulnerability.
