I am a great fan of battery cases. I don't like to carry a separate power pack and I certainly don't like either running the phone out of power or having to charge wherever I am! In addition, with my iPhone 11 and a Destek brand case, I dropped my phone inumerable times without a single scratch or crack and I was not using a screen saver. This case is a bit harder than the Destek but it should protect my new 16 Pro Max well. It is supplied with a screen saver and I gave that a moment of thought but I didn't use it. YMMV. Insertion of the phone was straight forward. Be VERY cautious not to bend or TWIST the phone when doing this. A while back, my iPhone XS Max (series X) decided to ghost dial (dial on its own) my contacts in the middle of the night! I am pretty sure I was too rough on the phone when inserting it into a somewhat difficult power case. This case is easy and soft but still be careful. All in all, I love this case but I dropped one star because the feel of it is a bit hard and the Destek I had was softer. Unfortunately, Destek does not make cases for newer phones.

The case construction is OK for the price. Its not a high end product, but you also don't pay for it. I'd dare say, cheap and you have to be very careful putting your phone in. This is not a very durable item. Be careful.It adds significantly to the profile of your phone. Yes, still pocketable, but it's a big bulge now. Weight is definitely an issue.Functionally only a part way there for me (compared to what was promised). But I feel the value is fine for the price. Just note the above.Charging is as fast as the stated 15 watts as expected.However, the 8500 capacity battery life appears to be just enough to add maybe 80% to the use of my phone only. Definitely not 150% (2.5x battery life) - I'm talking starting at 100% + 1.5X charge, as it indicates.I think what is happening is the battery or setup may be affecting the reception capabilities of the phone, thereby increasing the amount of power needed for 5G / Wifi etc. But it could also be the charging efficiency from the pack to the phone. Or.... maybe I managed to break it trying to get my phone in one time.For myself, I'd likely spend more money for a better product.

This powerbank fits my Iphone 16 Promax phone. It extends it battery life to the whole day, and it is not that bulky. It also come with a charging C-connector cable for you to charge it. Charging it to full strength is very fast, completed in about 2 hours. However, it double that time if my phone was low in battery, and you have to charge both at the same time. By simply plugging the phone to the powerbank , you can immediately start using your phone again while it was being charged. The protection function is just ok as it does not covers the corners completley. It does add to the thickness of the phone. I like to have this insurance as the battery does discharge quite fast under full use without this powerbank. It comes with two screen protectors, because it is a little thick I decided to use it without it.

I had purchased this battery case under the belief that it would fully charge my phone from the fully loaded battery, but it only reaches 66-68% charge of the phone when the case battery drains, a clear case of a product underdelivering on its promise. (I also got another replacement battery from the manufacturer only to confirm that it charges to 2/3 full despite the mfg rep's claims to the contrary).

This is a great case. The quality is wonderful and a perfect fit for your iPhone. Your phone will be very well protected. Grip is excellent on it. Great design and value for the money. The battery life is wonderful. It is super functional especially for traveling.

The life it adds is amazing. I don't care about bulk, or weight so much.I'm from the days where you could have five batteries ready to go. You never hugged a wall.Since we as a society are going backwards in tech, we are forced to be plugged in constantly. Waiting for a full battery is EXTREMELY annoying, and let’s be honest, not very safe (dead battery, & lost)I love this charger case. I would like to have several to go back to the days of swap and go. It fits well. It charges the phone. Keep in mind the case has priority over phone when plugged in. You should plan for this. It doesn't bother me because I'm a sleeping charge person. When I get more cases, I'll have a lil battery army for my day :))

This battery case fits my iPhone 16 Pro Max perfectly. It recharges my phone very quickly so I can take it off after recharging. It does make the phone a lot more bulkier so I would not recommend using it daily. I think it is perfect for holidays or day trips so I can recharge the phone on the go without connecting to a power bank via a cable. The battery case is well-made and feels good quality. It is priced at £39.99 at the time of review, which I think is a little expensive as it is much more expensive than a power bank of a similar battery capacity, hence it's a 4-star from me.

Really solid battery case! The 8500mAh capacity keeps my phone going for ages, and it’s slim enough that it doesn’t feel bulky. The blue colour is a nice bonus too. Definitely recommend if you’re always running low on battery.

In the box you get the case, usb charge cable and even a screen protector.Typically these cases are 5 to 6,000mah. This a whopping 8,500mah.Easy to fit, just make sure you slide the phone in with power connector inline with the phone port.Its nice and grippy so should help you to not drop your phone.Charges quickly. And realistically you should even as a power user, get 2 days usage with this fitted.Good protection and loads of extra power from this case. Not too bulky in your pocket either.Recommended.

I am not always a fan of these battery cases, but in this case (haha) I am a fan!With the already big iPhone 16 Pro Max I was afraid this case would weigh as much as my car but that is not the case!Nicely design, strong connector and easily fit onto the phone.Huge capacity for a case like this.Charges easily and triples your capacity - great for days where you need to be able to take photos/videos all day without a charger.Recommended!
