Chapter in this post:
A few weeks ago I already had them for you Anker PowerCore 10K Wireless presented. This model has Qi charging and a USB-C port as well as two USB-A ports. However, the USB-C port on the "old" model is only an input for charging the power bank.
The new model called "Anker PowerCore III 10K Wireless“Anchor made available to me again free of charge for a test. The main difference for me is that the USB-C port is now both input and output and the Charging standard USB Power Delivery supported. The maximum voltage is 9 volts.
In addition to the power bank itself, the scope of delivery also includes a USB-C charging cable and a transport case, which - well padded - prevents the additional battery in the backpack from being damaged.
You can translate the term with the German word “preservation charge”. This means that a consumer is continuously charged with little power in order to maintain its charge.
In the case of power banks, however, the trickle charge mode is intended for devices that consume very little current, with the current being well below 0,5 amps. True wireless headphones, smartwatches and the like come into question here. The AirPods, for example, fall under this category of consumers.
In order to be able to charge this type of device, you hold the button on the Anker PowerCore III 10K Powerbank for approx. 2 seconds until one of the LEDs on the side lights up green. Now you plug the corresponding device with a charging cable into the power bank and it is charged continuously without the power bank switching off at any time when the charging current becomes too low.
The USB-C port can be used to charge devices such as the iPhone and iPad. Unfortunately, it (almost) does not work with the MacBook or even a MacBook Pro - but more details on this below.
Nevertheless, the power bank with 18 watts offers a high output power that I usually only know from 26.800 mAh batteries like the Zendure A8 PD. However, this is firstly in a different price segment and secondly is also aimed at a different target group - namely people who travel a lot with MacBook or iPad. Anyone who falls into this category can get the Zendure A8 PD maybe take a look.
With the Qi charging function, you can generally charge anything that is compatible with this charging standard. I mainly use it for my iPhone Xs and the AirPods Pro. What is often asked, but still does not work: charging the Apple Watch via the Qi charging pad. Apple has developed its own charging standard so that you can use the special Apple Watch charging cable is instructed or one Apple Watch power bank like Terratec Charge Air Key uses.
The 10 watt output power that the Anker Powerbank offers for wireless charging also supports the fast Qi charging that the current iPhone models enable. So here you are also equipped for the future and can charge as quickly as technically possible, both with cable and wirelessly.
When I had the PowerCore III 10K Wireless in my hands for the first time, I still had question marks on my forehead when I saw the pull-out plastic part. After reading the product description, I was smarter: This is a holder with which you can clamp the iPhone in portrait or landscape format to the power bank, for example to watch films while the power bank is charging the iPhone.
The idea alone is worth praise. I can't say how often you use this feature in everyday life, but it definitely makes the power bank more versatile than many other additional batteries.
As a test, I charged my iPhone Xs via the USB-C port. After a short time, the charging voltage jumped to the 9 volts that you would expect when fast charging the iPhone. The charging power was around 12 watts.
For comparison: The small Apple power supply unit that used to be delivered with the iPhone (USB-A) only manages 5 watts and even the Zendure A8 only charges the iPhone with approx. 9 to 10 watts via USB-A. With the USB-PD of the PowerCore III 10K Wireless you are very well served.
The iPad Pro (12,9 inches) could also be equipped with the Anker Powerbank. Here I came up with an output of 17 watts (at 9 volts). With 9 volts, the power bank has delivered the maximum voltage and ensures that the large iPad is charged quickly. It is only faster if you have a USB-C power supply with Power Delivery that delivers 15 volts. Then, according to my measurements, the iPad Pro consumes up to 23 watts and is charged a little faster.
Unfortunately, the Anker PowerCore III 12K wireless cannot do much with the MacBook (10 inch). The USB multimeter shows approx. 11 watts (at 5 volts) flowing into the MacBook.
During operation, the MacBook shows "Battery not being charged" in the menu bar for the charging icon. When measuring with CoconutBattery it turns out that the battery of the MacBook is still charged slowly - namely with approx. 4 watts.
In an absolute emergency, you can perhaps increase the battery level of the small Apple laptop with the power bank by a few percentage points - but that is not serious charging.
With the AirPods, it's hard to tell how fast or slow they charge. In any case, one can assume that they will charge the battery more quickly via a cable than via wireless charging.
I have both ways with the AirPods 2nd Gen (wireless), the AirPods Pro and the Ear Fun Air tested. All devices used the electricity themselves for wireless charging and filled the battery.
The PowerCore III 10K wireless battery is great for people who use various Apple devices. While you can quickly charge the iPhone via the cable, you can fill the AirPods via wireless Qi charging.
The output power is very good and the capacity for smartphones and headphones is sufficient. If you want to supply an iPad or even a MacBook Pro with power from a battery, I would use the Anker PowerCore + 26800 guess with USB-C-PD and 45 watt output power.
Otherwise, the 10.000 mAh power bank I tested is Anker PowerCore III 10K Wireless a good - and not so difficult - companion on excursions or when traveling. You have different connections and charging options and you don't even have to have a cable with you for iPhone and AirPods.
