GB40 Vs. GB50 Vs. GB70: What do they share?
All of the models feature similar battery clamps, which are color-coded – red for the positive terminal and black for the negative terminal. They also feature a LED flashlight with seven different light modes, SOS, and emergency strobe capabilities. The purpose of the LED flashlight is to help you perform repairs in dark environments, under the bonnet, and at night.
Moreover, the NOCO jump starters USB ports integrated into the system. They all have a micro-USB port used for charging the devices. They also have a USB-out slot for charging other devices such as phones, smartphones, tablets, cameras, and earphones.
Safety and protection systems
NOCO GB50, GB40, and GB70 designs come with a spark-proof protection system to prevent the devices from giving off any sparks thus won’t supply power to wrongly connected wires. On top of that, they are all IP65 rated for dust and splash protection, meaning that they can survive water and dust splashes but can’t withstand submersion in either.
Last but not least, the NOCO jump starters come with reverse polarity protection. Reverse polarity protection prevents you from accidentally killing your vehicle’s battery by wrongly connecting the cables.
GB40 Vs. GB50 Vs. GB70: What makes them different?
The NOCO jump starters have the same general design based on the outer shell design (rugged and great-looking), port placement, wiring, and the accessories in the shipment package. However, they differ slightly in a few of the features available, the corresponding effector button placement, and design layout.
The NOCO GB50 is an upgraded model of the NOCO GB40 made in 2019; the NOCO GB40 initially launched in 2010 with later releases in 2015. As you can see from the images below, they differ slightly by introducing a HOT LED indicator and a COLD LED indicator.
They also differ in dimensions, with the GB40 coming in at a measurement of 6.57 x 3.15 x 7.72 Inches. The NOCO GB50 comes in at a measure of 7.7 x 3.4 x 1.9 Inches.
The design elements and accessories that come in all of the packages include; heavy-duty precision battery clamps, a 12V car charger, a micro-USB cable, a microfiber storage bag, a user guide warranty information. The NOCO GB70, on the other hand, comes with two separate car charger adapters – an XGC 12V female adapter and an XGC 12 V male adapter. Moreover, GB70 comes in at a 6.0 x 2.5 x 8.6 Inches measurement and lacks a ‘Light Mode Button.’.
A huge contributor to the selection of a jump starter is weight. The GB40 weighs 2.45lbs (1.11kg), GB50 weighs the same as GB40, and GB70 weighs 4.18lbs (1.9kg).
The NOCO jump starters’ design pays attention to portability and ease of mobility. As seen above, their dimensions and weight give these models the small design specifications to fit in small storage spaces and get carried around without effort.
NOCO GB40 is significantly smaller than GB70 but negligibly so when compared to GB50. GB50 is just 1.1 inches longer than the GB40 with negligible margins in terms of width and height.
GB40 features a flashlight with a strength of 100 lumens. The power is lower compared to the 200 lumens you get with the GB50. GB70 features a heavy light output of the onboard LED flashlight rated at 400 lumens.Check Price at Amazon
The GB70 is the only model among these that comes with a 36W/3A fast-charging option. The other models lack any form of fast charging, making them less appealing to the GB70; however, this difference gets counteracted because GB70 has a bigger battery capacity rated at 56 Watt-Hour.
The table below showcases the various specifications for all the models and how they match each other.
These NOCO models come with many features, most of which are necessary for most vehicles; however, some features, especially those on the GB70, are reserved for heavy-duty vehicles. The majority of vehicle owners will be delighted with the elements the GB40 offers and maybe consider the GB50 for added versatility.
NOCO GB40 can provide a starting (peak) current of 1000Amps to a 6.0-liter gas engine or a 3.0-liter diesel engine. That power delivery can jump-start 20 cars before power depletion. That type of power makes it sufficient for powering up batteries in cars, some trucks, RVs, and some boats.
On the other hand, the NOCO GB50 comes in at a peak current delivery of 1500 Amps enough to juice up a 7.0-liter gas engine or a 4.5-liter diesel engine. That power delivery can jump-start 30 cars before power depletion.
Finally, the GB70 stores a power of 2000Amps. It can deliver its total capacity to an 8.0-liter gas engine or a 6.0-liter diesel engine. That power delivery is capable of jump-starting 40 cars before its battery power gets wholly depleted.
