About this item

  • 【3-SECOND FORCE START – 8000A FOR SEVERELY DEPLETED BATTERIES】The X8 battery jumper starter portable features an advanced Force Start function that helps revive batteries that are too low for many ordinary jump starters to recognize. It delivers a true 8000A peak current to bring severely depleted 12V batteries back to life in about 3 seconds. This powerful car jump starter and car jumper starter portable supports all 12V gas and diesel engines in cars, SUVs, trucks, motorcycles, boats, and RVs. Compared with many smaller jump starters, this portable jump starter gives you stronger, more confident starts when your vehicle will not crank.
  • 【HOT & COLD WEATHER READY – -4°F TO 140°F】Rated for extreme conditions from -4°F to 140°F, this portable car jump starter works as a dependable car jumper in winter cold and summer heat. Whether you keep it in your trunk as a jump box or rely on it as a car starter jump box for long road trips, the X8 is designed to deliver reliable power in tough weather and roadside emergency situations.
  • 【HEAVY-DUTY METAL CLAMPS & SMART JUMPER CABLES FOR CAR】Enhanced heavy-duty metal clamps provide a stronger, more stable grip on the battery terminals, helping each start feel more solid. The thick, reinforced handles are anti-slip and drop-resistant for long-term durability. Paired with smart jumper cables for car, the X8 jump starter includes robust jumper cables that give you a secure connection for every use.
  • 【LIGHT & BUZZER GUIDANCE – INTUITIVE JUMPER BOX FOR CAR BATTERY PORTABLE】Smart clamps with indicator lights and buzzer alerts guide you step by step: green flashing for standby, green solid for ready to start, and red flashing or solid plus buzzer for high temperature, reverse connection, or short-circuit warnings. This design turns the X8 into a very clear jumper box for car battery portable, so you can use it as a jump box for car battery or compact jumper box without guesswork.
  • 【3-MODE LED FLASHLIGHT & DUAL USB POWER BANK – JUMP PACK FOR CAR BATTERY】The built-in LED flashlight offers three modes: steady light, strobe, and SOS, ideal for night-time vehicle checks or outdoor use. The X8 also functions as a jump pack for car battery and a daily-use power source, with two USB-A output ports: one USB-A QC3.0 fast charge port (5V/9V/12V) and one 5V/2A USB-A port. Easily charge phones, tablets, cameras, and more while on the road.
  • 【FULL KIT INCLUDED & 2-YEAR WARRANTY】Ideal for drivers searching for an arrancador de batería para auto or a cargador de bateria de carro portatil, the X8 kit includes everything you need: 1× X8 Jump Starter, 1× Smart Jumper Clamps, 1× Carry-on Toolbox, 1× USB-A to C Cable, and 1× User Manual. Backed by a 2-year warranty, it is a practical choice to keep in your vehicle for daily driving and unexpected battery problems.

Car battery Jump starter

I have not only had to use it to jump start my vehicle but my son's vehicle also worked great for that and I have also used it to charge my phone several times. It's a very nice tool to have when you need it. Read more

not bad, could be a little better though

this is a fantastic external charger for charging many objects like a phone or tablet. Unfortunately I wouldnt trust it as my fail safe back up for starting the car because it must remain above 80% to be able to do that. It can lose that much power just sitting, especially in colder months. I keep it with me anyway because as I said tis still useful and if it is above the threshold for engine starting then great. The light is a great touch too, very helpful for changing a tire or when stuck along the roadside wanting to be visible. Over all I am glad I picked this up. Read more
