Battery type
The type of own batteries installed in the power bank. Lithium-ion(Li-Ion) or lithium-polymer(Li-Pol) batteries are most commonly used today. Other options are less common — solutions based on nickel-metal hydride(Ni-Mh) batteries, as well as on LiFePO4 type cells. In addition, a rather promising development has appeared relatively recently — graphene batteries; however, as of early 2021, they are just beginning to be introduced into mass production. Here are the main features of each of these varieties:
— Li-Ion. Lithium-ion technology allows you to create quite capacious batteries of small dimensions and weight. In addition, such elements are easy to use (the main operating parameters are regulated by the built-in controller), have a high charge speed and are practically not affected by the "memory effect" (reduction in capacity when charging an incompletely discharged battery). The main disadvantage of lithium-ion batteries is a rather narrow range of permissible ambient temperatures. This is not a problem in urban usage, when the power bank is used mainly indoors and is carried in a pocket or in a bag; but for less favorable conditions (such as long hikes in the cold season), it is worth choosing models with good thermal insulation. You can also find information that lithium-ion batteries are prone to fires and even explosions; however, this is usually due to...failures in the embedded controllers, and these controllers are also constantly being improved, and nowadays the risk of such an accident is so low that it can actually be neglected.
— Li-pol. Further development and improvement of the lithium-ion technology described above; the main difference is the use of a solid polymer electrolyte instead of a liquid one (hence the name). This made it possible to achieve even greater capacity without increasing the dimensions, as well as to reduce the potential for fires and explosions during abnormal operation. On the other hand, lithium-polymer batteries are somewhat more expensive than lithium-ion batteries and are even more sensitive to temperature disturbances.
— Ni-Mh. Nickel-metal hydride batteries are distinguished by their reliability and a wide range of permissible temperatures, however, with the same dimensions, they are inferior in capacity to lithium-ion (and even more to lithium-polymer) batteries, and they also require certain specific operating rules to be observed. In addition, it is worth noting that Ni-Mh technology is well suited for removable batteries. It is in this format that such batteries are most often used: power banks of the Ni-Mh format are usually adapters with slots for several replaceable elements of a standard size (for example, AA). In this case, usually, several corresponding removable batteries are included in the kit, however, if desired, they can be replaced with other elements — these can even be disposable batteries from the nearest store. Such an opportunity can turn out to be very useful if the power bank is out of juice at an unfortunate moment, but there is no way to charge it; in addition, worn-out batteries can be replaced with fresh ones without changing the entire device.
— Li-FePO4. Another modified version of the Li-Ion batteries described above, the so-called "lithium iron phosphate". The advantages of such cells over classical lithium-ion ones are, first of all, a stable discharge voltage (until the energy is exhausted), high peak power, long service life, resistance to low temperatures, stability and safety. In addition, due to the use of iron instead of cobalt, such batteries are also safer to manufacture and easier to dispose of. At the same time, they are noticeably inferior to the classic lithium-ion ones in terms of capacity, and they are more expensive, which is why they are rarely used.
— Graphene. Batteries based on graphene — a carbon film one atom thick. The battery itself consists of a set of such films, between which silicon plates are laid, and lithium cobaltate or magnesium oxide is used as an anode. This design provides a number of advantages over the earlier batteries described above. First, graphene technology provides a high charge density, which allows you to create capacious and at the same time light and compact batteries. Secondly, for the production of such batteries, fewer rare resources are needed than for the same lithium ones; and the production itself is more environmentally friendly. Thirdly, such batteries are not prone to overheating and explosions when overloaded or damaged. On the other hand, graphene power supplies take a long time to charge and are not durable. However, this technology is still developing, and in the future it is likely that these shortcomings will be eliminated — completely or at least partially.

USB-C
The number of modern ports USB-C and built-in USB-C cables that can be used to charge smartphones, tablets, headphones, consoles, and other current devices. This format is particularly convenient today because USB-C has become the main connector for most new devices and usually supports higher charging power than USB-A. One USB-C output is usually enough for everyday use, while two and three are convenient if you need to connect several gadgets at the same time.
USB-C1
The power capacity of the main USB-C port, which among USB-C connectors is typically the most powerful. This specification is especially important for smartphones with fast charging, tablets, portable consoles, and laptops that require increased power supply.
Values around 18 – 30 W are usually sufficient for fast charging smartphones, 45 – 65 W are suitable for portable consoles, some ultrabooks, and other more demanding devices, and 100 W and above are even designed for powerful laptops and heavy loads.

