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 Jstar 8 has 3000 A and can jump-start up to an 8-liter

The UTRAI Jstar 8 power bank comes in a matte black colorway with a slightly textured surface for a better grip. The product dimensions are 255 x 93 x 37 millimeters. The weight is 815 grams, so you’ll definitely feel it when carrying it around.

The capacity of this battery is 74 Wh and its maximum power output for a limited time is 3000 A (12 V). With the original accessories (note from the editor: the jump-start clamps are included in the package), you get a vehicle jump-start capability for engines up to 8 liters (diesel engine) or up to 10 liters (gasoline engine).

A pair of LED diodes and a USB Type-C connector

There’s also a pair of built-in LED diodes for working in the evening or at night, as well as a physical button for starting charging. You can view the current charging info on a simple LCD display. The charging clamps have a separate connector, but you can also use USB Type-C and a pair of USB-A ports. This is the port performance under load:

• USB-C: max. 18 W (12 V / 1.5 A, 9 V / 2 A, 5 V / 2 A)
• USB-A: max. 18 W (12 V / 1.5 A, 9 V / 2 A, 5 V / 2 A)

The product bundle includes the power bank itself named UTRAI Jstar 8, as well as a charging USB-C cable, a cable with clamps for jump-starting the vehicle, a practical carrying pouch, and the necessary documentation for safe use, as tradition goes, in English.
