It is the difference between finishing the job and packing up early.\u003c\/strong\u003e The Jump 1500 Extra Battery is 1548 watt-hours of lithium iron phosphate storage that docks into a power station you already own: the JUMP 1500X, the JUMP 1800, the JUMP 2200. It is not a power station itself, and it will not run a kettle on its own. It is the second reservoir, the one you add after the first one turns out to have been a first draft.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003e\u003cstrong\u003eLithium iron phosphate is the chemistry you choose when the battery has to live in a van, a shed or a truck bed.\u003c\/strong\u003e LiFePO4 holds its structure through deep discharges that would age a lithium-ion pack, and it does not carry the thermal runaway profile that makes insurance inspectors ask questions. That is why this pack ships with CE, FCC, RoHS and UL certification rather than a sticker and a promise. Paired with the host station it delivers 1000 to 1500 watts of output, and it accepts up to 200 watts on the input side, which is a deliberate overnight fill rather than a fast top-up.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003e\u003cstrong\u003eGeometry matters as much as chemistry.\u003c\/strong\u003e The case is 36 by 27 by 28 centimetres and weighs 14.87 kilograms, sized so one person can move it without a trolley and so it stacks beside the station instead of on top of it. Charging is rated from 0 to 55 degrees Celsius and discharge from -20 to 55, which means the pack can stay in the vehicle over a cold night and still be useful in the morning. Home energy, jobsite power and weekend off-grid work are all the same problem: you need more hours than the first battery had.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#555;margin:0 0 6px;\"\u003e\u003cem\u003eThis is not a spare battery.
