For Xiaomi, many external batteries are produced by Zmi. This model was no exception. It is made in a plastic case, has rounded edges and special protrusions on the front surface, which is designed to ensure a reliable grip of the device.
Xiaomi Zmi Power Bank Type-C 10000 is characterized by very compact dimensions (thickness 13 mm) and light weight (180 grams). A portable battery is available in two colour options: snow-white and black.
Power bank is equipped with a 10000 mAh lithium polymer battery and supports Qualcomm Quick Charge 2.0 fast charging technology. It works both at the input and output. The battery is fully charged for 3.5 hours. If necessary, the Quick Charge 2.0 mode can be turned off (in this case, the Power bank lowers the voltage to 5 V).
You can charge the device via microUSB or USB type C (there is no corresponding cable or adapter included). The latter port is intended exclusively for charging the Xiaomi Zmi Power Bank Type-C 10000 itself.
Xiaomi Zmi Power Bank Type-C 10000 is equipped with one USB port for connecting gadgets. The external battery automatically recognizes the device and supplies it with a current of up to 2.4 A. At 1 A (for charging most smartphones) The battery efficiency is 95%, and at 2 A the efficiency drops to 89%.
Power bank's capabilities are enough to fully charge a mobile phone with a battery up to 3500 mAh at least twice, or a tablet with a battery up to 7000 mAh once. The battery is also compatible with various low-power devices (low-current charging mode), which is important for owners of fitness trackers, smartwatches, Bluetooth headsets.
Given the low cost and the functionality offered, Xiaomi Zmi Power Bank Type-C 10000 is suitable for most buyers who need to quickly charge their mobile device.
The portable battery has become a logical development of the Asus ZenPower . Its main differences are related to the appearance of a second USB port for connecting mobile devices, as well as support for fast charging technology.
Asus ZenPower Pro is made in an aluminium case, which looks spectacular, and also provides the battery with additional strength and protection from scratches. Power bank has become 2 cm longer in length and 15 grams heavier than its predecessor. But even so, it is very compact.
The model is offered in 5 colour options: in addition to the "running" silver and black, there are versions of golden, blue or pink. Also on the end of the case near the openings there is an LED flashlight with a claimed brightness of 70 lm.
Asus ZenPower Pro is equipped with a 10050 mAh Li-Ion battery. It automatically starts charging connected devices, has built-in protection systems (against overheating, voltage surges, short circuit).
At the end, next to the only control button, there are battery level indicators. There are also two USB ports designed for a current of up to 2.4 A. For the first time, the device supports a voltage of up to 12 V (at 1.5 A), which indicates Quick Charge 2.0 fast charging. The speed of the charging process increases by 2 times when devices compatible with this technology are connected.
Taking into account the energy conversion losses, the Power bank's operating capacity is about 6400 mAh (at 5.1 V). It is enough to charge 2 modern smartphones or, for example, a tablet and a fitness tracker.
But fast charging at the entrance to the Asus ZenPower Pro does not work. When using a charger for 2 A (5.1 V), it will take at least 6 hours, and for 1 A — as much as 9 hours.
The price tag of the model is not too high, but more than, for example, Xiaomi Mi Power Bank Pro 10000. But you can count on the official service and additional "chips", such as a flashlight or a variety of colours. Taking into account these features, Asus ZenPower Pro is able to become the optimal solution.
In the fall of 2017, Xiaomi introduced a new Power bank, which is positioned as the successor to the Mi Power Bank 2 20000 model. The novelty is offered in a white plastic case, has become slightly longer and wider than its predecessor, retaining a thickness of 24 mm.
Xiaomi Mi Power Bank 2C 20000 is equipped with a 20000 mAh lithium polymer battery. Taking into account the energy conversion losses and the overall efficiency of 93%, the "net" capacity reserve available for recharging mobile devices is 13,000 mAh. This is enough to fully charge the iPad Mini twice, the flagship Xiaomi Mi 7 64GB three times, or almost 5 times the Apple iPhone X 64GB.
The external battery received two USB ports, which allows you to simultaneously energize a couple of devices. One of the ports supports Quick Charge 3.0 fast charging technology, which speeds up the charging process by 38% compared to the previous generation. To take advantage of these benefits, you need a compatible mobile device. In addition, the second port should be free during fast charging.
