Google Trends has winter storm spiking in the US this morning: 50K+ searches, up 1,000%, still Active. Right now the actual storm is in Alaska, where snow is hitting the Haines Highway, and forecasters are watching a system that could bring rain, snow, and wind to parts of the Northeast late this week. Either way, the season of the car that clicks instead of starting has officially opened.
The GOOLOO GT4000 Arctic is a portable jump starter built for exactly that sound. Its party trick is battery preheating: GOOLOO built it to start vehicles reliably in temperatures as low as -40°F and as high as 140°F. Most battery packs get sluggish in the cold. This one warms itself up first.
It puts out 4000A peak current for 12V vehicles up to 12L gas and 10L diesel engines, so cars, SUVs, pickups, motorcycles, and ATVs are all in range. A BOOST mode handles batteries that have drained extremely low, the kind of dead you get after a week parked in a snowbank.
Storage is the point of a gadget like this, and it holds a charge on standby for up to 24 months. GOOLOO says to top it up every six months. When you do, the included 100W car charger takes it from 0 to 100% in about 1.2 hours.
It also earns its glovebox spot on days your car starts fine. There is a 100W USB-C port that can charge a laptop, two USB-A ports, a 150W DC output, and an LED flashlight with high-beam, strobe, and SOS modes. If the power goes out at home, it is a big power bank with a flashlight attached.
The safety side comes from a built-in battery management system with 10 protections, including spark-proof and reverse-polarity protection, so you are not doing the old jumper-cable guessing game in the dark.
Who it's for
- Cold-climate drivers who park outside and have heard the click.
- Anyone building a car winter kit before the first real storm of the season.
- Gift shoppers with a new driver, a college kid, or a parent who still does not own one.
Who should skip it
- You already carry a working jump starter and keep it charged.
- You want a home backup battery. This is a car tool with power-bank extras, not a home power station.
