A power bank is a portable source of energy for your devices: you can easily charge your device several times even if there is no power plug nearby. Such portable batteries come in different capacities and are extremely handy when traveling or when you are on the road. AliExpress offers many different models, and in this article, we picked up the best power banks available on the market.

How to choose the best Power Bank

Capacity, measured in mAh, is the most important feature and the main indicator of a power bank’s performance. The larger the number, the more power you’ll have to charge your devices. But note that the power banks with big capacity tend to be bigger and bulkier, so if you are looking for a travel-friendly format, you’ll have to give up some of the power.

Another important feature is the charging speed measured in wattage. The same rule applies here: the higher the wattage, the faster you’ll achieve a full charge for your smartphone.

At last, don’t forget to check the input and output ports. You’ll need at least USB, Type-C, and Micro USB ports to ensure maximum compatibility with your devices.

10. WST 3350mAh Mini Power Bank

WST 3350mAh Mini Power Bank

Specs: Real Capacity: 3350mAh, Output Interface: Micro USB, Shell Material: Plastic, See all.

We start our Aliexpress rating with a mini power bank of low capacity – such as the WST portable battery. With a capacity of 3350 mAh, it costs less than $10, which makes it a perfect portable battery for simple day-to-day use.

Of course, don’t expect that it will be able to fully recharge your smartphones several times: according to the data provided by the manufacturer, the capacity is enough to charge a good old iPhone 7 just once. This is not much, considering how modern smartphones have evolved in terms of battery consumption.

However, the small capacity is compensated by the extremely compact size and shape: the power bank can be easily carried around even in your pocket.


9. Mlinn (Mussels) 5000mAh Portable Power Bank

Mlinn (Mussels) 5000mAh Portable Power Bank

Specs: Max Input: 10W, Output Interface: USB-A, Shell Material: Plastic, See all.

Contrary to common belief, there are small and compact power banks available on the market. In fact, there are devices designed specifically for kids, such as the Mlinn small portable battery with a varying capacity of 3000/5000 mAh, depending on the model.

It is indeed very small (just around 85x35x24 mm), comes with a handy strap, has a built-in cable, and is available in many different colors, so you can even choose a pink or blue case.

The obvious drawback is the limited capacity; you probably won’t be able to charge a smartphone battery from zero to 100% with this power bank, but it is still a good emergency option for daily use.


8. USAMS 30000mAh 65W Power Bank

USAMS 30000mAh 65W Power Bank

Specs: Capacity: 30000mAh, Max Input: 65W, Weight: About 590g, Output Interface: USB-Type C, Shell Material: Plastic, See all.

A power bank by USAMS features one of the largest capacity indicators, not only in the context of this rating but in the entire AliExpress market as well. With a capacity of 30000 mAh, you can fast-charge laptops, smartphones, and any other devices several times.

Quite often there are concerns regarding power banks with high power delivery, but this one also supports the low current mode for low-power devices.

The portable battery has one Type-C input (which is also intended for output use) for charging the power bank itself and two additional outputs for your devices: a 22.5W USB and an 18W USB.

Regarding laptop charging, the manufacturer provides specific examples: a MacBook Air 13 will fully recharge in 1.5-2 hours, demonstrating impressive power delivery.

The reason why this power bank is not as popular with customers lies in its cost and large size – it’s heavy and inconvenient to carry around.


7. Rocoren 10000mAh Magnetic Power Bank

Rocoren 10000mAh Magnetic Power Bank

Specs: Max Input: 20W, Output Interface: USB-Type C, Shell Material: Plastic, See all.

Wireless power banks are becoming more and more popular because they are much easier to carry around while offering the same capacity as wired portable batteries. As for the Rocoren power bank, it supports both wired and wireless charging, making it a perfect 2-in-1 device.

For wired charging, the power bank is equipped with the iP 18W PD and Type-C 20W PD interfaces. Having only 2 inputs might not be enough for some customers, especially those who charge more than two devices simultaneously. However, this is compensated by the compact size, thin case (just 17 mm), and lightweight construction.

As for the capacity itself, two models are available – a 5,000 mAh and a 10,000 mAh. The second one is almost permanently out of stock, so consider this a disadvantage.


6. ASOMETECH Power Bank


Specs: Capacity: 10000mAh / 20000mAh, Max Input: 18W, Output Interface: Double USB, Shell Material: Plastic, See all.

ASOMETECH’s official store on AliExpress offers three variations of this power bank: a 10,000 mAh, 20,000 mAh, and 30,000 mAh capacity, with each of them supporting 22.5W output. It means that whatever you choose, you’ll still be able to charge your phone in no time thanks to the fast charging interface.

The portable battery fully charges in 6-7 hours, which is a record compared to other power banks. Although some customers complain that, in reality, the device needs much more time to recharge fully.

