In this video I unbox and fully test the GOOLOO A5, which combines two of the most important emergency items I always recommend keeping in your car: a jump starter and a tire inflator. This is their latest model, and it’s one of the beefier all-in-one units I’ve seen—rated at 4000A for jump starting and 160 PSI for inflation. I walk through everything in the kit, including the carrying case (perfect for the trunk), the jumper cables, the thick air hose with multiple nozzle attachments, and the built-in USB-C cable. Then I take it outside and do a real-world tire test. I drop my tire down and run an inflation test from 19 PSI up to 35 PSI, timing the results and watching how the auto shut-off works. I also show the screen, the different preset modes (car, motorcycle, bicycle, basketball, etc.), the PSI adjustment buttons, and the built-in flashlight with strobe for roadside safety. My takeaway: the screen is the nicest I’ve seen on one of these, the auto-stop worked exactly as it should, and the inflation speed was solid for topping off tires quickly.
