### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A battery case that is truly worth the money.
  

*by C***N on Reviewed in the United States on September 12, 2019*

I bought this as a backup to my certified Apple battery case. Turns out, this battery case is better by far.  As a bonus, this costs less than half of the official battery case from Apple. Here are some things everyone should know about this great battery case:1. This lasts longer than the Apple certified case by at least 1/3 more power provided.2. This has pass-through charging which means it will charge the phone first and the case afterwards.3. You can use the same charger for the phone for this case. Most others listed require a micro usb.4. This case doesn’t add much weight to the phone. Yes, it will make it thicker and a bit heavier, but it isn’t significant. In fact, I can get a better grip on this phone because of the battery case.The only drawback is that you have to push the button on the back in order to activate charging, but in hindsight, that should also be a plus as this will allow you to fully discharge the phone before you need it. Apple’s case charges constantly and taps the case before tapping into the phone’s battery.Overall, I prefer this case to the Apple case as it is also more durable. After a few months, the Apple case started to form tears around the top.

    Only lasted 5 weeks
  

*by A***R on Reviewed in the United States on September 29, 2020*

Spend the extra money on something you plan on using everyday... After only 5 weeks of owning it and using everyday it has stopped working. I leave it charging all night and when I take it off the charger in the morning it shows me only 1 light meaning only 25% charge. The port is messed up too, by the 5th week I had to adjust the cord at a certain angle just for it to charge. It says “device not supported” almost every time I plugged my aux cord in and had to unplug and plug back in for it to work. This case is probably only good for when you go on a day long trip to an amusement park or camping where there wont be any power outlets available. Also the buttons on your phone become super sensitive with this case on, I took about 10 accidental screenshots before getting used to it. It was good while it lasted but just poor quality.

    The case is sleek, slim and sexy (as battery cases go).
  

*by K***P on Reviewed in the United States on August 13, 2019*

Made of a matte finish black rubber, it feels good in the hand.  It doesn't add much girth as compared to what I'm already carrying, and it's anything but slippery.  Like all battery cases, it's heavy.  And that should be expected since you've just added a battery to your phone that is more than double that of the factory battery.  You should expect that this case will give you about 2.5X the battery life that you are currently accustomed to.I love that the case uses a lightning cord to charge.  Nothing I hate more than an iPhone accessory that expects me to carry some sort of extra cord just to support it.  So there is the convenience of being able to charge and sync with your existing cables and chargers.  But the bad news is that the connector inside the case isn't a lightning connector.  So while you can charge and sync, you can't use corded headphones or Apple Car Play.Since I don't typically use a battery case unless I'm on vacation, and using my phone more than normal at a place like Disneyland, the lack of CarPlay functionality isn't an enourmous problem since I'm not using it as a daily driver.  And corded headphones are SO 1980!  If you are considering this case as a daily driver, the lack of headphone and CarPlay support could be a problem for you.The case does block wireless charging, and that's just silly.  It wouldn't take much in either engineering or expense to add wireless charging to this case.  But Qi can be slow, and that's only going to complicate the already slow charging circuit in this case.Expect AT LEAST a 12-hour charge cycle at the end of your day.  And if you drained the battery completely, it could go as long as 24-hours to completely recharge both your phone and this battery case.  But this battery is so big that you are going to have to try pretty hard to run it down that far.I recommend charging the case and the phone separately if you are a heavy user.  That will help ensure that your phone starts off the day fully charged and that you get the most that you can into your battery case, too.Overall you have a good compromise of features here that should work great for most people, in most circumstances.  It's not a stretch at all to give it five stars.  The minor problems encountered won't affect very many people when put into proper context.
