He does some of the best real world test reviews out there. He tested 14 jump starters, including the Gooloo. The Gooloo jump starter came in second place overall and it was just $99. The first place jump starter was $370. An almost 4 times price increase for just a little improvement over the Gooloo jump starter. It arrived well packaged and included a ton of accessories. The Gooloo lets you jump start your car (which was super simple and worked great). But, it also has a built in light with several illumination patterns. I has two USB A output ports for charging your devices. A USB C port for charging the the Gooloo internal battery. The same USB C port can also be used as an output to charge your own device. It charged my video light at an amazing 40 watts (see my photo below of it charging). It also has a DC out port at 15V. There is a female cigarette lighter for the DC out port. However, I think 15 volts is a little high form some devices meant to run at 12 volts. So use caution. There is also a male cigarette lighter with a male USB C plug so you can charge the Gooloo from a standard cigarette lighter socket. There is a USB A to USB C male cord and a double male USB C cord included. This is a very complete package. I charged the Gooloo to 100% and then did a test start on my 4Runner. My 4Runner has an older battery that I am too cheap to replace. I tried to start the car, but it just went, "click, click, click." So I hooked up the Gooloo jump starter and it fired right up. Not only did it start, it cranked the starter with authority. As Project Farm would say, Very Impressive! The size of the Gooloo is larger then most jump starters. But, that is because it has a massive battery inside which provides the excellent performance. But, it is not too big to be cumbersome. Everything fit nicely into the provided storage bag. The instructions were very clear and simple to understand. Overall, I am super impressed with the Gooloo jump starter. Review: Better than jumper cables. - Holds charge for long time, months and works great although the bi-directional charge cable quit working after only a couple uses. ## Features - ONE & ONLY 100W Fast-Charging Car Battery Jump Starter: Only 1.2 hours can fully charge the jump box from 0% to 100%. 5 minutes of charging time are enough to start a car(100W car charger is included in the package). A single full charge can achieve 60 times jumpstart. You can also use your own fast-charging charger to charge this jump starter through the type-c port. - Up to100W Charging Speed for MacBook & Other Laptops: Charge it whenever and wherever as fast as the original adaptor for your laptops(Type-C port only). - Powerful yet Compact Portable Jump Starter: Powered by GOOLOO JUMPCORE technology, the GT4000S delivers 4000A of peak starting power and can jump-start nearly all 12V vehicle engines, including gasoline engines up to 12.0L and diesel engines up to 10.0L, in just a few seconds. Unlike traditional car jump starters or jumper cable kits, it offers superior power in a more compact form. It's perfectly compatible with RVs, pickup trucks, motorcycles, SUVs, tractors, boats, and more. - Easier & Safer to Jump-start: Built with GOOLOO SUPERSAFE technology, this portable lithium car battery jump starter pack has a 3.2-inch informative LED screen clearly to show product status , so you can know when to start the car intuitively. Built-in 10 kinds of protection technology to free your mind of misgivings of misoperation and sparks. - 24 Months Stand-by Time: Regular charging is not necessary as long as you own the GT4000S battery jump starter. The built-in 10 protection technologies also greatly extend the service life of the product. - More than a Battery Jump Starter: Built around GOOLOO TOOLCORE technology, the GT4000S combines multiple roadside and emergency functions in one portable unit. It features three USB ports for charging emergency devices and a 400-lumen flashlight with three modes: SOS, spotlight, and strobe. It also includes a 15V/10A DC output for powering compatible 12V or 15V DC devices, such as tire inflators and inverters. - In The Box: Gooloo 4000A Portable Car jump starter battery pack GT4000S, Heavy Duty Jumper Cables, SC 100W Car Charger, USB to Type-C Cable, Type-C to Type-C Cable, Cigarette Lighter Adapter, Storage Bag, User Manual. - For the best performance, fully charge the jump starter before first use and recharge it at least once every 3 months during long-term storage.

Delivers a lot of power in a small package! *by M***V on September 12, 2025* I found out about the Gooloo brand on YouTube (Project farm). At a price that's 1/3 of the NOCO charger he tested, this is a very powerful unit for a much more reasonable price! I'd really give it a 4.5 if I could; knocking it down .5 of a point since Gooloo doesn't include a wall charger. No worries I have a 2 amp wall charger that is more than powerful enough to get the unit to 100%. Very pleased with the first use! It started my car right up. LED display is a great feature. DC output is a nice feature if you need to power other 12 volt tools. Don't buy the $69.00 Gooloo 100 watt wall charger; there are many other 100 watt wall chargers available on Amazon for 1/3 of the price. Update: It's now 29 Nov 25, and the unit is totally dead. I've contacted support@gooloo.com; I'll report back when I hear from their warranty department. Fiona at Gooloo stepped addressed my warranty issue, and I had a new unit in 5 days. Excellent customer support; I hope this new unit lasts longer! ## Frequently Bought Together - GOOLOO GT4000S Jump Starter 4000 Amp Car Starter 100W Two-Way Fast-Charging Portable Car Battery Charger Booster Pack for 10L Diesel and 12L Gas Engines, SuperSafe Lithium Jump Box for 12V Vehicles - GOOLOO Eva Protection Case for GT3000 GT4000 GT4000S 12V Jump Starters,Portable Hard Storage Case Car Tool Gadgets Carry Ba - GOOLOO A3 Jump Starter with Air Compressor, 3000A Portable Car Battery Booster (9.0 Gas/6.5L Diesel) with 150PSI Auto-Shutoff Tire Inflator, 12V Supersafe Lithium Jump Box Car Battery Jumper Starter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/406861673-gooloo-gt4000s-12v-4000a-peak-jump-starter-with-100w-two](https://www.desertcart.gr/products/406861673-gooloo-gt4000s-12v-4000a-peak-jump-starter-with-100w-two) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-06*
