Modern smartphones from the related brands Xiaomi, Redmi, and POCO are charged primarily via the proprietary HyperCharge protocol, which is known for its high power, reaching 300W, and for using proprietary USB-A - USB-C cables capable of carrying high current, up to 10A and above. Over time, Xiaomi added support for the PD protocol to its HyperCharge chargers, most often with power up to 65W. When using the original cable, such a charger can be used to charge, for example, a

Apple Smartphones 2025-2026 (April): iPhone 16e (2025) supports PD charging at 5V, 9V up to 3A (up to 25W at 9V in real use, theoretical max. is 26W - documentation ) iP

Image source: Apple Newsroom In 2026, Apple updated its laptop lineup by introducing models based on the M5, M5 Pro, and M5 Max chips. At the same time, the lineup also gained the new MacBook Neo 2026 with a 13-inch display and the A18 Pro chip. In the US market, it comes with a bundled 20W adapter, which at first glance looks rather modest. However, in practice, the charging situation with current MacBooks is more flexible than the package contents might suggest. With MacBoo

​Short answer : Yes, it can! If it's a 2-in-1/Y-cables. Let's look at why they are so dangerous and whether exceptions exist. ​ ⚠️ Concern 1. What voltage is transmitted through the USB cable?​ ​Regular USB cables with any type of connectors (UsbC, micro USB, UsbA etc.) if it is not broken or damaged, cannot harm your device because safety is built into the USB standard, and all USB devices are either able to accept 5V or simply won't turn on because the voltage is too low fo

​ The short answer is that it could be due to a cable, a charging adapter, and/or an incompatible fast charging protocol. Let's take a closer look at each of these factors. ​ Situation : Your smartphone supports fast charging, but when connected to a charger, it charges slowly. Here are a few reasons for this unpleasant situation. ⚠️ Reason 1. The charger and/or cable is defective. Try connecting using the same cable and the charger to another smartphone that supports fast c

Short answer : No, the fast charging doesn't harm it, and let's figure out why. ​ To answer this question, there are 3 factors to consider: ⚠️ First factor: Battery chemistry and its limitations. Smartphones most commonly use Li-Ion and Li-Pol batteries, which are very similar in terms of their design and chemical processes, although Li-Pol batteries may have slightly higher voltages (up to 4.35V). These two types of batteries are often referred to by the generic term, lithiu
