What our readers and customers say
With jump starter power banks, one thing decides—something you can’t read from the specs table: how well it holds charge when it’s been sitting in the trunk for months. And two of our readers answered that for us.
Reader Ján wrote to us that he has been using the Jstar 5 for a year and a half, carries it in the car trunk, and parks it outside. During the first winter from October to March, its capacity dropped on its own to just 93 % — while, according to him, his previous power bank self-discharged in two months. He mainly uses it to top up tires, and once he started a 2-liter gasoline engine with it completely without problems. His only criticism was the case: it looks nice, but it takes up quite a bit of space in the trunk.
His experience is confirmed by reader viliam, who has the power bank in his car for half a year including winter temperatures around -25 °C. According to him, the battery capacity is still fine and his Citroën C3 starts without any hesitation.
On AliExpress, UTRAI 4 in 1 Jump Starter is rated 4.9 out of 5 stars from over 900 reviews and has sold over 5,000 units. Users most often praise reliable starting even with a completely dead battery and in frost around -10 to -16 °C, with successful starts of smaller diesels and even big engines mentioned in reviews, including 4.4- or 5.7-liter V8s. The built-in compressor is also highly rated—one user managed to inflate a 195/65 R15 tire from zero to 2.2 bar in under five minutes.
Let’s be fair even about what gets repeated in the criticism. Customers are bothered by the weaker LED light and the shorter starting cables, which can make it tricky to connect to the battery on some cars. Otherwise, the reviews are unusually consistent, and customers praise UTRAI especially for an excellent price-to-performance ratio and reliability in real-world conditions.
Universal 4-in-1 device
This great power bank is a multifunctional device because, besides the ability to charge and jump-start your car, it also has an electric air compressor and LED light. A power bank that does even more functions is definitely going to appeal to plenty of drivers.
The power bank itself measures 20 x 153.5 x 77 mm and offers an excellent capacity of up to 24,000 mAh. It charges via the USB-C port, and you can use 2 USB ports to charge other devices. One of them supports QC 3.0.
Car starting
UTRAI Jstar 5 can not only start a car, but also a motorcycle, ATV, and even a truck or a boat. You can start gasoline engines with a maximum displacement of 8 L or diesel engines up to 6.5 L.
The maximum current the power bank can provide for starting is up to 2000 A. Thanks to the high battery capacity, you can start your car on average 25 times per charge.
UTRAI Jstar 5 can operate in temperatures ranging from -20 to 75 °C. It’s made from quality ABS material and promises high durability and a long service life.
Compressor, display, and other features
As we already mentioned in the introduction, UTRAI Jstar 5 also serves as a compressor. With this power bank, you can easily inflate anything you need.
The power bank has 2 LCD displays. One is for the compressor and the other shows the remaining capacity.
In addition to the power bank itself, the package also includes a carrying case, car jump starter clamps, a cigarette lighter cable adapter, a USB-C cable, 3 compressor adapters, and a user manual.

exactly like in the first comment, I have it in my car for half a year in winter at minus 25 and the capacity of that battery is still OK.
I use it to jump-start a Citroen C3 without any problems . . .
unfortunately the coupon code doesn't work, message:
Sorry, the coupon code you entered is based on a first come first served basis and has been used up by other shoppers. Please enter a different coupon code or explore other discounts on AliExpress.
It can now only be used with the 3 euro one – 29WS03
Thanks, after using this new coupon, it gave me an 8 euro discount;)
I've been using this for 1.5 years now, carrying it in the car trunk, parking outside. After the first winter, from October to March, the capacity dropped on its own by only 93%. What I had before discharged itself in 2 months.
It is expensive, but the battery quality is above standard. I mostly use it for topping up tires, once also for jump-starting, admittedly with “only” a gas two-liter engine, but it started completely without problems.
The case is nice and handy, but a bit too big, it takes up quite a lot of space; otherwise 100% satisfied.
