Fast charging technology supported by the device.
By itself, fast charging, as the name suggests, reduces the charging time compared to the standard procedure. For this, increased voltage and/or current power is used, as well as a special smart process control. But the possibilities and features of such charging may be different, depending on the specific technology used in the device. The same technology must be supported by the charger too — this is the only way to 100% guarantee correct operation. However some types of fast charging are mutually compatible — this point should be clarified separately, and compatibility is not always full.
Nowadays, the following technologies are most widely used: Quick Charge of different versions (
3.0,
4.0, 5.0),
Power Delivery (
version 3.0 and
3.1),
Pump Express,
Samsung Adaptive Fast Charging,
Huawei Fast Charge Protocol,
Huawei SuperCharge Protocol,
OPPO VOOC,
OnePlus Dash Charge. Here is a brief description of each of them:
— Quick Charge (1.0, 2.0, 3.0, 4.0, 5.0). Technology created by Q
...ualcomm and used in gadgets with Qualcomm CPUs. The later the version, the more perfect the technology: for example, Quick Charge 2.0 has 3 fixed voltage options, and version 3.0 has a smooth adjustment in the range from 3.6 to 20 V. Most often, gadgets with a newer version of Quick Charge are compatible with more old charging devices, but for full use, an exact match in versions is desirable.
Also note that certain versions of Quick Charge have become the basis for some other technologies. However, the mutual compatibility of chargers and gadgets with support for these technologies needs to be clarified separately.
— Pump Express. Own development of MediaTek, used in portable devices with CPUs of this brand. Also available in several versions, with improvements and additions as it develops.
— Power delivery. Native fast charging technology for the USB-C connector. Used by many brands, found mainly in chargers and gadgets equipped with this type of connector. Presented in several versions.
— Samsung Adaptive Fast Charging. Samsung's proprietary fast charging technology. It has been used without any changes since 2015, so it looks rather modest compared to newer standards. Nevertheless, it is able to provide good speed, especially in the first 50% of the charge.
— Huawei FastCharge Protocol. One of Huawei's proprietary technologies. Formally similar to Quick Charge 2.0, but used with both Qualcomm and other brands of mobile CPUs, so compatibility is not guaranteed. In general, it is considered obsolete, gradually being replaced by more advanced standards like the SuperCharge Protocol.
— Huawei SuperCharge Protocol. Another proprietary technology from Huawei introduced in 2016; for 2021 is available in several versions. In some devices, the power of such charging exceeds 60 V — not a record, but a very solid indicator.
— Oppo VOOC. OPPO technology, used both in branded smartphones and in products from other brands. Available in several versions; The latest (for 2021) version of SuperVOOC is for 2-cell batteries and is sometimes listed as a separate technology called Oppo SuperVOOC Flash Charge.
— OnePlus Dash Charge. A relatively old proprietary standard from OnePlus. An interesting feature is that in some gadgets, the effectiveness of Dash Charge is practically independent of the use of the screen: when the display is on, the battery charges at almost the same rate as when it is off. Technically a licensed version of OPPO's VOOC, however, these technologies are not compatible. Since 2018, Dash Charge has been phased out by Warp Charge, but this newer technology is rarely used in separately sold chargers.
In addition, on the market you can find chargers that support rarer and more specific formats of work; the features of these formats can be clarified by special sources. The presence
of a cable in the delivery kit of the charger, or any other specific type of included cable.
The presence of a cable is indicated mainly for wireless devices (see “Type”) — in such cases, we are talking about the power cable of the charger itself. For wired models, the type of connectors on the stock wire (s) for charging gadgets is usually specified. At the same time, the USB port is used by default to connect to the charger itself, so this plug may not be mentioned in the description of the wire. On the other hand, there may be such connectors:
—
USB-C. A miniature version of the USB connector, gradually replacing microUSB in modern portable devices. It has a convenient reversible plug design, and can also provide some advanced power options not available with microUSB. Also note that USB-C can be used in a cable not only to connect to a gadget, but also to connect to the charger itself (along with traditional USB); so on the market you can find corresponding cables like "USB-C — microUSB", "USB-C — Lightning", etc.
—
microUSB. Universal connector, extremely popular in portable gadgets of various types; only relatively recently has it begun to give way to the more advanced USB-C (which differs from it in its one-sided design and lower power supply).
—
Lightning. Universal conne
...ctor, used exclusively in portable Apple devices. Like USB-C, it has a two-way layout, but a slightly different design.
