      Q:Do you have to connect it to the Vehicle battery to jump start a vehicle or can you just plug it into the vehicle charging port. Because some batteries terminal are hard to connect to for some people
      by|Jan 19, 2024
      1 Answer
      Answer This Question

      A:  The NOCO Boost Jump Starter needs to be connected via the battery terminals/posts (the negative clamp can connect to a negative ground on the vehicle chassis rather than the post if necessary). There is no way to jump start the vehicle from the 12V port inside of the vehicle.

          Very happy to have this dependable unit
          Great product works on our ford 350 diesel 7.3 L truck, Ford Ranger 4.0L and multiple other trucks and cars for our family. Came in great looking packaging with 12 volt car charger and USB charging cable. Unit has ports to plug in your phones, iPad and other devices. Light on unit is great idea for night time connections and repairs. Unit charges much faster than older models. Note must have car/truck running to properly fully charge unit. I was disappointed that unit didn't come with a house AC charging system, NOCO website has the house charger U65, 65W USB-C Charger with carrying case. Charges up to five times faster than traditional USB wall or car chargers. Cost about $ 70.00 plus shipping. That is why it didn't give it 5 stars. Very happy to have this dependable unit with me when traveling or on that very cold morning the car or truck will not start.

          Don't Call A Tow Truck For A Jump Start
          This is a very nice piece of equipment to have. I have used it at least a half dozen times and it performed perfectly. It's small, powerful and easy to use. It's been used on both a cars and SUVs. No more cumbersome bulky jumper cables. Had to call a tow truck once, they carried the same brand (different model) on the truck, so I bought this one.

          No good
          after using it twice. My NOCO GBX75 2500A tried to recharge the battery but I never charged, I tried with different chargers and the result was the same, I never charge... It's a shame.

            All good, except an 120V UBS converter was not included. No way to recharge without additional purchase. Boo!!!
