Our verdict

A four-in-one roadside unit that jump starts, inflates tires, charges devices and lights the scene. Its listed diesel engine size is modest, so larger diesel trucks need a stronger starter.

Overview

Jumping a dead battery, topping up a tire and charging a laptop all happen from this HALO unit. It combines a jump starter, air compressor, power bank with AC outlet and an LED floodlight in one carry case design.

Four emergency tools in one box is the reason it suits a trunk kit. The AC outlet removes the need for a separate inverter. Its listed range covers mid-size gas engines and only smaller diesels.

Who it's for

Drivers of cars, SUVs and gas trucks who want one device for common roadside problems will get the most use. Owners of large diesel engines should look at a higher-rated starter.

Pros and cons

Pros
  • Jump starts, inflates and powers devices
  • AC outlet for laptops
  • Floodlight for night use
Cons
  • Limited diesel engine size
  • Bulkier than a pocket jump pack

Performance notes

Jump power comes from the internal battery delivering high current through spark-proof cables, while protection circuits guard against wrong connections. The compressor and AC outlet draw from the same battery, so heavy use reduces jump capacity. Recharge after each use.
