Portable 12V Lithium Jump Starter 12000mAh – Marine & Auto Battery Booster

The Seamaster 12000mAh Portable Jump Starter is a versatile lifesaver for any boat owner or driver. Small enough to fit in a glove box or boat storage compartment, this lithium-ion jump starter packs the punch to instantly crank your engine even when your battery is completely dead. Say goodbye to the fear of being stranded on the water or roadside – with this device on board, you can restart your engine within seconds, without needing a second vehicle or external power.

Key features and uses:

• Engine Jump Starting: Designed for gasoline engines up to ~4.0L (in cars, SUVs, boats with outboard motors, personal watercraft) and smaller diesel engines (up to around 2.5L). With a massive 650A peak current, it delivers multiple jump starts on a single charge. Even in cold weather or after long storage, you can confidently fire up your engine. It’s an essential backup for offshore fishing trips, sailing adventures, and road journeys alike.
• 12,000mAh Li-ion Battery: Beyond jump starting, this device serves as a high-capacity power bank. Dual USB ports allow you to charge smartphones, tablets, GPS units, action cameras, and other electronics while on the move. Never be without communication or navigation due to a dead phone battery – whether you’re camping off-grid or anchored in a secluded cove, your devices remain powered.
• High-Brightness LED Flashlight: The built-in LED torch turns the jump starter into a useful emergency light. It features multiple modes: a steady beam for working under the hood or in the engine bay at night, a flashing strobe, and an SOS signal mode for distress situations. For instance, if your boat breaks down after dark, switch to SOS mode to signal for help. The flashlight provides added safety and convenience during nighttime emergencies or repairs.
• Intelligent Safety Protections: The Eval Seamaster jump starter is engineered with safety as a top priority. The smart booster clamps incorporate an advanced protection circuit that prevents sparks and incorrect connections. If you accidentally connect the clamps to the wrong battery terminals, the device will alarm and prevent damage – no harm to the unit or your boat’s electronics. Overcharge protection ensures the internal battery isn’t damaged by prolonged charging, and the unit won’t discharge back into the battery thanks to anti-backfeed design. You can use it with confidence knowing both user and equipment are safe.
• Fast Recharge & Convenience: The jump starter recharges in about 5-6 hours using the included AC charger or a 12V car adapterskroutz.mt. The kit typically comes with various connector tips, a charging cable, and a sturdy carrying case to keep everything organized. It’s ready to grab-and-go whenever you need it. We recommend topping up the charge after each use, or every 3-4 months, to ensure it’s fully ready for an emergency start.

With its compact dimensions and multi-functional design, this portable jump starter is especially valuable for marine use. It provides reassurance on long voyages – for example, if your onboard battery dies overnight at anchor, you can quickly start the engine to recharge it, avoiding being stranded. It’s equally handy on land: boost your car, ATV, snowmobile, or RV without calling for roadside assistance. Investing in this device can save you the cost and hassle of tow services or emergency calls.

Its modern, ergonomic design makes it easy to handle and use on the go. Bright LED indicators let you know the remaining battery level at a glance, so you’ll always be aware when it’s time to recharge.

Whether you’re a yacht skipper, a fishing boat captain, or just driving to the marina, the EVAL portable lithium jump starter is a reliable insurance policy against an unexpected dead battery. Travel with confidence knowing you have a mobile jump-start solution and backup power wherever you go – it’s like having a personal rescue unit in your kit, ready at a moment’s notice.
