Ring has introduced its most advanced jumpstarters to date with the Ultraboost range. These latest additions to its compact Lithium JumpStarter range have an exciting new feature, the Ultraboost button, which when pressed delivers enough power to start completely flat batteries, as low as 0.7 of a volt. The jumpstarters in this offering also have a unique design created and engineered by the team at Ring that sees the charging leads connect on the end, not out of the side like most others in the market, creating a seamless design. There are three models in this range, all differing in power and capabilities. The RJS030 is Ring’s most advanced jumpstarter, the Ultraboost 1500A is capable of jumpstarting vehicles with up to 6L petrol and 3L diesel engines, which means it’s suitable for most 12V cars, vans, SUVs and LCVs.
