What are the common types of charging cables?

A>Common types include USB Type-C to USB-A/USB Type-C, Apple Lightning to USB-A/USB Type-C, and Micro USB to USB-A.

What are the consequences of using low-quality or mislabeled charging cables?

A>In terms of safety risks, the conductors inside a charging cable, due to poor workmanship or quality, are prone to overheating or short circuits, posing a fire hazard. If the insulation layer is damaged, aged, or mislabeled, it can easily lead to electric shock, electric leakage, or combustion. Non-compliant charging cables can also generate strong electromagnetic interference, affecting the signal quality of the phone.

Regarding performance, it can result in slow and unstable charging speeds, and may even cause intermittent connections that are invisible to the naked eye, affecting the lifespan of the device’s internal components and damaging the battery. If such a charging cable with data transfer capabilities, it can lead to slow and unstable data transfer speeds, or even transmission errors. It may cause oxidation and damage to the charging port on the phone’s circuit board, especially with long-term use of low-quality charging cables. The rough workmanship of the plug interface can damage or cause poor contact with the charging port on the phone’s circuit board, leading to interrupted charging and affecting charging efficiency. There have been numerous cases of fatalities caused by using cheap charging accessories, including incidents involving low-quality charging cables.

How can we ensure the safety of our devices while charging?

A>Apart from having high-quality chargers or powerbanks, you also need high-quality charging cables. Both are equally important. While there are indeed potential risks associated with cheap charging products, there’s no need to panic excessively. As long as we maintain a high level of safety awareness, choose products from reliable manufacturers or sellers, follow the correct usage instructions, and pay attention to safety guidelines, we can minimize risks.

Why does the dvalo USB-A to USB Type-C cable have an additional 56k Ohm resistor built-in ?

A>First and foremost, our primary design consideration is to ensure that our charging cable is compatible with a wider range of USB-A devices, and to make charging more secure on USB-A ports. For instance, it allows devices like smartphones/tablets to be safely charged from the low-voltage USB-A ports of PCs and laptops. Particularly for the Nintendo Switch and other expensive gaming devices, dvalo’s charging cable effectively reduces the risk of safety hazards caused by excessive current. Additionally, it prevents the Nintendo Switch from experiencing frame rate drops (slow and abnormal display) or crashes due to unstable voltage.  In terms of overall design, unlike similar low-quality or generic charging cables, our product not only offers high quality and protects your devices while charging, but also boasts excellent compatibility. Moreover, it can extend the lifespan of the Nintendo Switch console and its battery.

Are all USB Type-C cables the same?

A>While USB Type-C is a universal connector, cables vary in internal structure, materials, and data transfer speeds. Lower-quality cables may not support all features and can compromise performance and safety.

What sets dvalo’s USB Type-C charging cables apart from other similar products on the market? 

A> All of dvalo’s USB Type-C charging cables are USB-iF certified, ensuring they meet the USB Implementers Forum’s standards for quality, performance, safety, and compatibility. Additionally, our products feature a robust plug rugged design, making them exceptionally durable.

How does a dvalo Lightning cable with an Apple MFi certified chip differ from cheaper alternatives?

A>dvalo Lightning cable uses genuine Apple Lightning IC chip.  With Apple MFi certification, users can enjoy the same charging speed and functionality as Apple’s original charging cables. Besides offering excellent stability and compatibility, it also guarantees the safety of your devices. On the other hand, those inexpensive Lightning cables, often claiming to be authentic or the same function, use cheap materials and third-party non-Apple IC. Not only do they lack the aforementioned features, but they may also fail to correctly identify Apple devices, leading to risks such as overcharging or over-discharging. Additionally, they may not be fully compatible with other iOS devices and may even pop up error messages intermittently. Only dvalo’s Lightning charging and data cables, equipped with genuine Apple Lightning IC, offer a worry-free experience.

What is USB-iF certification?

A>USB-iF is a non-profit organization that sets standards for USB devices. A USB-iF certified USB Type-C charging cable ensures compatibility, quality, and safety, allowing you to use it with confidence across different devices.

What is an E-marker chip?

A>According to USB-iF regulations, charging cables with a current exceeding 3A must embed an E-marker chip in the Type-C connector to achieve optimal charging efficiency and safety. Failure to do so may result in damage to the charging device. High-quality USB Type-C 5A charging cables that support USB Power Delivery (PD) fast charging typically include an E-marker chip. However, to cut costs, manufacturers of some low-cost 5A charging cables may omit this component. Furthermore, certain Chinese smartphone manufacturers have their own proprietary charging standards and protocols, which may have different requirements for charging cables, and some may not necessitate the use of an E-marker chip.

What is UL ?

A>UL (Underwriters Laboratories) is a globally recognized third-party safety science company that primarily engages in safety testing and certification. UL certification is one of the most authoritative safety certifications in the United States and worldwide, representing that a product has met its stringent standards in safety, performance, and quality.
