How to Jump Start Your Car Using A Lithium Jump Starter Diagram

The GB50 removes the frustration of having to find or wait for someone to give you a jump. Just attach the clamps to the vehicle's battery terminals, turn the unit on, and start your engine. It's that simple.

User-Friendly Interface with LED Indicators

NOCO GB50 Boost XL Layout Diagram

The GB50 was designed to provide a simple, user-friendly experience. Back-lit LED indicators let you verify that the unit is operating correctly, and they allow it to be easily operated at night. These indicators signal the unit's charge status and alert you to potential performance issues or errors. This allows you to identify if the unit is too hot or cold for operation or detect a reversed polarity connection to a battery.

The touch-button interface allows you to turn the unit on or off or activate the LED work light at the push of a button. The manual override feature can be selected to jump start a deeply discharged battery, below 2-volts. It is important to remember that when this mode is activated, the unit's safety features will be disabled.

Precision Needle-Nosed Boost Battery Clamps

NOCO GB50 Precision Boost Battery Clamps

The Precision Boost battery clamps included with the GB50 are built to fit tight spaces on powersport equipment and remote battery applications. Unlike typical, plastic battery clamps, the Boost clamps are constructed entirely of metal, ensuring maximum conductivity. The clamps are covered with an over-molded plastic housing, which makes them easy to operate even with work gloves on. And the durable 8 AWG silicone cables remain flexible in cold weather so you won't struggle while positioning the clamps.

High-tension springs in the clamps let them tightly grip top and side post battery terminals, and prevent them from slipping during use. The cables connect to the GB50 by plugging them into the available Boost connector port. A protective cover ensures the connection point stays protected when the cables are disconnected from the unit.

High-Intensity LED Work Light with 6 Settings

NOCO GB50 Boost XL Built-in LED Work Light

From jumping a dead battery to changing a flat tire, the GB50 has you covered. The unit has integrated LEDs, with 3 brightness settings, which can be used as a work light in low-light conditions. It can also function as an emergency beacon. Just choose a flash pattern, SOS, blink, or strobe, and then set the unit behind your vehicle to increase visibility and safety.

Portable Charging Power for USB Devices

NOCO GB50 Boost XL USB Charging Port

The GB50 also doubles as a portable power source. The unit has a USB port, which make it easy to charge a smartphone, tablet, camera, wireless headphones, or other device. This is great when you're in an area where power may not be readily available, like a campsite.

NOCO GB50 Boost XL USB Device Charging Times Diagram

The table above provides a quick reference for how many times you can recharge your USB devices before the unit itself needs to be recharged.

Quickly Recharge from USB Power Sources

NOCO GB50 Boost XL Rapid Charge Technology

The GB50's lithium-ion battery can be recharged from 0 to 100-percent in as little as 4-1/2 hours, from a USB power source rated at 2-amps. You can easily charge the GB50 while on the go with the included USB car charger that plugs into a vehicle's aux port, or cigarette lighter socket.

NOCO GB50 Boost XL Charging Times

The Boost Pro can also be charged from any USB-powered port, like a wall charger or laptop, but can take up to 18 hours to completely charge based on the amp rating of the connection.

Rugged Weatherproof Design

NOCO GB50 Rugged IP65 Rated Housing with Port Covers

The GB50 comes with rubber covers that seal the connection points to protect the unit from dirt, dust, and water. With the ports closed the unit has an IP65 rating, which means it can withstand multi-directional, low-pressure water jets and is completely sealed against solid particles like dust or sand.

The housing is made from tough lexan resin that protects the internal electronics against impacts. The unit can handle being dropped, kicked over, and just about anything else the work day brings with it.

Video Transcript for Review of NOCO Jumper Cables and Starters - Jumper Box - 329-GB50XL

Today, we're going to take a look at the NOCO boost XL Ultra Safe 1500 amp lithium jump starter with the LED work light. Now, this is a portable lithium ion jump starter, quickly revives dead 12 volt vehicle batteries, so it's perfect for jump starting diesel cars, trucks, SUVs, boats, motorcycles, even ATVs. It is designed to work with gas engines up to seven liter size and diesel engines up to 4.5 liter size and it is safe for use on engines of any size. It does include everything shown here on the table, the jump starter, the battery clamps, 12 volt car charger, a 40 inch long micro USB cable to charge the internal battery and a nice large microfiber storage bag to carry everything in and a user's guide that'll describe how this operates.Now, this uses a powerful lithium ion battery, which provides up to 30 jumpstart off a single charge. It's rated for over a thousand charge cycles and it'll hold a charge level for over a year with minimal power loss, does have heavy duty precision clamps here when you're jump starting. They are spark proof, they have a coating on them so if they touch each other, you won't get any sparks and it offers reverse polarity protection for increased safety.

It'll show a red LED so when you're plugged into this unit, if you happen to hook these up to the battery wrong, and it's the wrong polarity, it'll have a red LED that'll flash. All you have to do is reverse it and it'll show a white LED, means you're good.The cable on these is a durable silicone cable, maintains flexibility in cold weather conditions. Now, on the jump starter itself, on the top, it'll have a mode button and LED indicators that will let you easily cycle through the charge settings. The separate LEDs will indicate the batteries charge level, reverse polarity air we mentioned, and then charger temperature if it gets too hot or too cold to operate, it'll let you know with an LED. If you turn this on, you can see the four blocks right here, that'll tell you how much power is in your battery.

Right now, we're showing two red blocks so that's 50%. If it was all four lit up, then it'd be a hundred percent.Does have a manual override button right down here that'll allow you to jumpstart a battery below two volts. On this end, it has a USB port that you can charge smartphones, tablets, headphones, or portable speakers. And right here is a USB in that you can use your micro cable there, plug it in and that'll let you charge it through a USB port. On this end, on the corners, it has lights, a built-in rechargeable LED flashlight, has seven different settings.

It'll have three brightness settings and then three emergency settings. I'm going to show you each one here. And to turn it on, you have a light bulb button up here so if you just turn it on, when you turn it on, there will be your brightest, there'll be 50%, there'll be 10%. Then if you hit it again, it'll do the SOS. Hit it again, it will do the blink.

Hit it again, and it's the emergency stroke. And then one more time and it'll be off.So you can go through each one, whichever you need for your application. And this LED flashlight output is about 200 lumens. This is rechargeable with any 12 volt power source or the USB port. It is a nice portable handheld design. You can see it easily stores in your glove compartment, center console, trunk, or toolbox. Application for this is 12 volt lead acid batteries. Starting current, we mentioned, is 1500 amps peak. The internal battery is a 35 watt hour lithium ion battery. The micro USB input on this side that you'll charge with is 2.1 amps. USB output that you can charge your phones with is 2.1 amps. Operating temperature for this jump starter is negative four degrees Fahrenheit to 122 degrees Fahrenheit.And the last thing I do is just want to give you some measurements on this. Overall length of it, it's right at seven and three quarter inches long, height of it is about two inches tall and the width on it, it's about three and seven sixteenths inches wide, and the weight is only about 2.7 pounds. But that should do it for the review on the NOCO Boost XL Ultra Safe 1500 amp lithium jump starter with the LED work light..

I have used my jump starter several times in the past year. It has worked every time, and holds its charge very well. Carry it in my car at all times. Much better than jumper cables.


I LOVE this battery pack! Holds a charge for months during non-use. Jump starts quickly.


Used several times to jump other peoples cars. Used once to charge phone. Works great
