You should also be aware that not all of these devices that claim to be MFI approved are. It's very easy for them to fake that information on the box. So if you're in doubt and want to make sure that the manufacturer actually does hold a valid MFI license, you can check this list. Which not only tells you if they have a licence, but what products they are licenced to produce. So if the product category doesn't appear on that list then the manufacturer may be falsely using their licence.
That list gives manufacturer names - but almost no accessories are sold directly by manufacturers.

A more useful search can be found at the licensed accessories search portal:
https://mfi.apple.com/MFiWeb/getAPS.action
where you can search by brand name, model or UPC. For example, in the accessories search, I see Amazon, Anker, and Monoprice, three brands I trust to be truly MFi certified, but none of which appear in the manufacturer list.

I entered the UPC for a backup cable I have into that portal, 670541337608, and was able to confirm that this cable is truly MFi certified, just like it says on the package.
 
i have a powerbank RAVPOWER 20100mAh with iSmart port (detects the correct amount of Ampers to push out) and i use it to charge my iPhone 7 Plus. do you think it will harm it? it charges it faster than the normal charger

should i stop using it?


Not necessarily, is it MFI? If I recall correctly Ravpower do make some MFI products.

Anyway, faster charging isn't necessarily going to be something that will damage an iPhone. They are actually capable of it within specification. For instance if you use an iPad charger with an iPhone, it will charge faster than with the normal iPhone adapter.

And that's fine, they are designed to do it. I regularly use the much higher capacity USB-C adapter for the MacBook and iPad Pro with my iPhone. Charges much faster, but it's safe because all parts are Apple and have the appropriate circuitry to communicate and deliver the correct amount of power.
So faster charging by itself isn't necessarily going to cause damage.

Even with third party products, as we've said the potential exists for them to cause damage. But that doesn't mean they will. Probably millions of people use them every day without a problem.

It's just that the possibility is there. Personally, I only use official products. But if what you have works ok, maybe your fine to keep using it and just in the future when you're buying new items, consider only the MFI ones.

I've never tried that particular model myself, though I have had RAVPower battery packs which I've used often. I always test these things with my USB power meter before I use them and I've yet to find an issue with any RAVPower one I've had.

I'd be inclined to say that you won't have a problem with it based on my experience of their other batteries, though I'd always use either Apple or a MFI licensed cable with it. But as I've not tested it myself, hopefully someone here will have had that model to give you their opinion of it.
 
I do not trust ANY cable on ebay. Not even "OEM" as I have gotten several fakes. MFi can also be faked, but you should be OK with going with a well known brand (Anker, Belkin, etc.)

I know Amazon is not a choice for the OP, but honestly those are the only cables that worked for me and lasted. I have been very happy with the Amazon basics cables.

Even with their own cables, a device behaving strangely while charging isn't unexpected or an issue. As I found out when I thought my ipad was faulty because the keyboard wasn't working properly while on charge.

That could happen if you're using a 3rd party wire or 3rd party plug. If you're using a legit wire and plug it is an unexpected issue that shouldn't happen.
I used to use a cheap Chinese ebay plug with the official lightning wire that came with my iPhone. The screen wouldn't respond to touch while charging or would act weird and only register some touches.

Nope, I spoke with Apple and even with their own cables and chargers, they can't guarantee that a device won't be unresponsive and/or laggy when on-charge.
