Best Power Banks with Pass-Through Charging

Quite compact (140x68x16 mm) external battery of the Canyon brand is an inexpensive model with a lithium-polymer battery "on board". The accessory has a plastic case with rounded sides and textured surfaces for comfortable holding in the hand. The minimalist design is complemented by a 4-level LED indicator and a power button. Canyon PB-108 is available in two universal colors - black and white.

The nominal capacity of the power bank is 10 thousand mAh, of which 6300 mAh will be directly given to mobile devices. This is enough, for example, to charge the Apple iPhone 15 almost twice or an Android smartphone with a long-lasting battery once. To replenish the capacity of the battery itself, two connectors are offered - microUSB and Lightning. The presence of the latter is no longer a must have for owners of "apple" devices, but it is still important to many.

To charge gadgets, there are two standard USB A ports with a low output voltage of 10.5 V (5V/2.1A) by modern standards, so the charging process is not too fast. At the same time, two ports can work "for output" simultaneously, and a convenient pass-through charging function and a 6-level protection system are also declared.

The disadvantages of the model include the lack of the increasingly popular Type C interface. Otherwise, if you want an inexpensive power bank with the ability to charge through, then the Canyon PB-108 is definitely worth considering.

The BASEUS brand powerbank battery is notable for its informative display. It displays data on the power charge level of the lithium-polymer battery in percent. The case is made of plastic and has dimensions of 153x69x17 mm, which does not exclude carrying in wide pockets and almost any handbag. The model weighs about 250 grams, which is the norm for solutions with 10 thousand mAh.

BASEUS Bipow 15W 10000 is equipped with four ports. One microUSB connector serves to power the power bank itself. Type C is ready to work both as an input and as an output. There are 2 classic USB ports for charging mobile devices. If necessary, three gadgets can be powered at once, plus a pass-through charging function is declared, so the lack of sockets “at hand” will definitely not be a problem.

The maximum input and output power of the charger is indicated in the name itself and is shown on the case - 15 W (5V/3A). This can be considered a standard indicator today. The disadvantages of the sub-bank include increased energy conversion costs. Thus, from the declared 10,000 mAh, 5800 mAh will actually be given, which is about 10% inferior to the capabilities of the main competitors.

Overall, BASEUS Bipow 15W 10000 is a good choice at the junction of the entry-level and mid-price segments, capable of “serving” a full set of user gadgets, including smart watches or Bluetooth headphones.

The XO brand power bank is positioned as a UPS for a router. For this scenario, there are two DC connectors - input and output - supporting voltage up to 12 V and a power of 24 and 18 W, respectively. The package also includes three adapters with different sizes - 5.5x2.5, 5.5x2.1 and 4.0x1.7 mm, which will allow you to autonomously power almost any network equipment (for example, routers or switches), video cameras with non-typical connectors "on board".

The XO PR216 is claimed to have pass-through charging, that is, if there is electricity, the model will simply pass the power through itself. And the 5 W USB A output is designed to further increase versatility. With its help, the power bank will be able to charge your smartphone or other devices, albeit slowly, because the declared power has long been considered small.

Inside the Powerbank battery there is a 10,000 mAh lithium-polymer battery. From this capacity, connected devices will receive up to 6 thousand mAh, which is definitely enough to charge a modern smartphone from 0 to 100%. The portable battery is “packed” in a stylish aluminum case. It is stronger than plastic, while being quite light (the total weight of the product is 293 grams).

The downside is the lack of USB Type C, which would make the model even more versatile. In any case, the XO PR216 is an interesting power bank for a router and/or mobile devices that do not require fast charging.

The 2025 debutant in the Belkin line is a portable battery with 10 thousand mAh. It is stated that the model will charge the iPhone 15 Pro almost twice or 1.5 times - the Samsung Galaxy S24.

One of the key benefits of the Belkin BoostCharge Power Bank 10K with USB-C Cable is the built-in Type C cable, so you don't have to carry extra wires with you.

The model provides another bidirectional USB C port. Both available interfaces support Power Delivery 3.0 fast charging technology, which will provide input and output power of 20 W. In practice, this means that the same iPhone 15 Pro will charge from 0 to 50% in just 26 minutes. When connecting two devices at once, the power characteristics drop and will total 15 W. By the way, in Pass-through mode, the connected smartphone or other gadget will also be able to receive 15 W.

The disadvantages of the model include a short built-in cable (length 5.7 cm), which is partly due to the overall compactness (99x64x23 mm). In the main scenario (paired with a smartphone), this will not be a problem, but when connecting two devices at the same time, inconveniences may arise.

Belkin BoostCharge Power Bank 10K with USB-C Cable is a solid power bank with up-to-date interfaces.

One of the main features of the Ugreen brand power bank is the presence of a platform for wireless charging. It is declared to have a power of up to 15 W, which is a decent indicator for power supply "over the air". Ugreen PB206 is also equipped with a magnetic MagSafe mount, which provides a strong fixation of mobile gadgets, and in the case of iPhone and AirPods, also optimal parameters of the charging process.

The model is complemented by a stand for a smartphone, which will allow, for example, to free your hands when watching videos or reading the news.

The power bank has two ports - an output USB A and a universal Type C. Both have adaptive support for popular fast charging protocols, including Quick Charge 3.0 and Power Delivery 3.0. With one device connected, 22.5 W can be delivered via USB A, and 20 W via Type C, reducing the duration of the power cycle. If necessary, three devices can be charged simultaneously - two with a wire and one in the wireless zone, but then the total power will not exceed 15 W.

It will take about 3.5 hours to refill the power bank's capacity (10,000 mAh). Plus, pass-through charging is available to simultaneously charge mobile devices.

The disadvantages of the model include the high price, but if you need a very functional Powerbank battery, then the extra charge for the Ugreen PB206 seems justified.
