iPhone 7 Battery Case,Powstar Ultra Slim iPhone 7 Charging Case External Battery Backup Charger Case 3000mAh for iPhone 7 Battery Pack with Lightweight (Work with Magnetic Phone Car Mount Holder)

Be clear: as in the pictures it adds about 0.4cm circumference to the iPhone 7, and of course some additional weight and depth. But you're buying a bolt-on battery case, and compared to some of the others I've seen, which either feature a passion-killing square bump on the back (even the official Apple one) or worse still a full-size USB port sticking out of one side, it is as ergonomic a solution as I've seen on Amazon, and adds grip to what is a very slippery phone without one. It's easy to get on and off so you might choose to use it only when you know you might need the extra juice, such as on an extended journey. On the juice, they rate it at 3000 mAh, and I'm not sure I've definitely clocked it as replenishing the phone 100% in a charge, but it certainly adds more than 60 or 70%, so it could be the least-hassle way of making your iPhone 7 keep going during a very long day, which it may struggle to do without any replenishment at all. Only had it a couple of weeks but so far would recommend it against similarly-priced options.

Very happy with this product so far. Arrived today so haven't had chance to test drive it, however it arrived quickly, decent packaging and the product looks good quality. Came fully charged but instructions suggest charging it for a bit longer than full for first time charge so have done this. The instructions, much like many screen protectors and cases I've had, are poorly translated but you can just about understand what they say. The silicon exterior is very smooth, something I was really hoping for!It's a tad heavy but much lighter than a portable charger and more convenient! Can charge phone while in the case and it seems to prioritise the phone before the case which is a great! I use Bluetooth earphones so can't confirm the compatibility with wired earphones.Doesn't affect the sound quality from the speakers and fits perfectly on the iPhone 7. Love how the camera is basically inverted with this case meaning the lens is protected.So far no negatives!~Edit~Two months down the line I have been very happy with this product up until now. It has suddenly stopped working. I've generally been very careful and haven't dropped the case nor gotten water in it. It has just stopped despite being fully charged. If I take the edge off and wiggle my phone a little it sometimes get a quick buzz of charging but it doesn't last more than a second and I don't want to do this too much at risk of damaging my handset. Very disappointed as I was originally very pleased.

I've given this thing a fair old shout, I've been attempting to use it for months and i have to say that i honestly think it's garbage and is now stuffed in a drawer. It takes forever to charge up, it gets flippin hot when it does, to the point i was concerned to leave it alone. It doesn't hold its charge for very long when not in use and it doesn't hold nearly as much charge as it suggests it does when it is in use.Maybe i got a duff one, who knows but i wouldn't buy another

After having this for a month or so of usage, I want to say that this is the best phone case I've ever had, at 1st I thought it was a bit chunky but now I'm totally comfortable with it, during a heavy use day, it will charge my phone right up twice with a full battery, plus it has been dropped a couple of times with zero damage.Only slight gripe is that as it uses the lightning port to charge, you cannot use headphones with a wire to listen to music from the phone whilst it is in the case, I had to buy some Bluetooth earphones for this to work (but I was planning on this anyway.Would highly recommend! 👍

Great product, no need to carry a charger or a portable charging product. Makes the phone a little thicker but it does what it says. On a negative point because the case uses the lightening port and provides another lightening port on the case my Apple EarPods don't work fully! So if you use EarPods for talking on telephone maybe not use this product.

Very very slim compared to other use chargers, i can use the iPhone lightening cable rather than a micro USB like a lot of others. Its clean and sleek so is comfortable in my hand. Would recommend.

So today it packed up on me. Neither plugging the cable in nor charging from the case would charge my phone.Less than 4 months is bad but when you consider I've been using other cases and this has probably spent less than a week on my phone, that's not good.

Lasted just over a month and stopped working. Also doesn't work with the headphone lighting adapter, you have to remove the phone from the case. UPDATE seller sent a replacement and although still working it still has the same faults as the last one and the rubber started peeling off after 2 days.
