There has been a small revolution in charging technology not so long ago. GaN chargers have appeared on the market, which deliver unprecedented power at their relatively modest size, which became possible thanks to the use of gallium nitride, instead of the previously used silicon. GaN chargers are more powerful, more compact, run cooler and generally withstand higher temperatures. Today I will show you a 45W GaN charger from Baseus, which is also a 10,000 mAh battery. The solution is very interesting, before you are both Power Bank and charger, and with support for all fast charging protocols.

In general, Baseus has different GaN chargers and this is far from the most powerful. For example, there is a charger for 65W and even for 120W, but it is the 45W model that, in my opinion, is the most interesting. Its power is enough even for fast charging of a laptop and at the same time we get a bank with additional energy, with a capacity of 10,000 mAh. At the same time, the physical dimensions are quite standard and are comparable to a MacBook power supply.

The device comes in high-quality packaging, designed in the same design for the entire Baseus brand.

We see that support for all fast charging protocols is declared, such as:

  • Power Delivery 3.0
  • Quick Charge 4+
  • Quick Charge 3
  • Adaptive Fast Charging for Samsung
  • Huawei SCP
  • MTK PE +

On the back there is more detailed information about all supported modes, for convenience I will duplicate them.

In charger mode :

  • Input: 100V-240V AC, 50/60 Hz, 1.0A
  • Type-C Output: 5V / 3A, 9V / 3A, 12V / 3A, 15V / 3A, 20V / 2.25A Max
  • Type-C + USB Output: 30W + 15W Max
  • USB Output: 4.5V / 5A, 5V / 4.5A, 9V / 3A, 12V / 2.5A, 20V / 1.5A Max

In Power Bank mode :

  • Type-C Input: 5V / 3A, 9V / 2A, 12V / 1.5A Max
  • Type-C Output: 5V / 3A, 9V / 3A, 12V / 2.5A, 20V / 1.5A Max
  • USB Output: 4.5V / 5A , 5V / 4.5A, 9V / 3A, 12V / 2.5A, 20V / 1.5A Max
  • Type-C + USB Output: 18W + Maximum 18W
  • Battery: Li-Pol 10000 mAh, 3.7V 37Wh, rated capacity 5800 mAh (at 5V / 3A)

We continue unpacking.

Inside are neatly packed: charger, cable, cloth bag and documentation.

Since the device involves frequent movement and use on the road, for the preservation of a presentable appearance and transportation, it was equipped with a simple bag with ties.

I am pleased with such attention to detail and protection of their products.

Also, the right decision was to put your own proprietary cable in the kit, which supports standard fast charging and is able to pass energy through itself with a power of 45W.

Well, and various documentation, including: user manual, warranty card and a memo to the buyer. As a bonus — a set with branded stickers.

Outwardly, the power supply looks interesting and is comparable in size to a regular Power Bank of 10,000 mAh. On the case we have a power button and 4 LEDs.

By pressing the button, you can estimate the remaining battery charge, one bar corresponds to approximately 25% of the charge.

During operation, the display is constantly on. If the device is operating in one of the fast charging standards, then the lowest LED changes to orange.

On the reverse side, everything is clean.

The plug is European, but if necessary, it can be American (selected when ordering). Here I see some kind of constructive flaw, they could have made the plug detachable, so that when traveling, they could change it to the desired one.

Connectors were placed on the end.

In my case, this is a universal Type-C connector that works for both input and output and additional USB. If you need 2 Type-C connectors, then this option is also available when ordering.

Well, for a better understanding of the dimensions, against the background with a smartphone:

And now some tests. The tester determined the presence of Power Delivery and other modern fast charging protocols, only QC3.0 did not. In fact, the charger can supply any intermediate voltage from 4.5V to 20V, so it can be used in conjunction with any type of device.

Well, then, using an electronic load, I checked all the declared modes for maximum currents in the charger mode and in the Power Bank mode. 5V / 3A

9V / 3A

12V / 3A

15V / 3A — here I already ran into the possibility of my load, because it is designed for a maximum of 35W and is simply not able to pull out more from the charge.

20V / 2.25A — similarly, my electronic load rested against the ceiling and cannot “pull” more from the charge.

In real use, too, everything corresponds: a laptop and another Power Bank with support for Power Delivery mode — charges. Pass-through charging mode — supports, that is, you can simultaneously charge your built-in battery and power or charge other devices. Another point that may be useful to someone is the mode of automatic switching of power from the mains to the built-in battery. For example, you energized something, leaving it to work on its own and your electricity goes out (let’s say a camera is a recorder). In this case, the power will automatically transfer to the battery, that is, in fact, the device can be used as a reserve to ensure uninterrupted power supply to the devices.

Now regarding the charging speed of the built-in battery and its capacity. Having discharged it completely, I put it on charging through the network, I measured the charging time purely physically, looking at the indicators every 10–15 minutes. As a result, it took almost 3 hours to charge . For the experiment, I also used the type-c charging method, connecting a third-party charger. The best I have found is the 18W charger with Power Delivery support. For the first 2 hours, charging was carried out with a voltage of 11.85V and a current of 1.57A, that is, the power was actually 18.5W. After 2 hours, charging first went into 5V mode, and then it rose to 6.5V, mirroring the current drop. But in the end, it took 3 hours 25 minutes to fully charge ,which is actually even more than when charging from the mains. Therefore, do not engage in nonsense and charge from the outlet.

Well, the last test concerns the battery capacity. Declared 10,000 mAh or 37Wh, nominal capacity (that is, how much it can give) — 5800 mAh (at 5V / 3A). In my case, the battery gave 35 Wh or 7076 mAh. It is a little unclear how it turned out less capacity in Wh with a larger capacity in mAh, but in general the capacity corresponds to the declared one. This I discharged with a current of 1A at a voltage of 5V.

At high voltage, the picture will of course be different. For example, here is a graph at 12V. At some point, the device warmed up and automatically switched to 9V, the total drained capacity was 31.2 Wh. Well, in general, I think it is clear here that charging a smartphone with a 3.7V 5000 mAh battery is not the same as charging a laptop with a 7.6V or 11.1V battery. And if you can fully charge the smartphone, then the laptop is only half or even a third.

That’s probably all. The device fully complies with the declared characteristics and is suitable for “portable” use, ie when you need not only to quickly charge or power your home device, but sometimes do it on the road using the built-in battery. If the built-in Power Bank is not needed, then Baseus has a more compact GaN charger, and if you need a more powerful one, Baseus has such a 120W GaN.
