If a Lithiumion battery is a must? (included) AND ALSO &#x3010;Built-in&#x3011;dual USB charging ports for directly plugging in iPhone, iPad and other USB compatible mobile devices My questions are: &#x3010;1&#x3011;If there is a USB port in the charger?

It has 2 usb ports that can directly charge your usb devices Phones Tablets etc. I comes with the litium ion battery which can be charged frm the usb port on the panel and used to store power so you can still charge devices at night or in low light conditions

Although I haven't tried this, I believe so. I just plug mine into my charge block for my iPhone or other block that has a USB port. There are also Software upgrades for the device that I know you need to connect to your computer in order to upgrade the device for new features as they come out.

I copied this from the comment in the review above from 880 User: "This battery can definitely be charged and is meant for convenience. It does not come with an adapter so perhaps that's where your confusion is? At any rate, not sure what you're thinking but just use your iPhone wall charger and provided USB cable to charge it up, then carry it with you and use your iPhone charge cable plugged into this guy to charge your iPhone - over and over. The whole premise is based on extending your iPhone battery for convenience (and emergency) not just a one time use".

I forgot to comment on the doc. You can't without an adapter. I have a thin incase and I have to take the bottom off to charge it. You will either need an adapter (which I haven't found for the lightning connector?) or use the secondary USB charged on the back. Kind of a pain.

Yea. It has a USB charging function I know. But I have read in some reviews that the charger doesn't work with some devices or something. So just wanted to confirm from somebody who has already tried or is using with an iPhone or iPad.

Not recommended. Don't remember if there's a connector for iPhones. AA's are not strong enough to fully charge iPhones. Recommend lithium chargers instead with at least 2500 mah.

The cable that comes with it is to charge the battery. You could use the cable that came with your iPhone and iPad to connect it for charging.

Use the 'USB to Iphone' cord you already have to charge your phone. Fully charge the portable battery then insert the USB end into the portable battery and the other end to your phone. Wallah...

If you have something that has a usb charger, you could use the other port to charge that device (depending upon what that device is). I plugged in a little rechargeable travel charger into it, and it started charging, but my iPhone didn't charge. It also doesn't connect your device to the computer. So it doesn't appear all that useful, but I think it depends on what you're plugging into it. Any kind of drive I don't think is going to connect, but some chargers would work.

You can use an external battery such as the type to charge and ipad (has to be 2 amp). I ran mine 10 hours on a 5600Mah. A 10000Mah should last all day for sure. Of course recharging them takes a while so this option would probably be best for occasional use.

Yes...the built in cable you see in the photo is micro-USB which is for Android (very convenient since you don't have to carry a cable with you). For iPhone, you would plug in your separate iPhone charging cable into USB port on the top of the external battery. I have charged both types of devices and it works like a champ.

No . No separate charger is needed . You may use the USB slots . There's two .

No, you don't have to have one. It comes with a short USB cable. All you need is a wall charger that you connect a USB cable into. I already had one that came with my phone so I didn't have to purchase one. All 3 of us in our family have this extra battery and love it! I don't know how we ever made it on long trips without it!!

The charger has two usb ports, a usb2 and a usb. I see no reason you should not be able to charge two at once though I have an iPhone 4. That charges quite quickly.

Keep in mind that this is just a cord and not a power source. I don't own an iPad but if it's like other Apple products, it's hard to get 100% charge from a USB source; you need to use a wall outlet. BTW, I've read that 40-80% charge is best for lithium batteries, w/ a complete drain once a month or so to obtain optimum life; so a 100%charge is not so great.

Personally I bought the "New Trent PowerPak Ultra 14000mAh Portable Dual USB Port External Battery Charger/Power Pack for Smartphones, Tablets and more" it's the best among all others I tried before capacity keeps you running quite some time... works very well for iPads too and you can charge an iPhone at least 7 times with a full battery.

There is no built-in battery recharging function from USB, and it's likely the unit gets no operational power from USB either. So this answer is pretty surely no. They say to use an alkaline battery, but I found it works fine with an AAA rechargeable battery (even with its lower cell voltage). However, you have to recharge that battery on your own separate charger.
