iTechworld PS3600 Portable Lithium Power Station + EB3640 Expansion Battery Kit

Introducing the iTechworld PS3600 Portable Lithium Power Station + EB3840 Expansion Battery Kit, the complete power package for anyone serious about off-grid living, remote work or long-term home backup. Whether you're travelling full-time, prepping for blackouts or powering a remote site, this kit delivers high capacity, fast charging and unmatched reliability.

At the heart of the system is the PS3600 PRO, featuring a powerful 300Ah Lithium LiFePO4 battery with 3840Wh of storage. It includes a 3600W pure sine wave inverter, capable of running everything from air conditioners and washing machines to coffee machines and laptops. Plug in your 12V fridge and you’re good to go for up to two weeks on a single charge.

Paired with the EB3840 Expansion Battery, the system jumps from impressive to exceptional. Add one battery to double your capacity to 7680Wh (600Ah) or two to reach a massive 11,520Wh (900Ah). That means you get more runtime, more appliance support and true peace of mind, wherever you are.

Recharging is fast and flexible. Use mains power, solar panels (just bypass the regulator), car input or generator. With the Super Charge algorithm, the PS3600 can go from flat to fully charged in just hours. And thanks to pass-through charging, you can still use all outputs while it’s plugged in. The built-in UPS (Uninterruptible Power Supply) with a 10ms switch-over keeps your gear running seamlessly during outages.

It’s also safe, efficient and easy to use. Both the PS3600 and EB3840 feature full battery protection covering over-charge, over-discharge, short circuits, over-current and overheating. The system also comes with an informative LCD screen, multiple USB-C PD and Quick Charge ports, 12V sockets and more.
