    Slim Backup Battery Case for iPhone® 5/5s/SE MFi Certified (2200mAh, 1A) - Cosmic Black

    You spend a lot of money for your genuine Apple products. Why risk that investment by using unauthorized, 'gray market' accessories? The Made for iPhone logo indicates that this product has been certified to meet Apple performance standards.

    Keep your iPhone® 5/5s internal battery charged throughout the day using this Slim Backup Battery Case from Monoprice!

    This MFi certified case not only protects your iPhone 5 or iPhone 5s from the scratches and dings that come from daily use, it also provides an additional power source to keep your iPhone charged at all times. The case has a built-in 2200mAh battery, which is sufficient to fully charge the internal battery on the iPhone 5s, even when accounting for the loss due to voltage changes.

    It has built-in protection circuitry, which efficiently prevents damage from short circuits and overcharging, as well as from other malfunctions under extreme conditions. The battery can provide an additional 8 hours of talk or internet surfing time, up to 10 hours of video playback time, and up to 40 hours of audio playback, on top of the iPhone's internal abilities.

    The case can be left on, which will keep your iPhone's battery topped up, or it can be turned on when the battery gets low to get the additional boost. It uses a micro USB connection for charging and includes a micro USB charge/sync cable. It has cutouts for all the controls and connections, as well as for the camera on the back.

    One big hang up

    Pros: Lightweight, durable

    Cons: Slippery, falls out pocket or slides around easily.

    I was not happy with the product because you are not able to charge both the phone and the backup battery at the same time. When I plug it in overnight only the case charges, not the phone. I don't have a good system of charging the phone first, then the case. I would like to be able to plug it in overnight and start the day with a fully charged phone and backup battery case.

    Thank you for your review. It's a shame the unit didn't work out for your needs. Most battery backups do not allow simultaneous charging of the backup battery and a device. The main reason is that if charging the backup battery and the device at the same time it could additional strain on the battery and decrease the lifespan of the backup battery. Thanks for your support and sorry again for any inconvenience this may have caused. Should you have any questions, feel free to contact us!

    Pros: Looks nice, fits well. Does a great job bringing more battery life to your iphone 5 or 5S.

    Cons: Don't know if I got a somewhat defective unit or not but the USB micro jack will not securely hold the USB cable once plugged with many different cables I always have to position the unit in a special way to get it to start charging and the slightest bump will dislodge the charge cable.

    Does the job

    Nice style

    Pros: Will recharge your phone when no power is available. Style.

    Cons: Will not charge your phone when it is charging.

    When plugged in it shows that it's charging your phone as well yet the battery percentage goes down. It must only trickle charge. Same thing still happens when battery pack is full. P.S. Using a 2.1 amp charger so that is not it.

    Great product not military grade protection

    Pros: Solid, polished construction. Great battery life.

    Cons: Not for high-impact uses.

    I really like the battery case, and if you primarily work in an office or some other white collar job, it's probably terrific. However, I work in a job where my phone often gets bounced around a bit, and the case does not protect the phone on all sides. The case is solid, but I would probably not recommend it if you're working in a blue collar type job where it might see some abuse.

    Outstanding Deal

    Pros: One piece case that slides. Keeps you from losing the top piece. Open design directs audio forward. Open access to headphone jack. Don't need extension except for bulky right angle plugs.

    I just dig everything Monoprice. Their first iphone 5s battery case died after six months, but it was still a steal because at three times the price, Mophie and Phone Suit died too. I think they really pay attention to performance, engineering, and price equally.