The device is equipped with USB-A, Type-C and Micro USB outputs, designed to fit any of your devices – from a smartphone to wireless earbuds.

Regarding complaints, some customers noted that after a month of use, the fast charging port stopped working completely.

5. DELABO Wireless Magnetic Power Bank 10000mAh

DELABO Wireless Magnetic Power Bank 10000mAh

Specs: Max Input: 23W, Output Interface: Wireless Charger, Shell Material: Metal, See all.

Tired of walking around with a cable when your phone needs an extra recharge? Then you might consider a wireless power bank which uses a magnet to attach itself to a smartphone. You can literally attach it to the back of your phone and enjoy fast charging without annoying cables and wires – just make sure that your smartphone supports the QI (the list can be checked in the product description).

But even if your device is not QI-enabled, you can still enjoy an old and trusty wired charge. With a total capacity of 10,000 mAh, you can get 2 to 3 full charges, depending on your phone’s specifications.

Apart from this, the DELABO is small and lightweight – a perfect choice if you don’t like it when a power bank takes up too much space in your bag.

As for the drawbacks, customers report that the power bank can significantly heat up if wireless charging is used extensively.


4. QOOVI Power Bank 20000mAh

QOOVI Power Bank 20000mAh

Specs: Capacity: 20000mAh/ 3.7V (74Wh), Max Input: 45W, Weight: 431g, Output Interface: USB-Type C, Shell Material: Plastic, See all.

For a 20,000 mAh power bank, QOOVI is surprisingly affordable. While it’s priced at around $50-60, the regular discounts offered by the official store reduce the regular price to $15-25. That’s one of the best offers on AliExpress in terms of cost-performance ratio.

Regarding the technical specifications, they are quite impressive as well: this portable battery supports all the essential fast charging methods (20W PD, 22.5W QC/SCP/AFC), enabling you to charge your smartphone up to 80% in just 30 minutes.

Overheating is a widespread issue with power banks, but QOOVI features a Safe Charging system that protects both your phone and the portable battery from high temperatures during charging.

Some minor issues include a short charging cable and scratches on the power bank’s surface due to poor delivery, as reported in some reviews.


3. Essager Power Bank 20000mAh

Essager Power Bank 20000mAh

Specs: Max Input: 20W, Output Interface: Double USB, Shell Material: Plastic, See all.

Essager is a giant among AliExpress power banks, with an amazing capacity of 20,000 mAh, sufficient to recharge any phone or even a small laptop multiple times.

Moreover, it supports various fast charging protocols to ensure that your devices are recharged quickly. The manufacturer provides some examples: the USB1/USB2 outputs are perfect for charging Huawei phones (reaching 60% in 30 minutes thanks to 22.5W SCP fast charging), while the Type-C is ideal for the iPhone series, offering the same percentage of charge through 20W PD fast charging.

The only complaint is that this power bank takes too much time to charge fully. Instead of the 7 hours declared by the manufacturer, the process can take a whole day.


2. KUULAA Power Bank 10000mAh

KUULAA Power Bank 10000mAh

Specs: Max Input: 18W, Output Interface: Double USB, Shell Material: Plastic, See all.

KUULAA offers two different options for this specific model: a fast-charging power bank with an 18W output and a regular one, which is much cheaper but doesn’t support QC PD charging methods. This information is provided for your reference as we will mainly focus on the fast-charging option.

With a 10,000 mAh capacity, you can rapidly recharge your smartphones thanks to the 18W QC 3.0 and PD 3.0 charging methods. The manufacturer uses the iPhone 11 as an example: the KUULAA fast charge provides approximately 52% of the smartphone’s battery, while the ordinary power bank recharges only 20-21% in the same period of time.

Another prominent feature is a small digital display that shows the power bank’s remaining capacity. It is extremely convenient as you’ll always know when it is the right time to charge your portable battery.

While most of the reviews are positive, some customers complain about frustratingly long delivery times.


1. Baseus Power Bank 10000mAh

Baseus Power Bank 10000mAh

Specs: Capacity: 10000mAh/3.7V 37Wh, Max Input: 23W, Output Interface: USB-Type C, Shell Material: Metal, See all.

Baseus is one of Aliexpress’ featured brands, meaning that it was favorably acknowledged by customers and the marketplace alike. With more than 10,000 orders and 3,400 reviews (the majority of which are positive), it is one of the most viewed and popular power banks available on AliExpress.

The reason behind its popularity lies in top-quality performance. With an impressive 10,000 mAh capacity (the rated capacity is lower, of course), it can fully charge your phone around 2-4 times, depending on its specifications. In addition, this power bank supports fast-charging PD 20-18W technology for the iPhone series.

For Huawei phones, the power bank uses SCP 22.5W Quick Charge technology, and 30 minutes are enough to recharge about 60% of the smartphone’s battery.

Minor issues include a relatively long charging time: it requires a total of 4 hours to charge the power bank.
