Can you also charge a tablet (iPad Air) with it?

how long does it take to charge an iphone 7 plus and how often is this possible?

I bought this 4 months ago, now it no longer charges the phone, it takes so long and doesn't charge, can you tell me if this is a problem with the charger or phone? Good :) I changed the cable and now it works as before.

Is this model the same as article 11000819?

10Ah? I don't think so. I've got two of these things and I'm still testing with a third. My OnePlus 7 pro has a 4000mAh battery. Theoretically, I should be able to charge the OnePlus at least twice with this PB. If we add a little loss, then it should be an even two times. BUT I can charge it exactly once. Then the charge indicator is at one bar. Either the PB never has 10Ah, or the power loss is so high that it is only enough for once. I rather believe in the second one. Because with this much power loss, the PB would have to get extremely warm... *correction - of course I believe in the former.

Can I use the powerbank to charge my iPhone X? charge?

What is the difference between this product and Samsung External Battery Pack 10000? Do I have to buy an extra cable to charge the Samsung External Battery Pack?

Do I need an extra cable or can I just charge it with my iPhone cable?

Is the mains plug with transformer included?

Does the part also work for the iPhone? (I have an old SE).
