Have been using this system since 2013. Traveled to Alaska and back to Florida. Just plug your base into the cigarette liter slot and go.

Hopefully I will be able to find a fresher battery somewhere.  As for the phone...it's not easy...I'm just learning.  Not the phone's fault.

Pretty good device to keep you hands-free, but the battery seems to run low more often than I want otherwise easy to use and the speaker is pretty good

It is a mission the save the data to the memory.
Also when the battery is weak you can permanently lose your data.

Make sure you don't blow your batteries up in your hand. Re wrap them when they tear.

I had a dying phone.  Replacing the battery did the trick.  The phone indicator said it did not hold a charge.  That's how I knew the battery was dying.

Look at it daily.  Worth buying and hanging up somewhere to keep you grounded.

Install new life proof but we also got to spend the money and text your phone as much as it can possibly be protected for an iPhone 6 plus

works great and is better than battery loaded. You can hear it when you close to it thats assures you that is working. Piotr

Read this first, and hear a message from these ladies and gentlemen. They speak to you.  It's your choice to hear them or not.

Like your mobile phone, save some money, and buy it a new battery. Your phone's charge will last just like it was new.

Lets you know if the battery needs replacing or what it was in needs repair or replacing. This keeps you from disposing of good batteries.

This is funny to install and feels a little crude, but it gets the job done, data-wise.

Be sure to get back-up batteries so you don't disappoint yourself when the current one runs out.

And it won't hurt you either, but it will keep your phone/tablet going till you can find somewhere to plug your charger. This thing is GREAT! For $26 you can't beat the 10amp/hours* capacity that will keep your device topped off and ready. Gonna have to buy another though, a family member has "borrowed" the first one.
Cons:(minor) You have to turn in on, just pluggin into the USB doesn't activate the charger. I wish it had some kind of indicator that the solar is charging the battery. (Now I'm just whining)

*(compared to my Note 4 battery which has 3.2amp/hours)

directions are a bit much, plus they want you to leave your phone off for 4 hours if you can.

If you find yourself on the road a lot, away from reliable sources of power, a backup battery like this might be nice to have. It features a couple of USB ports that you can plug mobile devices into for an extra bit of power. It works just fine, recharges in just a few hours, and keeps your devices going when you're on the run. I have no complaints about it.

Going out? Traveling? Oh no you need some juice. Your phone's battery died. Your friend's battery died. My friend...this will save your life. This will save your friend's life. What you get with this is 2 USB ports. One you can share with a friend and one you can use yourself. The amount of power isn't too much. It's rated 4000mAh which isn't a lot but not too little either. You'd be able to charge your phone about 1-3 times. This thing has no power button. Instead when you plug a USB device to one of the ports, the lights flash on letting you know the power went on. Sometimes you forget to turn the power off on power banks...but with this it will be off as long as a device isn't connected to one of the ports. That's just smart. This also came with a micro USB cable in which you charge the power bank by plugging in the micro USB end to micro USB port of power bank and the USB end to a USB power source...or you can use it for your android device. It's a nice and small and portable cable. This has 4 LED lights in the front. When charging, the charging level of 0-25% displays 4 flickering lights. 25-50% displays 1 LED light and 3 flickering lights. 50-75% displays 2 LED lights and 2 flickering lights. 75-95% displays 3 LED lights and 1 flickering light. 4 LED lights are displayed when the charge is complete. Overall, I would recommend this product as it provides enough juice for you to get your phone charging and it's also nice when power banks offer an additional port to share with a friend or w/e.

Pros:
 - Black matte finish helps it from getting fingerprints/scratches.
 - Portable. Thin and flat and not too large. Fits in most pockets nicely and easily.
 - Enough juice for you to get by the day.
 - Share a port with a friend. This thing comes with 2 USB ports.
 - Smart Power On/Off Feature. Plug a device on, power bank turns on. Unplug the device, the power bank turns off.
 - LED lights letting you know charging status, etc.