Quick Charge 3.0 works in two directions, so you can fully replenish the capacity of Xiaomi Mi Power Bank 2C 20000 in 6.7 hours (in modes 2 A/9 V and 1.5 A/12 V).
Other features of the portable battery include support for low-current charging (for low-power devices), the presence of a traditional display (4 LEDs) and standard multi-level protection for Xiaomi devices (against overvoltage, short circuit, overcharging, full discharge, short circuit, adverse external conditions, etc.).
The shortcomings of the Xiaomi Mi Power Bank 2C 20000 include the smallness of the case, as well as quite noticeable dimensions, which is quite natural for a Power bank of such capacity. You can recommend the model to all those who do not want to part with their mobile gadgets even while away from the benefits of civilization (for example, on long trips or hiking).
The ANKER trademark specializes in the production of chargers and external batteries. The PowerCore 10000 model is in demand not only in our country, but also in the USA, as well as in Western Europe.
The case of the portable battery is made of matte plastic. Thanks to the rounded sidewalls, the model looks miniature, and this is not a visual deception. ANKER PowerCore 10000 is one of the most compact and lightweight (180 grams) solutions, both for its capacity. The device is smaller than a deck of cards, and if you do not take into account the thickness of 22 mm, then it is comparable to a standard credit card.
The model is equipped with a 10,000 mAh battery, of which, taking into account transformations and energy losses, the "clean" working capacity is 6700 mAh. This volume will be enough for at least two charges of any smartphone, recharge from 0 to 100% of most tablets, multiple recharge of other, less powerful gadgets. However, you will have to connect the devices to the ANKER PowerCore 10000 sequentially, because the battery has only one USB output.
The chip of the external battery is the support of Quick Charge 3.0 technology, which provides additional time savings compared to QC 2.0 devices. With compatible smartphones and tablets, the charging output power will reach 24 Watts: 3 A/8 V, 2.4 A/10 V and 2 A/12 V modes are available.
The possibilities of the USB input are somewhat more modest — the current is 2 A, and the voltage is 5 V, so the rate of replenishment of the ANKER PowerCore 10000 battery capacity is lower: it takes at least 5 hours. In addition, the model, unlike most modern analogues, does not support end-to-end charging (simultaneous recharge of a mobile device and an external battery).
Even taking into account the existing shortcomings, Power bank is suitable for those who appreciate compact accessories and value every minute of their time.
Power bank presents the Ally series of the Chinese brand TP-LINK, which has created a name for itself thanks to network equipment. Like other representatives of the line, the model received a white matte case with blue inserts on the ends. In the form of TP-LINK TL-PB15600 resembles a younger "brother" at 5200 mAh — TP-LINK TL-PB5200 , but bigger and heavier than it.
Of the additional options, the external battery received an LED lamp, which can be useful, for example, in the evening in nature.
TP-LINK TL-PB15600 is equipped with a 15600 mAh LG lithium-ion battery module. He, according to the manufacturer, does not lose capacity after 500 recharge cycles, retains the claimed efficiency in the cold. The device has a multi-level protection system: against voltage surges, overcharging, short circuit, overheating, etc.
You can fully replenish the Power bank capacity in 5.8 hours (in 5V/2.4A mode), which provides support for fast charging at the input.
The external battery is equipped with a pair of USB ports with a total output of up to 3 A. The current of each outlet is automatically adjusted according to the needs of the connected device (maximum 2.4 A discharge). Smartphones, tablets, action cameras, smartwatches, portable game consoles, cameras, etc. can be charged with TP-LINK TL-PB15600.
The "pure" capacity of the Power bank, taking into account the voltage conversion, is approximately 11300 mAh. This is quite enough for 3-4 cycles of full charging of most smartphones and replenishing the battery charge of any modern tablet. The speed is also at a height (it will take less than 3 hours to replenish the phone's battery at 4100 mAh).
Confirmation of the quality and reliability of the external battery is a 2-year manufacturer's warranty (most competitors have a warranty period of a year or 6 months). This more than compensates for the minor shortcomings of the TP-LINK TL-PB15600: a short complete cable, solid dimensions of the device, a brand-name case. Given the reasonable price, we can recommend the model to all those who actively use mobile devices on trips, on outings, etc.
