Both the Gooloo GP4000 and the Gooloo GP2000 are powerful jump starters, that are multi-functional and offer great alternative to traditional car battery jump starters that you can not carry everywhere. These are heavy-duty jump starters from the Titan series by Gooloo that can boost up empty batteries of gas or diesel engines as well as tablets and mobile. Multiple USB outputs, type C in/ out port, and advanced DC port make the charging and discharging ability of these devices very efficient.
Gooloo GP4000 shows a superior performance taking the benefit from its capacious internal battery and high peak discharges. Greater current influx upon cranking make jumping action further quick and efficient. Compact design allows easy management and a bright 1-watt flashlight featuring multiple modes make it useful as camping or working light. It stores up a high charge and restores engine and mobile batteries many times over a single charge.
Gooloo GP2000 carries a 19800 mAh Lithium-Ion battery, offering quick restoration of dead batteries. Being lightweight and compact, it can be stored without any hassle in its EVA storage shell. Supersafe technology employs numerous mechanisms to prevent overloading of the battery or spark triggering due to reverse polarity, resulting in a strong resistance against short circuits. A lower price makes it more economical in comparison.
In comparison to Gooloo GP2000, GP4000 has a high volume battery, shows a higher peak current rating, supplies more charge on cranking, work for heavier engines, and provides more starts per charge. However, its price and weight are relatively higher.

Operation Comparison
Both Gooloo starters utilize an identical procedure to charge up a dead battery. These devices can be operated in the following easy and simple steps;
- Turn off the ignition system and power gadgets of the car to reduce power consumption.
- Attach clamps-cable into jumper cables socket of the device.
- Attach clamps to respective battery terminals.
- Power on the starter to boost the empty battery.
- Restart the engine and remove the starter equipment.
These devices can be used effectively in colder regions even when the temperature falls to -20° Celsius and remain functional up to 40° C. Likewise these can be recharged effectively in a wide temperature range.
| Environmental Conditions | GP4000 | GP2000 |
| Operating Temperatures | -20° to +40° C | -20° to +40° C |
| Charging Temperature | 0° to +45° C | 0° to +45° C |
Design Differences
Both devices have a similar outlook and size but Gooloo GP4000 weighs heavier than its competitor. It comes in yellow and orange variants with an EVA storage box. Ports’ panel includes in/out type C, QC output, 5V/ 2.1A output, DC output, and jumper cable socket. The power button and battery indicator are present on the upper side. It also contains a 1W LED flashlight that can be utilized in three modes (SOS, Strobe, and Stable).
Gooloo GP2000 is identical design-wise and carries the same input and output sockets and LED torch. However, it is comparatively lightweight and is available in red and yellow variants. Both devices can be easily handled due to their small size, moreover, advanced USB and DC ports allow faster charging and discharging.
| Physical Characteristics | GP4000 | GP2000 |
| Color | Black and Yellow/ Orange | Black and Yellow/ Red |
| Weight (lbs.) | 4.24 | 2.81 |
| Height (inches) | 1.49 | 1.29 |
| Width (inches) | 3.92 | 3.92 |
| Length (inches) | 8.97 | 8.97 |
Recharging
Both boosters carry charging ports and can be easily recharged through AC or DC power supply via respective adapters. As they carry high-power batteries, they also require a long time to restore their full potential, taking 7 hrs for a single charge. Although Gooloo GP4000 stores more charge yet its efficient charging interface allows fast charging and it powers up completely at the same time as its competitor.
