Features to know about

Recharges Without a Wall Outlet

intelli-start jump starter

Some people buy a jump starter, use it once, and forget to recharge it. Then, it's dead the next time they need a jump. That's why this one charges straight from your vehicle in about 40 seconds. After the jump, it refuels itself using the alternator, so you can pack it away and move on without adding anything to your to-do list.

A Jump Starter That's Easy to Use

There's no special sequence, no buttons to press. Just connect the clamps and start your vehicle. If the battery is too low to detect, you can manually activate override mode. A color LCD screen shows your battery's voltage and alerts you to any faults, so you're never guessing what's going on, even if it's your first time using it.

Strong Enough for Bigger Jobs

This jump starter is compact enough to stash behind a seat, but powerful enough to start gas engines up to 7 liters and diesel engines up to 5 liters. That includes most family vehicles, work trucks, and even light-duty fleet vehicles. It's a great fit for smaller workshops, car lots, or anyone who doesn't want to mess with a bulky rolling unit just to get a vehicle started. And if you need to top off your phone or tablet, there's a built-in USB port for that too.

Built-In Safety That Works in the Background

Mistakes can happen when you're in a rush, or when someone else less experienced wants to help. The clamps are spark-free, so you can't connect them in a way that damages your vehicle. It also protects against short circuits, reverse polarity, over-voltage, and overheating. You don't need to manage any of it. The system handles those risks on its own.

I just got it, and haven't used it yet, but the design and functionality is perfect to carry in my boat for one of those times when the motor won't start. I know it's bound to happen.

I like the compact design - well built and the design to charge other accessories
I know I will be very satisfied

See what our Experts say about this Projecta Jump Starters and Jumper Cables

  • How Does The Portable Projecta Jump Starter Box Compare To NOCO Jump Starter?
    Good morning Lisa! Yes these two brands come up a lot since they are both great quality, name brand options. NOCO makes solid jump starters like the 1,250A # NOC48VR, but one big advantage of Projecta models like the # VX63NR 1,200A and # VX73NR 1,400A is how they handle charging. With Projecta, the unit can recharge itself from the vehicle’s battery + alternator after the jump, which dramatically reduces how often you need to plug it in. Projecta also uses LiFePO4 batteries, which are...

  • Is There A Jump Starter Pack For Cars When The Battery Gets To 0 Volts? Most Jumpers Don't Recognize
    Hey Chris - that’s one of the most frustrating situations out there. I've actually had that happen to me awhile back with a 3-in-1 jump pack / air compressor / light. Projecta units like the # VX73NR 1,400A and # VX23NR 2,000A are designed for exactly that scenario. Their manual override mode can run up to 10 minutes, giving the battery time to build enough voltage to start. Most jump starters don't have the override charge mode, or if they do, it's often under a minute - which just...

  • Best Jump Starter For 2018 Ram 1500 with 5.7 Hemi V8 In Winter
    Hey Brandon! Thanks for the truck details - that helps a ton. For a 5.7L Ram, the Projecta 1,200A jump starter # VX63NR can definitely do the job, but I do recommend stepping up to the 1,400A # VX73NR for full-size trucks. You get more starting headroom, especially if the battery is deeply discharged or it’s below freezing out. The # VX73NR keeps the same easy operation and rapid recharge benefits as the smaller models, just with more muscle. If you ever plan to help someone else with...

  • Is There A Jump Starter Box That Recognizes And Charges A Completely Dead Battery?
    Hey Kevin - that’s an important one, and Projecta actually handles it well. If the battery voltage is extremely low, Projecta units like the 900A # VX95NR, 1,200A # VX63NR, and 1,400A # VX73NR have a manual override mode. That mode lets you force a charge long enough to bring the battery up and start the vehicle. This is another spot where Projecta tends to outperform cheaper jump starters that just shut down and leave you stuck. You still get safety protections - you’re just telling...

  • Comparing Lower Amperage Portable Jump Packs To Higher Amperage Premium Jump Packs For Car Batteries
    Hey Frank! That’s a great question. The Projecta Intelli-Start 3,000A # VX55NR is built for frequent, heavy-duty use. On 12V systems, it’s rated to start gas and diesel engines up to 12 liters, and on 24V systems, it’s designed to handle all standard gas and diesel applications. That makes it a strong fit for fleets, buses, larger trucks, and equipment that smaller jump starters just aren’t comfortable with. If you have a fleet or a shop, or you're a mobile mechanic, this will be the top...

  • Smart And Safe Battery Jumper Pack That Can Be Stored In Glove Box Of Car For Emergency Use
    Hey Hannah - that’s a great priority. Projecta jump starters use LiFePO4 batteries and built-in protection systems to prevent reverse polarity, overheating, and short circuits. Models like the 1,400A # VX73NR and 2,000A # VX23NR are especially popular for that reason. They’re also much more forgiving with dead batteries thanks to the longer manual override feature - something many low-cost jump packs skip entirely. What kind of vehicle will you mainly use it on?

  • Emergency Jump Start That Works With Multiple Vehicles And Battery Types - Top Of The Line
    Good morning Sandra! Thanks for the context - that helps a lot. And yes I agree, some low quality jump starters don't last long at all. If you’re juggling multiple vehicles, especially trucks, stepping up to the Projecta 1,400A # VX73NR or even the 2,000A # VX23NR can make life easier. The # VX23NR adds 24V capability, which opens the door to heavier equipment down the road. That said, many families do just fine with a # VX63NR 1,200A as a do-everything option for cars and light trucks....

  • Good Quality Jump Starter That Will Last More Than A Season Of Heavy Duty Jump Starting And Charging
    Hey Trevor - that’s a very common situation. That “middle ground” is exactly where the Projecta 1,400A jumper pack # VX73NR fits. It’s strong enough for larger gas and diesel vehicles, but still compact enough to keep in your truck without hassle. The big upgrade over cheaper packs is reliability - better safety systems, longer override time for dead batteries, and self-recharging after a jump so it’s usually ready when you grab it. It also comes in a nice storage case that allows it...

  • Durable Jump Pack With Good Battery Life To Jump Start Multiple Dead Batteries In Fleet Of Vehicles
    Hey Mark! Thanks for explaining the situation - that helps a lot. When batteries are truly dead, the big thing to look for is manual override time. The Projecta Intelli-Start 1,400A # VX73NR lets you manually apply power for up to 10 minutes, which gives a dead battery time to wake back up before starting. Most jump starters only allow a short burst - if they allow it at all, which isn't usually enough to bring back a battery that is completely dead at 0v. That longer window is what makes...

  • Heavy Duty Battery Jump Packs For Fleet Of Gas And Diesel Vehicles And Equipment
    Good morning Paula! For mixed use like that, the Projecta Intelli-Start 1,400A # VX73NR is often the sweet spot. It has plenty of power for gas vehicles and lighter diesel applications without stepping all the way into heavy industrial territory. If you ever deal with 24V systems, the # VX23NR would be the next step up. Otherwise, the 1,400A covers a lot of ground comfortably. How big is the diesel you’re working with?

  • Reliable Battery Jump Starter Pack For Hotshotters That Have Lots Of Over The Road Trips
    Hey Eric! Great thinking ahead. For long travel like that, reliability and plenty of amps is what you'll need. The Projecta 1,400A jump box # VX73NR is a solid choice, and if you want even more margin, the 2,000A jump box # VX23NR adds extra power and 24V capability. Both can recover dead batteries, recharge themselves after use (leave hooked up to the battery for a minute or two), and power small devices in a pinch - which is why they’re popular with travelers. I'd opt for whichever...
