Switch off the combustion system and energy-consuming features of the car like radio, headlights, etc. This unit includes 8 protection features, including over-current protection, overload protection, over-voltage protection, and overcharge protection, making it extremely safe to use.
Gooloo GP4000 presents a cleaner layout, two color schemes, and compact size. It carries a Lithium polymer battery that can discharge current up to 4000 Amperes.No. You can jump start your vehicle in three easy steps. You can simply clamp on, connect to the car battery and wait for a solid green light on the clamp, then start your car. The GOOLOO Jump Starter includes a lithium polymer battery built for operating and storage temperatures of -20°C to 60°C (-4°F to 140°F). If the ambient temperature is above 60°C (140°F), the internal cell construction of the lithium polymer battery may be damaged, causing it to swell and become unsafe. Do not store the device in a vehicle parked in hot weather for long periods of time. Conversely, GT4000 shows compatibility with low-capacity gas engines. Though it supports diesel-powered or hybrid engines with the same 10 Liters capacity yet it can only start gas engines that have a capacity of up to 12 Liters. Engine
When it comes to compatibility with vehicle batteries, GP4000 takes the lead as it supported high capacity engines than its competitor. It can jump-start diesel engines with a capacity of up to 10 liters and all gas engines. Both the Gooloo GT4000 and the Gooloo GP4000 are powerful jumpstarters, that are multi-functional and offer great alternative to traditional car battery jump starters that you can not carry everywhere. Both of these Gooloo starters are equipped with high-power cells that jump-start lifeless batteries and supply power to DC appliances as well. QC 3.0 ports enable faster charging of devices and 15V DC outputs provide effective charging through cigarette adaptor. Both of these jumpers automatically stop working if they detect an error untill the connections are made properly. Eight safety features are employed in Gooloo GP4000 to ensure safe jump-starts and prevent accidents. These features provide safety against; Looking for a jump? We researched 50 of the best jump starters available today before purchasing 9 to test side-by-side. We took an in-depth look at the performance of each option, utilizing load testers, multimeters, and clamp meters. Using these tools, we were able to assess power performance, functionality, and battery storage. We spent hours in our at-home lab looking at voltage and amperage in real time while charging different batteries and engines. After collecting the data, we compare each product to give you an in-depth overview, finding unique uses and caveats for the models that stand out; all to help you in your buying decisions.These jumpers can be recharged via a type-C port using a wall charger and via a DC port using a car charger. Although the capacity of both devices is the same, Gooloo GP4000 takes more time to replenish its power level due to the less competent charging port. It needs 7 hours to recharge to its full potential.
Both tools can jump 12 V engine batteries and can be used to power up electric appliances that utilize 12V units. However, any other battery voltage (6V, 24V, etc) is not supported by these boosters. However, Gooloo GT4000 provides more charges for mobile devices. Device
Don't let the compact size of the GOOLOO 1200A Peak fool you. This unit is a small but mighty contender in the lineup — it delivers 1,200 peak amps while weighing in at just over one pound. It also happens to be one of the most affordable jump starters we tested. Beyond jump-starting, it also features two USB charging ports, a DC power outlet with a lighter adapter, and a small LED flashlight with several modes. The USB charge ports are 5V, and a Smart charging port will bump to 9V for rapid charging on compatible devices. The 66.6Wh lithium-ion battery can provide numerous boosts to a deep-cycle SLA or up to three iPhone charges before becoming fully depleted. In our testing, this unit was capable of jumping a 6.5-liter diesel engine, exceeding the manufacturer's suggested limit. The indicator on the jumper cable will show a steady green light when the battery clamps are correctly connected to the vehicle battery. If a steady red light comes on and the unit is beeping, the connection needs to be reversed. Both devices are useful for powering up 12V batteries. GP4000 supports batteries of heavier gas engines. With a massive 26800 mAh electric capacity, it ranks as a reliable power bank for mobile devices. Its powerful current influx makes it useful for jumping batteries of high-capacity engines. Moreover, it gives low-battery, low-current, low-temperature, ready-to-start, and reverse polarity indications. The boost option is another advantage it has, allowing it to supply a huge amount of charge to an extremely low voltage battery. However, it does not come with a hard EVA storage case instead a sac-style storage pouch is included that does not provide much safety to the equipment. Design Features
This unit is perfect to jump start a dead car in ice and snow when the battery is undercharging, the car stalls while driving, or in emergencies, for medical rescue, or on road trips. By contrast, the Dewalt DXAEJ14, Clore Automotive JNC660, and Stanley J5C09 deliver a constant current when hooked up to your battery terminals. The jump starters can deliver three boosts at a full charge, although the manufacturers recommend charging after each use. This is because these models utilize SLA batteries, which discharge more rapidly than lithium-ion batteries. However, this does not mean they deliver an inferior boost; in fact, we found them fully capable of reviving even larger diesel and deep-cycle marine batteries. Among the SLA types, we were less fond of the Stanley J5C09 as it delivered slightly less current under load in our tests. Battery StorageAn AI software regulates the functioning of this booster and ensures automatic responses against various kinds of error. x 15W in/out Type C port (9V/ 2A, 5V/ 2.4A, 12V/1.5A) 1 x 5V, 2.1A USB output 1 x USB QC 3.0 output On the other side, Gooloo GT4000 shows design modifications like LCD monitor, and 100W charging port, making it more user-friendly than its competitor. The jumper cable features a smart Over-Start Protection function. If you start the vehicle more than 4 times in 2 minutes, the jumper cable will turn on Over-Start Protection: The green and red light will start to blink and the battery clamps will have no output. When you disconnect the jumper cable plug from the jumper starter, the smart Over-Start Protection will reset.
