3.0 out of 5 stars Cool Case but some things to consider... October 9, 2011

By Chris Ace

Color Name:Black|Amazon Verified Purchase

Ownership: 3 days

The GOOD
-Feels very solid
-Really does increase your battery life (provides an extra 1800mAh)
-Solar Charge Indicator
-Battery Charge level indicator
-You can charge the case without the phone being in it
-You can charge the case through USB or Solar even if the case switch is OFF
-Buttons/switches are still easily accessible
-Curved backing makes it feel great in your hands

The BAD
- It's huge
-The clear plastic piece protecting the solar panels is made from cheap plastic. (it has an ugly rainbow distortion effect in certain angles)
-If you have some sort of screen protector, it will get lifted (and bubble) from the bottom when you snap in the case.
-The iPhone is 9.3mm thick, this case makes it 21mm thick. So a little more than double
-Not designed to protect your iPhone, so don't drop it
-Can no longer input apple dock connector unless you remove the iPhone

I wouldn't buy this using the solar panel as the source of its energy. You should buy with the intent that this is a case with a built in battery and the solar panels as a plus. Consider this: it will take approximately 10-14 hours to fully charge the case in the sun. The solar panels are more of a last resort thing (like your car broke down in the desert and you have no energy)

The more ideal situation I've found this useful is if I'm going out to Disneyland, I leave this case in my car's dash (to store energy) while I enjoy the park. I get back to my car to a case that's got some free energy.

**1 Month Update**
battery has depreciated. It now charges the phone about 75% as compared to new. It is extremely bulky and sometimes difficult to take off. Now I use it more as a last resort battery in my glove compartment.

5.0 out of 5 stars Very Handy Battery Case September 22, 2011

By KZ

Color Name:Black

This is a pretty sweet little battery case. I used it over the weekend and it came in pretty handy while I was out at an outdoor bar. I had it out on the table next to me for about an hour and a half and was able to get about 30min of extra talk time. This was about 7-8% charge on my iPhone. The unit has a standby switch so I was able to actually store the charge from the sun and use it later to charge my iPhone.

The unit is pretty intuitive, snapping in the iPhone and then pushing the connector up and into the phone and you're ready to go. The only thing is that it was a little tough to remove, but if you open it like you're opening a book, the iPhone pops right out. It takes a few tries to get used to, but otherwise simple. The unit is well made and feels solid. It does add a little thickness, but with the added solar panel, it's well worth it. It felt pretty much the same as my old Mophie battery case when it was in my pocket.

Lastly, in addition to the fuel gauge, showing the battery level, I really liked that this unit had an LED that would turn on when there was enough sunlight hitting the panel to charge.

3.0 out of 5 stars Good if you work outdoors November 17, 2011

By H. Lee VINE™ VOICE

Color Name:Black|Amazon Vine™ Review (What's this?)

I have to admit that I had a bit of a misperception regarding this product. I thought that the solar panels would actually charge my iPhone battery, but it is really an auxiliary battery that gets recharged through sunlight which then charges your iPhone battery.

The good:
- If you spend some time outdoors, this is a great device in that you don't have to worry about finding an outlet to recharge your phone. The solar units charge even when it is overcast.
- Set-up is simple and intuitive. You slide open the case, snap your phone in, and slide it closed.
- The auxiliary battery can also be charged through an outlet.
- Your iphone doesn't have to be in the unit in order to be charged
- extends the run-time of your iphone significantly

The ugly:
- the extra weight added to your phone, will obliterate the entire slim, cool effect of your iphone as well as giving you a flashback to the 90's when phones felt like bricks
- in order to charge the unit while it is in the case, you have to place it face down and there is a very minimal buffer. I haven't scratched the face of my phone yet, but it still makes me feel uncomfortable
- no way to charge or sync the iPhone itself through the port. The solar charger uses this port itself. Next to my bedstand, I have 2 chargers - one for the solar battery and one for the iPhone itself
- the solar battery recharges through a microUSB. I still cannot fathom why they would design something that would require an entirely different charger
- as the solar battery charge winds down, it goes through this psychotic power flux which ends up turning the "charge mode" screen on in the iPhone on and off (the screen that shows the battery picture with power level in green). You will be driven insane by hearing the "charging" chime every 20 secs that can only be alleviate by decoupling the case from the iphone.
- the manufacturer recommends that you NOT charge the solar battery with the iPhone in it - ?!?!? Seriously? I think this is a more of a legal disclaimer since it does heat up after sunbathing a bit.
- does not charge indoors through artificial lighting, unlike most calculators.
- you will get ridiculed by your coworkers and be labelled as a cellphonosauras for having such a bulky phone. Ironic thing is that you have the coolest thing on the market. It's like driving a Ferrari with a Domino's pizza delivery sign on top.

Overall, if you find yourself difficulty getting access to an outlet charger on a daily basis, this unit should come in handy in that you can harness green energy. But I rarely use my phone enough to deplete the charge within a day and usually do fine by just recharging at night. If you are the type to forget doing this then the solar charging aspect can come in handy. You can leave the case in your car - then you run into the paradox of having no case for your phone.
