Color: BlackVine Customer Review of Free Product( What's this? )
I'm only rating this case as 3 stars because of several factors:
*First,the product information is somewhat contradictory. While it says "extend the battery life of iPhone 4/4S to almost a full charge", the chart comparing models lists this one as providing "More than 2 times the run time".
*Second, I don't like how the case is constructed. The case has a seam around its perimiter where the battery pack meets the sides of the case that wrap around the phone. This is a point of failure and just doesn't look all that great.
*Third, the led's are hard to see and the top of the case near the power button has some slack, which makes it look a bit odd.

On the up side, the case does do a good job of protecting the phone and providing backup power. Buttons are easy to use, it charges quickly and charges the phone quickly, too. Doesn't get too hot while charging, which is good. It's comfortable to hold and has a nice grippy feel to it. Also, since the perimiter is fairly thin (but not too thin) rubber, the headphone port is easy to access, as is the mute switch.
In my use, I put this case and my phone through several full charge/discharge cycles. I've found that from a completely dead battery, this case will provide a 75% charge to an iPhone 4. It could be a bit more or a bit less depending on how much use it gets while charging from the case.

I did a monitored charge and here's the results.
-Started off with both phone and case 100% charged.
-Ran the phone dead until it switched itself off and only displayed the "charge" icon when trying to power on.
-Flipped the switch of the case to start charging.
-At ~4 minutes the phone was at 5% and able to be powered on
-At ~30 minutes, phone at 37% and battery case had 2/4 lights remaining
-At ~65 minutes, phone at 76% and battery case was dead.

While the case protects fairly well, it is big. This is expected of all battery cases, and you simply have to trade this off. The back of the case where the battery sits is obviously very rigid, but the problem is that it's then glued to the rubber that surrounds the phone. It just looks like the seam can separate, and in fact it started to when trying to take the phone out of the case.

Speaking of putting it in and out, putting it in is really easy, but removing it is a real pain. You have to try to tilt the top of the phone out of the case while pulling it out of the dock connector. The problem is that there's no way to grab the phone or get your fingers behind it to tilt it. Don't get this case if you'll need to remove it from the case often.

If you have a lot of iPhone docks, rethink this case. Like most battery cases, it conseals the original Apple dock connector and replaces it with a micro usb port on the side. Since it's difficult to remove from the case, it will not be easy to slip out and place in a dock.

If none of my frustrations are applicable to your needs/expectations, you might find this an ideal choice. Otherwise, maybe check out some cases by Mophie or other brands for comparison before you buy.

This item is an iPhone 4/4S compatible charger and battery that's in the shape of a thicker, substantial case. Of course, being an actual charger/battery contributes to the 3 oz. weight of the case (my iPhone 4S weighs 4 3/4 oz. as reference). The case comes with a micro usb cord, but you'll need to use your own plug adapter for the wall socket (like the one your iPhone came with)

The Appearance and Design

The case is made of a high quality, "grippy" feeling material that does not hold fingerprints and is matte. The Energizer label is stamped in the front/bottom of case in a slightly shinier font, which can be seen mainly in certain angles in the light. There is a 30 pin male connector at the inside bottom of the case, into which the iPhone docks when the cover is fully in place around the phone. A micro usb port is on the outer side, bottom right of the case, and the regular iPhone charging pin port is inaccessible. Effectively, the charging case converts your iPhone from needing the proprietary Apple connector to the more prevalent (well, at least i have more of these laying around) micro usb. This would not be a great feature, however, if you have a lot of accessories using the Apple proprietary plug. On the outer side, bottom left of the case is the case's own on-off switch, which allows you to determine if and when you will access the case's backup battery power. The other 3 "cut-outs" in the case include the area where you plug in an earpiece, the camera lens, and the ringtone mute switch. The volume controls and power buttons are covered, but engraved on the case (work well pressing through the case). The back of the case is tapered in an angle to better fit your hand, and it feels good to hold the case. The front "lip" covering the rim around the front of your iPhone is not as high or pronounced as on other plain cases i've used, so i can see that if you dropped your iPhone on its front, there could be more potential to get a scratch or crack. Still, i'm glad it's not too pronounced, since the case is fairly bulky already, due to it's other functions. On the outer side bottom of the case, there are up to 4 subtle, internal, and blue-colored circular lights that show the charge of the case itself, but only appear when you plug the case in.

