Magic 30 cards are a popular type of card deck used in magic tricks and illusions. These card decks consist of only 30 cards, unlike traditional decks which have 52 cards. The purpose of using a deck with fewer cards is to make certain magical effects easier to perform and execute. One of the main advantages of using magic 30 cards is that they allow magicians to perform tricks that require a specific set of cards without having to carry around a full-sized deck. This makes it more convenient for magicians to perform on the go or in situations where a full-size deck would be impractical. Additionally, the smaller deck size also allows for faster and more efficient card manipulation.
Detailed specifications of the LD8526.
8-inch AMOLED screen has ultra-thin bezels and boasts a class-leading vivid display with 120Hz refresh rate , and 1300 nits of daytime-ready peak brightness. To give a couple more comparison points, the OnePlus 7 Pro managed 11 hours and 50 minutes, while the Google Pixel 3 only made it to 7 hours and 21 minutes.
Additionally, the smaller deck size also allows for faster and more efficient card manipulation. With fewer cards to handle, magicians can move quickly and smoothly through their routines, adding to the overall impact and aesthetic of the trick. This can be particularly useful for tricks that involve sleight of hand or complex card shuffling sequences.

Skysilicon synchronous rectification driver and LD8526 MOSFET on the secondary side. Leadtrend LD8526 is a secondary side synchronous rectification (SR) driver IC designed for PD. It was suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. LD8526 can generate its own supply voltage through low output voltage or high side rectification applications to charge the battery, suited for PD application, which output voltage range from 3V to 20V. In light load condition, LD8526 will enter green mode to reduce operation current by stopping the SR MOSFET driving function.

Magic 30 cards also provide a unique challenge for audiences. Because the deck is smaller and contains fewer cards, spectators are often more intrigued and engaged with the trick. They may be more likely to focus on the deck and try to figure out how the magician is manipulating the cards, adding an extra layer of mystery and excitement to the performance. However, it's important to note that using a smaller deck does limit the range of tricks that can be performed. Some illusions or routines may require a full set of 52 cards, and will not be possible with a magic 30 card deck. Additionally, certain card games or gambling demonstrations may not be feasible with a reduced deck size. In conclusion, magic 30 cards offer a convenient and efficient option for magicians looking to perform card tricks and illusions. They allow for faster manipulation, increased engagement from audiences, and are easier to carry and handle. However, it's important to consider the limitations of a smaller deck size when planning performances and selecting tricks..
