Back on the EU warehouse for a brutal €46! The Utrai JS-9 jump starter power bank has up to 1500 A and a compressor in one—it can start a 6-liter engine

A powerful power bank that lets you start your vehicle or inflate a tire via the compressor. This is exactly what the practical UTRAI JS-9 model offers.

Back in stock, great price

The UTRAI JS-9 power bank is available on the well-known online marketplace Aliexpress.com. Currently, it’s only available from a Chinese warehouse, where delivery will take a bit longer—about 5 – 10 days from the Polish warehouse—and of course it will be without any additional fees.

Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

UTRAI JS-9: Jump starter power bank with compressor and 55.5 Wh capacity

UTRAI builds this power bank with a thick, heavy-duty design. It has a non-slip surface finish for a better grip, an LCD display to show current information, and physical buttons to control the device itself.

Due to the number of features, this power bank is also heavier. It weighs in at 1.3 kilograms. However, it makes up for it with a fairly high capacity for charging your devices — up to 55.5 Wh.

It can start up to a 6-liter gasoline / 4.5-liter diesel engine, and it has LED lighting

The main draw is the ability to start your car using the clamps on a special charging cable. This power bank can deliver (temporarily, for the time it takes to start your vehicle) up to 1500A. As a result, it can ultimately start a gasoline 6-liter or a 4.5-liter diesel engine.

Other features include a strong compressor with interchangeable nozzles for inflation, and a maximum output of up to 150 PSI (you can also choose to display it in bars and kPA), plus a built-in LED flashlight for working in the evening or at night on your vehicle.

Inside the retail package, you’ll find the power bank body itself UTRAI JS-9, along with plenty of original accessories from the manufacturer. This includes a jump starter cable, including a pair of clamps for connecting to the car battery, a hose for the compressor function for your tires, three different inflation adapters, a USB-C cable for charging, a hard carrying case, and a brief user manual in English.
