Schumacher? RoadStart? Emergency Jump Starter 12/24V 4600 Peak Amps – DEKRA Approved

Manufactured with professional grade, high performance AGM battery, produced in the USA and specially formulated to jump start vehicles. The only range of DEKRA approved emergency jump starters on the market. Supplied with an automatic maintenance charger that features patented microprocessor controlled speed charging, with thermal runaway protection. This means that unlike other booster packs, the unit can be left safely on charge continuously ensuring it is always ready for use. Fitted with an isolating rotary on/off switch and features a 2-function digital display showing the internal battery level and the vehicle battery voltage. Fitted with a 12V accessory socket and a single 2.1A USB port ideal for charging mobile phones or tablets. A fusible link integrated in the output cable provides surge and spike protection, preventing damage to delicate and sophisticated vehicle electronics, as well as the booster. The heavy-duty clamps are manufactured with a braided link between each jaw for maximum power transmission, whilst also being curved allowing easy access to awkward or hard-to-reach battery terminals. Easy cable and clamp storage ensure the unit is compact and tidy when not in use. Audible warning system (AWS) to advise operator if the unit has been turned on for too long without being connected to a battery and for reverse polarity. Features a direct ventilation system from the batteries, this is in place so if the unit was inadvertently attached to a 24V vehicle whilst in 12V mode, which would cause the batteries to ?gas?, the gases would be vented directly out of the casing via a ?Whistle? outlet, warning the user of a potential issue.