The Functionality

The instructions say that the case is pre-charged and ready to use out of the box, however, you'll probably need to charge it first, as I found when i tried to charge my phone with the case upon receiving the unit. I placed my iPhone in the case, slid the case's on/off switch to the on-position, and the iPhone started charging from the 51% level that I had left. I saw that the bottom of the case showed one blue light, blinking, indicating a low battery level for the case. At 8 minutes, I saw the phone wake-up and stop charging, no blue light on the bottom of the case, and the phone had charged to 64%- pretty quick, i'd say. I plugged the case (with my iPhone in it), to the included micro usb and a wall plug, and the phone resumed charging and the case had 1 blue light blinking again. The instructions indicate that when plugged in this way, the iPhone will charge first, and then the case will charge- in sequence, not at the same time. The following lists my first charging attempt- sorry if the times are a bit random- i checked sporadically.

0 minutes- 51% phone charging from new, out-of-box case w/o plug-in
8 minutes later, phone at 64%, no charge left on case (no blue light)

plug in case with phone to wall socket

30 minutes - phone 84%, one blue light blinking on case
45 minutes- phone 93%, one blue light blinking on case
2 hours- phone 100%, one solid blue light, second blue light blinking on case
3 hrs 10 min- phone 100$, 2 solid blue lights, third blue light blinking on case
overnight, and about 8 hrs later, phone at 100%, 4 solid blue lights.

At this point, i turned off the case's on-off switch, to ensure i could have the full case/battery back-up power available (only about 85% of the iPhone's full charge is available in the case/battery according to the packaging info). It's still holding 4 solid blue lights after 12 hours.

The case charged my phone really well, fairly quickly, and i'm happy to have the extra power available without carrying other charging devices. The extra weight of the case is outweighed (ugg) by the benefits, and it's a nice looking case cover to boot.

tip: i also tried to remove the phone from the case as another reviewer had tried, and was able to extract the phone (not too hard to do once you get the hang of it) from the case by lifting the top lip on the front of the case, and pressing with a pencil eraser on the camera lens (there's a cut out) to push the phone forward. From there, i pulled it off the docking. It's probably not great to press on the camera lens part, but it's a working way to remove the phone- just fyi.

Batteries can be the bane of our existence, but this battery/case stands out as a very handy addition to enhance practical usage of an iPhone.

This case provides a very specific intersection of protecting the phone and doubling its operating time. The only cons are the lack of a screen protector, and the blue LED "power capacity" indicators, which are hard to see in daylight.

Its usefulness would become apparent if you were planning a series of extended, power-challenged excursions. Having the case charged and ready to go for a camping or a car/plane trip would seem like the most beneficial scenario.

Charging times for me, with the phone starting at a 5% charge were, impressively:

0:30 to 50%
1:15 to 95%

As an Otter-box owner - which is still the ultimate in protection - I know many people consider this level of physical protection overkill. The Energizer case is one step down in protection from the O-box (and you need that separate screen-protector). The battery case's width is slightly thinner than the O-box, but overall it's slightly longer.

Getting the iPhone out of the battery case is not trivial. Using a pencil's eraser end to help push the phone out worked for me. Since the surround is more plastic than rubber, it holds its shape very well. My otter box, after only a few cycles of ejecting and reinserting the phone, shows signs of stretching.

Definitely a good-value "accessory" for the iPhone.

My husband's iPhone 4s is always low on battery, so I thought this might be a great solution for his battery woes.

Pros:

- Protects the phone well
- Does what it's supposed to do: provides a backup power source for the phone
- Charges relatively quickly
- Holds a full charge for the iPhone 4 in the battery

Cons:

- Adds some bulk/weight to the iPhone profile (but really, if this is a serious issue, you shouldn't be looking at battery cases because any case is going to do this)
- Very difficult to get off. This case is made to stay on the iPhone 100% of the time, not taken on and off as needed. If you want to sync your iPhone or charge it, you have to do so through the mini USB port on the side of the phone. This is all good and well, but if you have dock accessories (such as speakers) you want to use your phone with, getting that case off is a real ordeal.

The bottom line is that this works and does what it promises to do. The issue comes when you don't want to leave the phone in the case all the time; it's a real bear to wrestle out, and because of this, it's now languishing in a drawer rather than being used on a regular basis.

TOP 500 REVIEWERon May 2, 2013
I found this case at a local retailer in the clearance section, and now I know why. While I'm sure the charging functions work fine, I'm going to return this case because:
- It is bulky, making the iPhone about twice as thick. To be fair, I kind of expected this as they need the room for another battery.
- I personally didn't like the "feel" of the silicone material this case is made out of
- I had planned to use this as a temporary case, only putting it on for occasions when I'm going to be away from a power source for an extended time (hiking, all day concerts, etc). However, it is nearly impossible to get your phone out of this case! It took me at least 30 minutes to "roll back" the silicone enough to eventually rock my phone loose from the charging connector.

This case seems too bulky for every day use, and since my idea of only putting it on when needed is out the window, this case isn't going to work for me. However, if you're daily routine has you constantly away from a power source and you don't mind the bulk, this case may work out better for you.

