Los portable chargers have become one of the gadgets useful tools that accompany us most on a daily basis. Inseparable pairs of devices such as smartphonesin recent times they have decided to expand their radius of action and provide an essential service when the batteries of our tablets, drones, professional cameras or even laptops are about to run out. For this reason, we have tried four Anker brand chargers, number one in the world in mobile charging, to analyze in depth what each of them can provide us and choose the one that is most worthwhile, given its excellent value for money.
The Anker firm has transformed its catalog since the beginning of the previous decade by expanding it with external batteries, USB and USB-C chargers, including chargers with high-power GaN technology, charging cables, Bluetooth speakers and headphones, devices for home automation and home security and other smart devices. It has already sold more than 200 million products and its network of countries in which it is present does not stop increasing.
Pocket-sized: 45-watt Nano USB-C charger
One of the qualities that I liked the most about this charger lies in its design and proportions at first glance. Something that not all brands take care of equally and that they tend to disdain the more watts the charger in question provides. However, here it happens the other way around. Its 75 grams seem even less. It is also due to some very successful rounded shapes. Compatible with any operating system on the market, its 45 watts are going to become a standard in the industry, in my opinion, leaving other 20, 25 or 30 watt chargers obsolete. But How do you function on a day-to-day basis?

Its small rotating screen makes the difference
I have to confess that it surprised me for the better. In addition, it barely gets hot in any of the charging stages of the devices I have paired with it. This mini charger It is a very complete product thanks to its small screen with excellent contrast on which, at any time, you can view a series of practical data: from power in real time and its oscillation, going through choosing between standard mode o insurance or choosing to review how the charge changes depending on how full or empty the battery it is linked to is. With a simple touch you can reverse what is shown on your panel.
Of course, all the information appears in English and without the possibility of changing the language. Although, once you use it a couple of times, you realize that it is a minor detail. This is because many of the messages it offers us appear with an associated drawing and color. As for other details, we must mention how intuitive it is: everything is done with a single touch button on one of its sides using short presses.
I test four next-generation Anker chargers
Anker Nano charger: connectivity and charging times outstanding
Continuing with the analysis, this fast charger applies an efficient and fast charge to the mid-high range mobiles where I have connected it. as in me Samsung S22 or in the iPhone 15 Pro Max from a section mate. I recognize that its intelligent charging is comparable to what the manufacturer proposes: despite adapting to the energy needs of each moment, its three phases are very well distinguished: fast mode (when it reaches 20%), constant (up to 80%) and level o very slow (until it rises to 100%).
I have no problem with the place where its located. puerto USB-C —in the central part of one of its sides— although I would have liked Anker to add one more to have simultaneous charging. Despite this, I am satisfied with the overall experience. It is capable of reducing the time spent charging my phone by up to 20% or even goes further if we talk about its performance with my mid-range headphones. I want to mention that its safe mode reduces the temperature of the connected device by more than 10 degrees.
Anker USB-C fast chargers: 100 and 140 watts
If we focus on the other chargers in this test bench, I have decided to talk together about their performance. Both are quite similar in size, shape and even details, such as the elongated touch screen they include or their folding plug; This last improvement is great for storing them more easily when taking them on a trip or transporting them in a backpack or bag. At this point, In what two aspects do they differ the most?
One of them is recognized at a glance: we refer to the amount of available ports load. The 100 watt model, in my opinion, falls somewhat short in this section with respect to its older brother It has two USB-C connections and one more type A. The 140 watt one is committed to including up to three USB-C ports, something that seems like a complete success to me. Especially when it provides energy to several devices at the same time: shows higher overall performance and lower probability of internal heating.
What I am clear about is that both chargers are ideal for renewing certain basics, such as the old charger of any laptop. They complete their charge well by adjusting the power to each computer model, although the 140 watt charger improved its performance compared to its younger brother from start to finish, with less oscillation when using it, which reduced the time spent. In their box, both have a flexible and resistant cable Long enough for daily use.
Anker Zolo, 25,000 mAh: the queen of portable external batteries
Although I have several power banks distributed between my house and my work backpack, I had never had a model of ultra-fast external battery as well conceived as that of the Anker brand: both in design and weight as well as in its cutting-edge technology. It is capable of delivering up to 165 watts in total and its three USB-C ports provide 100 watts each. This gadget also has a USB-A output port. But the best is in its details (which are many).
I reaffirm this when I see its construction: given its vertical structure, it is easier to manipulate with one hand than other models in its category. Furthermore, it integrates a single button operation on one of its sides with which to interact on its screen: high contrast, it can be turned off completely, although the power bank continue working, or always show certain technical data: from the real power to its temperature.
As anecdotes to highlight, when I have connected two mobile phones at the same time, your battery, 25.000 mAh and suitable for taking into the cabin of any airline’s plane, it has been discharged at a rate of 10% every 20 minutes. Another point that caught my attention is that it also shows the health of your battery and the number of cycles it adds from the first time it is used. Last, but not least, highlight that it has a 70cm long retractable cable, and another of 30 cm, which works as Reliable and durable carrying strap.