Not all jump starters are the same, which is to say that your vehicle will need a precisely calibrated jump starter that suits its needs. Different cars require different numbers of Amps to start, which will determine the jump starter size you use. Its displacement and horsepower greatly determine the number of amps needed for a vehicle. Most cars will get away using a 1000Amps jump starter, but others, such as heavy-duty trucks and boats, will need a 2000Amps jump starter. It’s, however, crucial to remember that the engine capacity specs for these models are just estimates; this is because factors such as compression ratios come into play.
Picking any of these models will involve identifying your engine’s capacity and horsepower—other factors such as the jump starter’s battery capacity, starting current, and charging times.
NOCO GB70 is the most powerful of all three. It is highly overpowered for most vehicles on the road with its 56 Watt-Hour Lithium-Ion battery and 2000Amps of starting current delivered in 3 seconds. It is suited for large engines found in trucks, tractors, and boats that can’t jump-start using the less powered GB40 and GB50. They are also suitable for jump-starting a garage full of dozens of vehicles and high-powered SUVs.
Apart from their primary objective, the NOCO jump starters get used for charging other devices such as smartphones and tablets. The GB70 takes this up a notch with its capability of powering 12Volt devices such as fans and power inverters. Moreover, the GB70 offers another charging input of 36W/3A fast adaptive charging, providing twice the amperage as the GB40. It means that you can charge GB70 twice as fast as the GB40.
How long do they take to charge my car fully?
The charge LEDs are battery level indicators on the models used to denote the amount of charge available in the jump starters. The battery levels get divided into four-LED array units, with each unit having a percentage of 25. The largest unit is green for a higher battery level, the following unit is amber for 25% less battery, and two red units showcase the remaining 50%. Mechanics recommend charging the device once there is only one red battery indication.
The charging time for GB40 through USB charging is 3 hours at 2A, 6 hours at 1A, or 12 hours at 0.5A. On the other hand, GB70 can be charged either through USB or through a 12V fast charge (36W). For USB charging, it takes 7 hours at 2A, 14 hours at 1A, and 28 hours at 0.5A, while on a 12V fast charger, it takes 2.3hours at 3A. GB50 charging times range from 4.5 hours to 18 hours, with 4.5 hours achieved at an optimal 2A.
The NOCO jump starters may have to be connected to your dead battery for about 30 seconds before you see any results.
The GB50 is better than the GB40 in every aspect, except for the price. GB40 retails for a cost of $99.95 while GB50 goes for $149.95. GB70 is the most expensive (going for $199.95) but is better for heavier vehicles.
For a more versatile, powerful, functional, and full-proof application, NOCO GB70 is the to-go-to device. It provides enough power for most jump-start cycles and goes a step further to ensure more devices get charged with it too. However, if you don’t require that power, the GB50 will be more than sufficient like most people. Moreover, GB70 gets recommended for applications that involve heavy-duty vehicles with large engine capacities and large-scale applications such as mechanics’ garages for jump-starting a lot of cars. That is because it is bulky and heavy, making it less ideal for every-day use.
The 1500Amps of peak current, engine capacity used, compact size, and upgraded design makes GB50 the ideal jump starter for most vehicle owners. It provides enough amperage for typical occasions, comes at a relatively reasonable price, and is the right size to fit in the glove compartment. GB50 delivers more power to jump-start a massive catalog of car batteries and a bigger battery capacity to jump-start more vehicle batteries.
For those who do not require significant amperage or have engine capacities less than 6 liters for gas and 3 for diesel, the NOCO GB40 will suffice. It is the most compact providing greater portability with still enough power for functionality. It is also the cheapest.
Choosing the best jump starter out of these models will also entail two other factors; your vehicle’s battery voltage and the engine capacity it uses.
The majority of vehicles run on 12V batteries; few run on 6V batteries, while medium and more enormous trucks can run on 24V batteries. Make sure to check your battery’s voltage and size before choosing the befitting jump starter. GB50 is more than sufficient for 6V and 12V batteries, whereas the GB70 is most suitable for the 24V batteries.
6-liter gas engines or lower will be able to use the GB40; a bigger capacity than that will require the GB50 rated for 7-liter gas engines. The same thing applies to 3-liter diesel engines or lowers, which will use the GB40, more capacity than that will require the GB50 rated for 4.5-liter diesel engines.
The GB70 will come in handy for 7-liter gas engines, 4.5-liter diesel engines, and any engine that surpasses these figures.
