The USB-C port of the power bank is suitable for both input and output. The power bank supports Power Delivery 2.0 and 3.0, which means that it can both charge and charge other devices.
The power bank switches off after about 30 seconds if the power consumption is too low, as it requires a minimum current to continue supplying power. For this power bank with 15000 mAh and 30 W output, the required minimum current is typically around 100 mA to 200 mA so that it does not go into switch-off mode. If the Arduino draws less current, the power bank recognises this as an open circuit and switches off.
To operate the Arduino continuously, the current consumption should be at least in this range or you can add a load (e.g. a resistor or another device) to increase the current requirement and thus prevent the switch-off. The power bank also supports adaptive fast charging technologies, which means that it can respond to different loads, but too low a load will result in shutdown [product data].
Mathematically yes, because the power bank has 55.5 Wh and your camera battery has 16 Wh. In practice, however, you have to reckon with conversion losses, so 2 to just under 3 full charges are more realistic and not 3 full charges for sure. Charging with the Sunslice Fusion Flex 12 should work in principle. The panel delivers a maximum of 12 W via USB A with 5 V and 2.4 A and is also suitable for charging a power bank according to the manufacturer. However, it will be rather slow and will depend heavily on the sun and orientation. So it is useful for travelling, but not particularly fast.
I tried it out today. The esp32 has been running for three hours without any problems. The charge status LEDs remain permanently switched on. However, I can't say whether it would run like this for a week.
Yes, the power bank is MagSafe compatible. It supports magnetic charging for iPhones with MagSafe standard from iPhone 12, therefore also for the iPhone 17.
Yes, you can charge a Lenovo laptop with 65 W with this power bank. It is explicitly suitable for notebooks and supports Power Delivery 3.0 with up to 140 W output power via the USB-C ports, which is more than sufficient for 65 W.
Yes, you can use it to charge your Windows laptop. The power bank has a capacity of 99.36 Wh and supports Power Delivery 3.0, which is sufficient for laptops with 65 W power consumption.
The power bank is explicitly suitable for laptops and has two USB-C ports with Power Delivery technology, which ensures a stable power supply for your laptop. With an energy capacity of 99.36 Wh, you can fully charge your laptop several times, depending on the model and usage.
CCC verification is not absolutely necessary for private trips to China. Confiscations are more likely to happen if the device is not in hand luggage or if it is not clear how many mAh or Wh the bank has.
Yes, this is exactly what happens to me as well. With a capacity level of 41%, over 20 hours of remaining time are displayed, but after three hours it stops, i.e. you can't rely on the display. I will be reporting my device for servicing shortly.
It's also a shame that you can't set the device to stop charging when the charge level reaches 80% in order to conserve battery life.
As long as you don't try to charge the power bank at the USB-A port, you're probably not doing anything wrong. If it is working, you will normally quickly see the Digitec logo on the screen, followed by the charging power. If you press the button (perhaps for 10 seconds), will nothing happen?
I was able to carry out a search and clarify this with the relevant department. In principle, we or manufacturers of products sold in Europe (including Switzerland) must comply with the regulations applicable here and label them accordingly. Unfortunately, the CCC certification applicable in China is not part of this and is not labelled as mandatory, regardless of the country of production. In such cases, it is recommended to know the regulations of the destination country before travelling and, if necessary, to purchase a compliant product there if your own products cannot comply with the regulations. Of course, for products such as laptops, smartphones etc. it would be nice if they fulfilled all the world's regulations or if the countries could agree on a certificate, but unfortunately the reality is much more complicated and we have no influence on this.
The power bank fits on a Galaxy S25 Ultra with MagSafe, as it is MagSafe-compatible and therefore adheres magnetically to the device. The Galaxy S25 Ultra supports MagSafe accessories thanks to the built-in magnetic ring, which enables wireless charging and the use of MagSafe accessories. This guarantees the connection between the power bank and the Galaxy S25 Ultra.
The magnetic power bank is MagSafe-compatible and therefore suitable for the iPhone 13 mini, which also supports MagSafe. The power bank is specially designed for smartphones with the MagSafe standard, which enables a suitable magnetic attachment. The dimensions of the power bank are designed to be compatible with the iPhone 13 mini, which is 64.2 mm wide and has a compact design.
With a capacity of 5000 mAh and a weight of 130 g, the magnetic power bank is compact and MagSafe-compatible, which makes it fundamentally suitable for the iPhone 13 mini. The iPhone 13 mini measures 131.5 mm in height, 64.2 mm in width and 7.65 mm in depth with a weight of 141 g. In terms of size and weight, the power bank is therefore well compatible for magnetically attaching to the iPhone 13 mini and charging it on the go.
As this power bank is manufactured in China for Digitec Galaxus and is only intended for export, there is no CCC certificate. Presumably the same power bank is manufactured for the Chinese market with a CCC certificate, but you will probably only find it in China. In my experience, Chinese companies do not bother to certify products intended for export.
