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.

Accurate measurements and modern technology

One of the main advantages of this tester is its ability to measure resistance in the range of 0 – 100 Ω and voltage up to ±110 V DC with an accuracy of ±0,5 %. It uses an AC 1 kHz method combined with four-wire Kelvin measurement using Kelvin clamps, ensuring consistent results. This principle is very popular in professional devices where eliminating the influence of wire resistance is crucial.

The device has automatic ranges for both voltage and resistance, while users can also set manual modes for more precise calibration. A practical add-on is the ability to set threshold values—so the tester immediately sorts batteries according to your specified parameters. You’ll appreciate this especially when working with a larger number of cells, where you need to quickly separate the pieces with worse characteristics.

Practical use in the workshop and on the go

Fiizreal PBRM-1 is compact and lightweight (only 160 g), so you can take it with you even into the field. With dimensions of 135 × 80 × 24 mm, it’s a highly portable tool. Thanks to the built-in 1200 mAh battery with USB-C charging, it lasts long during operation and you don’t have to constantly recharge it while testing.

On the large TFT display, you can view the data clearly, and you can even adjust the display colors or set an automatic power-off. The user can save calibration values, ensuring consistent results even with long-term use.

Package contents and specifications

In the box, you’ll find the tester itself, specialized four-wire Kelvin clamps, and a user manual. So, there’s nothing missing if you want to start using it right away. With its accuracy and measurement speed, the Fiizreal PBRM-1 is a great helper for testing battery quality in both hobby and professional projects.

Fiizreal PBRM-1 is useful for anyone who works with lithium cells. Whether you’re a designer building your own power banks, a technician testing batteries for electronic devices, or an enthusiast assembling battery packs at home, this tester saves you time and delivers reliable results. With the sorting mode, you can immediately check which cells are usable and which should be discarded.

Overall, it’s a very well-made tool that offers features more commonly found in professional measuring instruments—yet at an affordable price. If you’re looking for a precise, portable, and reliable tester, Fiizreal PBRM-1 is a choice you won’t be disappointed with.