Color: BlackVine Customer Review of Free Product( What's this? )
In the package:
Charging case
Micro USB to USB charging cable
Card instructions in English & French

Style/Looks/Quality/Access Points:
This case is thick rubber style that fully hugs your phone on the back & all side & a very small part of the front.
It's a basic industrial modern design that isn't stylish, just functional as you never have to worry it will fall out.
The way it overlaps a small part of the front of the phone is loose, not so it will slip out, but that it looks bad.
The seams on the inside look like they are SUPER-GLUED together & even though I only installed/removed it ONCE, I already see them tearing apart on the sides. Pulling back to look has made it rip almost to a complete hole.
Case Access Points:
The phone's buttons are fully covered by the rubber case & the rubber button overlay works flawlessly.
There's a hole for the back camera & flash & have not noticed an issue taking pictures.
The bottom speaker/mic are covered on the bottom & there are holes on the front of the speaker which work great.
The top 3.5mm headset jack is exposed well & the hole is large enough to connect even larger rubberized headset jacks that other cases could not fit.
Indicator:
There are 4 dim LED lights on the bottom that light up when you push the bottom button to indicate how much charge is left on the case.

Installing/Removing:
Do not use this if you mind that you're phone will be much thicker/heavier as installing it is easy, but removing it is very difficult. If you have to remove it more then a few times, the seams WILL rip. BTW, I did as you are suppose to do: peal back the top & then pull out the phone upwards. I have ripping on both the top AND the sides. (I am a short woman with small to medium hands who treats her things with care.)

Product Specs:
Battery: 1700 mAh Lithium POLYMER
Input: DC 5V 500mA/1A
Output: DC 5V 1A

Usage:
Instructions states,
"Your phone will be full charged in 2 hours or less." and "Your case will be fully charged in 4 hours or less."
"When charging it will always charge your phone first, then the case."
"You can sync your iphone when you plug in the micro USB to USB cable to a PC."

When I charged my iPhone, it got VERY hot, even almost too hot touch touch on the back of the phone/case. I was worried I was baking my iPhone. This happened each time, though I tried to keep the phone standing or laying on different surfaces trying to keep down the heat, even having it stand up vertically.
I did like that it DID charge faster then I expected & when I let the iPhone drain completely & only charged ti with the case, I got almost 80% battery back.

This Energizer hanger is an alternative to the Mophie battery pack. This item perform well and charged my phone about 70% of the way. The issue with the charger is removal. It's damn near impossible o remove. There is no area where to get enough leverage to hold and remove the iPhone. Absolutely horrible in that regard.

I wanted a case for my son and his new iPhone 4S.....and I've always been pleased with the Energizer products. GREAT, sturdy case that fits VERY securely around the phone. Seems to be made with very durable rubber....and of course extending the battery life of the energy-demanding iPhone is a major plus. In the interest of maximum protection, he wants an otter box....but this case makes for a great alternative.

There is a nice convenience to having a charger pack around your iPhone 4(S) (only fits the 4 and 4S) that can actually help protect it. It does fully charge in only a few hours and gives you almost (not quite) a full charge. The four blue lights on the end let you know how much charge is left. Everything about this seems pretty cool, but there are less expensive products out there that have almost four times with as much chargeable energy.

PowerGen PGMPP9000 External Battery Pack High Capacity 9000mAh Power Bank Charger Dual USB output (w/imbedded Micro USB) for Apple iPhone 5 4s 4 3Gs 3G, iPod Touch, iPad 2 3 4 / HTC sensation, XE, XL, One X S V, Thunderbolt, Inspire 4G , EVO 3D, EVO 4G,... and PowerGen PGMPP8400 8400mAh External Battery Pack High Capacity Power Bank Charger Dual USB output for Apple iPhone 5 4s 4 3Gs 3G, iPod Touch, iPad 1 2 3 4, The New iPad 3/ HTC sensation, XE, XL, One X S V, Thunderbolt, Inspire 4G , EVO 3D, EVO 4G, Desir... are great power charges. The only problem with them is that they are an additional item to carry around, bothering about the size of a pack of cigarettes. If you don't mind spending the money and only need a convenient carry-around back up, then the Energizer is the product to go with. If you want more power for extended periods of time where you might not have an electrical access immediately available, then look at the other chargers.

Purchased last night and when opened, it was not fully charged. Plugged in and charged in less than 2 hours. Had 4 bars. When I woke up this morning, I noticed that it was down to 2 bars even though I had the charger in the off position all night. This is why I am giving 4 stars instead of 5.

The actual feel and size is perfect. Not too bulky at all. Was deciding on this one and another product, but that product would have made the iphone way too big. Great choice.
