Please tell folks to stop inquiring if a product is compatible with every known gadget. It’s taking up a lot of room. It is compatible because it is USB.

Since you charge via a USB connector, it would not matter if they purchased an older generation of the power bank that just had a micro-USB port (rather than a USB-C one).
If they upgraded to an S9, they must have kept their old phone’s micro-USB charging cord, so it’s not like they couldn’t also charge the power bank.

Can the USB Type-C port output? How quickly can it go?

This improved 3A USB C portable charger can power your iPhone up to 78% in an hour thanks to the 3A output from both the USB C and USB A ports. As seen in the video, a USB C to Lightning connection may be used to quickly charge an iPhone in 3A Turbo charge mode, and a USB C to USB C cable can be used to quickly charge the majority of Android phones.

How do you refuel?

Customers are advised to quickly recharge this 10000mAh power bank using the INIU adapter. Or, for the quickest recharge, you can select any adapter with a power rating of more than 20W. Rapid charging is not the sole benefit of doing this; it can also help avoid overheating or battery damage caused by slow charging.

Can I bring this power bank on an overseas flight?

Yes, continue only. (ten amp hours times 3.6 volts) equals 36-watt hours (TSA limit is 100Wh).
Check the label to confirm that the USB wall chargers you buy are dual voltage (110 – 240 volts/50 – 60 hertz). You should just require a basic adaptor for the country you are visiting.
Hair dryers and curling irons frequently use a single voltage of 120 volts and 60 hertz, so use caution while using them (USA). Travel versions with switchable voltage are available.

Was a wire to attach this to my iPhone 7 supposed to be included, or am I responsible for providing that?

That issue also affected me. there isn’t a charging wire to link the iPhone 7 to the power bank. not even an adapter. In response to the seller, I would like to point out that nowhere in the description or anywhere is it stated that you must provide your own iPhone 7 power adaptor in order to charge the device. If I’m mistaken, please show out exactly where it states that if you purchase this power bank to charge the iPhone 7, you must use your own charger cord AND converter.

How can I make this a charge?

It includes a short cable. That may be used to connect to a USB port. To use it to charge an Android-based phone, flip it over. You must have that cable if you use Apple. However, there is no electrical plug. You must have one that supports USB or have a USB-compatible outlet. Nowadays, this is quite a routine procedure.

Can I bring this on a plane internationally? Is it need to be in checked luggage or carry-on only? Is anyone who took this and has any problems?

Our lithium battery is 37 watt hours, but lithium batteries with 100-watt hours or less may be transported in a device in either carry-on or checked luggage.

Does Note 9 get charged?

Yes, Note 9 can be charged with this power bank. Your phone and power bank will begin charging immediately when you connect them with your charging wire.
Please be aware that the accompanying cord is a micro USB cable, which is incompatible with your phone, and is used to recharge the power bank. To charge your phone, you just need a phone cord. The QC 2.0 13.0 feature will not be supported by the power bank. Therefore, QC-design phones like the Samsung S8, S7, S6, and Note 5 may charge at their maximum rate in ordinary mode but not in QC mode.

Can I use different cords with this power bank? I’m attempting to charge a mini-USB device with it, but none of my other cords appear to work with it.

A USB-A to Tiny USB connection is required if you wish to charge a mini USB device. Connect your charging device to the tiny end (mini USB) of this charger and the big end (usb a) of the charger.

What is the battery pack’s charging process?

Simply put the battery pack into an outlet to charge it, just like a standard charger. After charging, just disconnect it. Put the USB port on the charger onto the phone to charge it, and there you have it!
