GOOLOO GT4000S Jump Starter 4000A 100W 2-Way Fast Charging, 12V Portable Car Battery Booster Pack,IP65 Power Bank Charger Box with Jumper Cables for all gasoline or 10L diesel engines

Product Information

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 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

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. Switch off the combustion system and energy-consuming features of the car like radio, headlights, etc. 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 Storage 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. On the other side, Gooloo GT4000 shows design modifications like LCD monitor, and 100W charging port, making it more user-friendly than its competitor.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

Both devices are useful for powering up 12V batteries. GP4000 supports batteries of heavier gas engines.This unit includes 8 protection features, including over-current protection, overload protection, over-voltage protection, and overcharge protection, making it extremely safe to use. 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. 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. 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.
