Choosing a power bank is a rather delicate choice. Smartphones and tablets are increasingly technologically advanced devices, but from batteries, they put the user in front of frequent recharging cycles.
Even if the trend is improving, it must be said that only some smartphones can guarantee an acceptable battery life and, despite this, there is always the risk of finding yourself with the phone discharged just in time of need. Always carrying an energy reserve with you has therefore now become a concrete need for most users.

Choosing a power bank that suits our needs is important
Those who have particular battery life problems can try to optimize consumption by using the software on their model. Various apps and settings can allow you to make more or less consistent cuts in consumption, as well as the energy-saving mode.
The uninstallation of exorbitant applications in terms of energy and replacement with other more “light” programs can be the first step, the illumination reduction is then another solution rather common.
Despite this, in most cases, those who cannot recharge their smartphone or tablet once a day, will still often have to deal with exhausted batteries. The power bank, therefore, turns out to be a powerful ally, capable of making our batteries much longer.
In this guide, we explain which are the best products on the market and recommend which product to buy based on your needs.
The best power banks on the market
When we talk about power banks, we refer to a rather large market niche. There are numerous brands, even quite established ones, which offer very interesting models with excellent quality-price ratios. In this sense, they range from rather basic products, up to those that allow you to recharge up to 5 devices at the same time. Some particular models also integrate cutting-edge technologies such as Quick Charge, AiPower, and wireless charging.
Quick Charge and AiPower are two technologies that serve two similar purposes but are developed by different manufacturers, Quick Charge was made by Qualcomm
AiPower, on the other hand, is developed by Aukey and serves, in simple terms, to automatically make the external battery understand how much power to deliver to the related connected terminal. Then, there are further features which, especially in the more advanced models, present extremely interesting solutions from various points of view.
If you intend to buy a power bank, surely its capacity is one of the most important parameters to take into consideration. If we intend to use a power bank several times before recharging it, or if we use a tablet with a rather large battery, we should use a family-size model.
If, on the other hand, we want a product that is easy to carry, perhaps in your pocket or bag, we should focus on models with less autonomy but smaller dimensions. In this category, we include more or fewer devices, some of which reach 30,000 mAh.
NB: It should be considered that this type of product generally has a capacity of about 80% of the nominal one. So a 10,000mAh power bank comes in at around .8000mAh.
Anker Powerbank Wireless PowerCore
Our first proposal is the Anker Wireless PowerCore power bank. In our opinion, this is the best portable charger model currently out there. Anker is one of the best smartphone accessories manufacturers on the market and with this power bank it has managed to innovate a product category that has seen very few innovations in recent years.
Anker Wireless PowerCore is one of the first power bank equipped with wireless charging compatible with the Qi standard to arrive in Italy. Thanks to wireless charging it is, therefore, easier to charge your smartphone and you can simply take the power bank with you, leaving the cables at home.
The very useful wireless charging is flanked by excellent technical and construction features. The case is built-in opaque plastic materials able to withstand drops from 2 meters, on the body, there are 2 USB ports compatible with fast charging and a USB-C port for charging, in addition to the classic status LEDs.
A 10,000 mAh battery is added to all the excellent specifications more than enough for 2 or 3 full recharges of a top-of-the-range smartphone.
Charmast Power Bank 26800mAh
Charmast is a company that mainly deals with headphones and power banks. Its top model, or Charmast Power Bank 26800mAh, is one of the best-selling and most popular products in the entire industry.
It is a strong power bank of lithium batteries, with a capacity of 26800 mAh. This value makes the device suitable for treating almost any type of smartphone, iPhone, or iPad.
The supplied bi-directional USB Type-C port supports both fast entry and fast exit. Thanks to the Multi-Input & iSmart Output brings you to enjoy the wide compatibility of this device since it supports 3 USB ports for high-speed charging, Micro USB / Lightning / Type-c, and 4 USB Smart identification ports at the output. The Smart & Safety system allows you to monitor the battery level through its 4 indicators (25% for each indicator).
