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.

Our test of the Carsun electric air compressor and a comparison with Xiaomi compressors

The Carsu electric compressor arrived in stock at our e-shop Maldo.sk. We didn’t hesitate—we tested it right away and compared it with Xiaomi compressors. The Carsun compressor comes in simple packaging and includes everything you need for full, proper inflation.

All accessories except the charging cable have their own place directly in the compressor’s design. The hose is on the right side edge; at the back, under the rubber cover, you’ll find an adapter for inflating a ball, inflatables, and even a reducer for Presta (thin) valves.

From the construction side it is quite similar to Xiaomi compressors – at the front there is a large display with the option to set blowing modes for car, motorcycle, ball and bicycle. You can also switch between pressure units – PSI / bar. The display also shows the battery status – a green icon means the compressor is charged, a red icon indicates the battery is running low.

A standout feature is the air release button on the right edge. It’s a very practical feature in case you overdo the pressure a little. You don’t need to disconnect the hose and manually deflate with your finger — just press this button and the air is released from the wheel.

On the top edge, you’ll also find a USB C port for charging the compressor, a light LED panel that really shines brightly, and a threaded connection for the hose. This compressor can even be used as a power bank because it has a standard USB port for connecting a cable.

The compressor’s maximum output pressure is listed in the manual as 150 PSI, which matches all Xiaomi air pump models. We compared the inflation speed against Xiaomi compressors, and you can see the results below.

Tire inflation test of a 10″ e-scooter tire from 0 to 3.1 bar:

• Xiaomi Mi Portable Air Pump: 47 seconds
• Xiaomi Mi Portable Air Pump 1S: 27 seconds
• Carsun electric compressor: 24 seconds
• Xiaomi Mi Portable Air Pump 2: 22 seconds

As you can see, Carsun with a clear lead beats both the first and the improved generation of Xiaomi compressors, and it inflated the 10-inch scooter wheel only 2 seconds slower than the more expensive Xiaomi Mi Portable Air Pump 2.

Given the price, it’s a functionally excellent battery-powered electric air compressor that meets the needs of most users. It’s especially useful for owners of electric scooters and bicycles, but it can also inflate car tires.

The compact compressor body houses a large digital display with a control panel that shows measured values and all the information you need. The compressor reaches a pressure level of up to 94 PSI, with a maximum airflow of up to 20 liters per minute.

There are four inflation modes available for inflating balls, bicycle tires, motorcycles, and cars. You also get a built-in LED light diode, a pair of built-in 2000 mAh batteries, a power bank function, and automatic shutoff once the preset value is reached.
