Customer Questions & Answers

I should have demanded for a refund.
Ike Okoye
The instructions say to take the phone out of the case to charge it in the sun; it heats up which can damage the phone's battery.
J.C.
It does recharge the phone via the built in battery, and charges that via the panel or mini usb.

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.

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.

Color Name: Black Vine Customer Review of Free Product ( 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).

Worked ONCE then QUIT. Not worth the frustration of returning it. Really really sad because I'm a huge greenie and supporter of renewable energy and better technology. I couldn't be more disappointed. The instructions were terrible, the device difficult to use, to take on and off of the phone, and to connect.

Color Name: Black Vine Customer Review of Free Product ( What's this? )
I travel to remote areas about once a year and was looking for something to charge my iPhone on--not to make calls or use the Internet which are usually unavailable in these locations anyhow, but to use the phone to play games or use some of the other non-Internet needing applications. And, of course, to keep the phone charge so when I do get to areas where there is a 3G or Internet connection, the phone can be used.

If you've used solar chargers you know that they vary in the length it takes to charge something and in the strength of the power. With this one you can charge the unit via the USB cable or you can leave the unit itself (without the phone in it) out in the sun.

The unit does give you extra battery life for your iPhone, but if you are relying solely on solar to charge it, you'll need 12-18 hours in full sun to get the unit up to maximum speed. If you are on a tour (like I usually am), sometimes you don't stay that long in one place and if you put it in on a hotel windowsill then as you know the sun rises in the east and then sets in the west so you don't get a full day of sun charging. You can purchase devices that allow you to plug the USB cable into them and then you can plug them into adapter which of course allows you to fully charge the unit and gives you more battery power for your iPhone.

This isn't a bad little device, but as with many solar units, it does take awhile to charge with the sun. And of course if you travel to a place, say Iceland, where in the winter it is dark 23 hours of the day for some weeks, well, this little item then will only work for you when charged via the cable. I had no problems with it charging either via the USB port or using solar power to charge it unlike some reviewers.
