    I bought this for a trip out of town which it worked awesome the only thing is that it charges your phone all whole time until the case battery is dead. With one charge at night my phone was good for 2 days the case did died first but my phone still had a full battery. There is One flaw, no way to pause or stop the case from charging the phone IF you wanted to save it the case for later.

    I’m a ride share driver and an amazon flex driver, so for me I need power all day. This battery pack surpasses all of my expectations that I had and I am truly happy with this device. You can use the same Apple charger witch is awesome. I usually have a full charge early morning from charging all night and it will last me for at least a day and a half until it needs charge. SWEET

    At first I was kind of hesitant, but after watching many reviews I decided to go for it. This charging case will fit the needs of people that might be constantly on the road or not close to a charging hub and need a quick charge. I do wish you didn't have to charge it, but hey... I think its a great thing to have. I'am very pleased with my purchase.

    This has been a great addition in providing my iPhone greater reliability with respect to having sufficient battery life and will even last me through a busy and long day. It doesn't take long to charge either because I often charge the phone and battery case separately and so charge time is the same with almost twice the longevity of battery time !

    Keeps the phone charged all day, no problem. It’s a bit heavy and bulky and doesn’t have an on/off switch... always on

    Love it. works simply. Occasionally the case doesn't charge but I think that had more to do with the charger I was using. Its soft, protective. Adds some weight (but I like that) feels sturdy. Battery with case on my iPhone works all day even with extra heavy use. Wish they had one for other models such as iPhone 8 plus because I would buy for my niece.

    Definitely a game changer if you’re constantly on the go and with little opportunity to recharge your phone. The iPhone ProMax battery is already the standard, add the battery case and you should have no problem ending the day with at least 25%. Keep in mind that’s 25% for a super user. You’ll definitely be able to go well into a second day without recharging.

    Great protection for your new iPhone 11 Pro Max. I use my phone quite often. I watch movies and listen to music. This battery case will last me 2 days without charging. It will make your phone a bit heavy, but I like the weight and it makes it feel premium. Great buy!