The A + Lithium-Polymer battery allows for over 500 charging cycles and has a form of protection against possible overvoltages, overloads, and unfortunate short circuits.
Also in terms of design, this product proves to be quite interesting. It is a slim power bank (only 14 mm thick ) made with solid materials but at the same time easy to carry. Charmast Power Bank 26800mAh weighs just under 400 grams.
Finally, it should be taken into account how the model can automatically detect and adjust the intensity of the current to obtain the maximum charging speed. The full charge lasts about 9 hours.
Sendowtek Solar Charger
If you intend to choose a power bank outside the canonical standards of the sector, the Sendowtek Solar Charger turns out to be an extremely interesting solution. Also, in this case, we are talking about a device capable of providing a capacity of 26800 mAh even if, as seems obvious, it is a power bank capable of being charged through solar panels.
Specifically, these are 4 highly efficient folding panels, up to 600 ma / h of input current. This makes the Sendowtek product faster than other solar chargers. The 5V 3A USB input port allows you to fully charge in about 6-8 hours. The device can count on 2 USB output ports thus allowing you to charge two devices at the same time.
As for the design, the outer shell is made of durable ABS and can best protect the battery from rain, dust, bumps, or falls. Particularly resistant and robust, the model can count on a cord through which it can be hung on a backpack. This makes this power bank perfect for hiking, camping, or other outdoor activities.
With this in mind, the model in question can be used not only as an external battery for the smartphone but also to recharge torches, camping lights, and even devices to keep mosquitoes at a distance. Built-in multiple protection safety systems can automatically protect the charging devices from overheating, short circuit, and overload.
AUKEY Mini Power Bank 5000mAh
Those who need an extremely light and compact power bank, on the other hand, can focus on AUKEY Mini Power Bank 5000mAh. The product in question, weighing just over 130 grams, is undoubtedly one of the easiest devices to carry in the entire industry. Dwelling on other technical specifications, however, it is clear that the positive characteristics of the AUKEY product are also others.
As it is easy to guess, as far as power is concerned, we are dealing with a 5000 mAh power bank. Not comparable with previous models, but still more than usable for those who want to charge only their smartphone and not other devices. The product offers a low current mode, which makes it particularly suitable for charging low current devices such as fitness trackers and wireless headphones.
AiPower technology is also available. It is capable of providing maximum charge safely to USB-powered devices. Then there are the necessary protections capable of canceling the risk of overload and overheating of the devices being recharged.
AUKEY Powerbank 20000mAh
We remain on AUKEY products, which in this sector is one of the most important companies, proposing the excellent AUKEY Powerbank 20000mAh. It is one of the most purchased power banks in digital stores and, already this information, says a lot about its quality. With its 20000mAh, it can charge an iPhone X up to 5 times or a Galaxy S20 Ultra up to 4 times.
Thanks to its total compatibility, it is possible to charge both iOS and Android devices through the same cable. The power bank in question offers 2 USB ports, 3.4A output and can therefore simultaneously charge 2 iPads at maximum speed and in complete safety.
As usual, there is a safety system capable of guaranteeing protection from overload and overheating. In addition to the actual device, the package includes the Micro-USB cable (20 cm long), an instruction manual, and a warranty valid for 24 months.
The price-quality ratio of this power bank makes it one of the most coveted models in the entire sector.
We conclude this list with a rather interesting low-cost product. This is the Vonpri 10000mah portable charger, characterized by low weight (just over 200 grams) and a compact design, which makes this power bank particularly easy to carry.
The device in question has 2 USB output ports (2.1A and 1A) through which two separate devices can be charged simultaneously. On the same model, there is an LED flashlight that can be activated by pressing a simple button. This is a very useful solution in case of emergency, hardly proposed by other similar models.
Another salient feature of Vonpri 10000mah is the very high compatibility. Be it tablets, MP3 players, eBook Readers, Apple devices, or Android smartphones, this power bank works excellently.
The technology Intelligent Power Management IC allows charging without risk. It protects the devices being charged from overvoltage, short circuit, and any other type of problem.
