By way of its official Amazon storefront, GOOLOO is offering a return to the best rate yet on its GT4000 Car Jump Starter back at $104.49 shipped. These days, this upgraded model to the more popular GP4000 model usually fetches $160 at full price, which we’ve been seeing hold out at a Prime-exclusive $110 for much of 2025, with occasional falls lower to this rate since it first appeared during July’s Prime Day event. You’re getting another shot at it today, with $56 cut from the tag for the best price we have tracked.
One of the worst feelings as a driver after getting into what you think is a perfectly running car, is finding the battery dead and unable to go anywhere – especially if this occurs as you’re bound for important dates, meetings, and the like. GOOLOO’s GT4000 jump starter is a great way to always be prepared for such situations, especially considering just a 5-minute charge gives it enough juice to start your car, while getting it to a full battery takes 1.2 hours. What’s more, the 24,000mAh battery doubles as a power bank for your personal devices, with two USB-A ports and a 100W USB-C port, complete with a more advanced 3.2-inch LED screen for charging status and setting controls.
Of course, if you want to save a little extra money there’s also GOOLOO’s predecessor GP4000 Jump Starter currently down at its second-lowest price of $89.99 shipped. It offers much of the same performance and functionality with key differences. For one, it can only reach up to 15W charging speeds, while also sporting a more basic display screen that doesn’t provide as thorough information as its upgraded counterpart above.
Speaking of your car, if you’re planning to head out for any fall camping or road tripping, you’d do well to prep with a portable backup power solution and right now we have several ongoing sales from our favorite brands like EcoFlow, Anker SOLIX, Bluetti, and Jackery – all collected within our Green Deals hub, with those from last week rounded up into our most recent Electrified Weekly edition here.