USB-C2
Maximum output power of the second USB-C port, which usually lags behind USB-C1, but can still be suitable for fast charging smartphones, portable consoles, and other modern devices.
Power bank charge power
The power in watts at which the power bank is charged under normal conditions.
The higher the charging power, the less time it takes to charge (given the same battery capacity). For example, fast charging of a power bank typically means a charging power of 30W or more. However, this parameter does not directly affect compatibility with charging devices: modern portable batteries can work with chargers of both higher and lower power. In the first case, the battery controller will automatically limit the charging current, while in the second case, charging will simply take more time.

Fast charge
Fast charging technologies supported by the power bank. This is primarily about charging external gadgets, but the same technology can also be used when replenishing the power bank itself.
The fast charging feature, hence the name, can significantly reduce the time spent on the procedure. This is achieved through increased current and/or voltage, as well as smart process control (at each stage, the current and voltage correspond to the optimal parameters).
Fast charging is especially important for devices with high-capacity batteries that take a long time to charge normally. However, to fully use this feature, the power source and the gadget being charged must support the same charging technology; at the same time, different technologies are not compatible with each other, although occasionally there are exceptions. The most popular fast charging formats these days are QuickCharge (versions 3.0, 4.0 and 4.0+), Power Delivery (Power Delivery 3.0 and Power Delivery 3.1), Pump Express, Samsung Adaptive Fast Charging, Huawei Fast Charge Protocol, Huawei SuperCharge Protocol..., OPPO VOOC, OnePlus Dash Charge ; Here are the specific features of these, as well as some other options:
— Quick Charge (1.0, 2.0, 3.0, 4.0, 5.0). Technology created by Qualcomm and used in gadgets with Qualcomm CPUs. The later the version, the more advanced 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 also compatible with older devices for charging, 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, again, the mutual compatibility of chargers/power banks and gadgets supporting 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 type C connector. Used by many brands, found mainly in chargers (including power banks) and gadgets using 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, in light of which it looks quite 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 processors, 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 quite an indicator.
— Oppo VOOC. OPPO technology, used both in branded smartphones and in equipment 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 still rare in separately sold chargers and power banks.
— PowerIQ. Technology developed by the Anker brand. The key feature of PowerIQ is that it is not a standalone standard, but a combined format of operation that combines a wide range of popular fast charging formats. In particular, version 3.0 claims the ability to work with Quick Charge, Power Delivery, Apple Fast Charging, Samsung Adaptive Fast Charging and others.

Bundled cables (adapters)
Types of cables and/or adapters for charging external devices included with the power bank.
The type of these cables is indicated by the plug used to connect to the charging gadget; the connection to the power bank itself is usually through a standard USB-A or USB type C output. It should be emphasized that this refers to removable cables/adapters; types of built-in charging cables are specified separately (if available — see below).
Overall, this parameter allows you to assess the capabilities of the power bank available "out of the box," without purchasing additional accessories. As for specific interfaces, most external batteries these days come with cables/adapters for microUSB, USB type C, and/or Lightning; more specific connectors are extremely rare. Here are the features of the most popular options:
— microUSB. A connector extremely common in modern portable gadgets. It is less convenient than the newer USB type C and has fewer working characteristics, but it still maintains popularity.
— USB type C. A relatively new standard for miniature USB connectors, used for charging both in portable devices and larger ones — particularly some ultra-compact laptops. Physically, it differs from microUSB with slightly larger sizes and a reversible design, allowing the plug to be connected in either direction. In terms of performance, USB...type C is notable for better compatibility with fast-charging technologies: more such technologies can be used with it, and Power Delivery was originally designed for this connector. However, having a USB type C cable does not necessarily mean support for fast charging.
— Lightning. A standard proprietary connector used in compact Apple gadgets; such technology is not found with other manufacturers.
Note that if several types of included cables/adapters are specified in the characteristics, the specific format of such accessories may vary. For example, the "microUSB plus USB type C" option could mean two separate cables, one cable with two plugs, a cable with one connector plus an adapter for another, etc.
