Jackery unveils the Explorer 300D in Australia, featuring a stripped-back design lacking an AC inverter to enhance runtime and reduce noise, targeting users with USB-C equipment and remote operators.
Jackery is bringing a stripped-back portable power station to Australia, unveiling the Explorer 300D at the National 4×4 Outdoors Show in Melbourne from August 21 to 23. The unit will go on pre-order on the first day of the event at an early-bird price of AUD 299, compared with its regular Australian price of AUD 449. The company is positioning the device for users who primarily charge modern USB-C equipment rather than appliances that still need a wall socket.
The central design choice is the absence of an AC inverter. Jackery says that removing the inverter avoids the energy losses created when battery power is converted from DC to AC and then back again inside the device being charged. In practical terms, that should improve runtime for laptops, cameras, mobile routers and similar gear, while also allowing the unit to run fanlessly and in complete silence. The Explorer 300D offers three USB-C ports, one USB-A port and a 12V car socket, with a peak output of 300W.
Its top USB-C port supports 140W USB Power Delivery 3.1, which is enough to fast-charge most current laptops at close to their maximum supported rate. Jackery also includes an integrated 140W USB-C cable that doubles as the carry handle, a small but useful detail for people who travel with compact power kits. The company says the handle is rated to 10kg, so it is intended to function as a real grip rather than just a design flourish.
Inside, the Explorer 300D uses a 288Wh lithium iron phosphate battery, or LiFePO4. Jackery says the pack is rated for more than 4,000 charge cycles before dropping to 70 per cent of its original capacity, which is in line with the chemistry’s long-life reputation. The company also says its ZeroDrain system can preserve 99 per cent of charge after a year in storage, while the battery management system protects against overcharging, deep discharge, short circuits and temperature extremes.
The compact form factor is part of the appeal. Jackery says the Explorer 300D weighs 2.5kg and is up to 64 per cent smaller than typical 300Wh portable power stations, a claim echoed in product listings from Jackery and retail partner B&H. The company is also highlighting Starlink Mini compatibility, saying the unit can keep the terminal running for up to 10 hours, which may make it useful for overlanders, field crews and remote content creators. Jackery is backing the launch with broader discounts across its Australian range, and says the Explorer 300D carries a three-year warranty with a two-year extension available.
