Can you have the phone in it, but save the extra charge until you need it, or does it automatically charge and drain itself?

The external charger has an on/off switch, i.e., you can carry the phone, with the charger attached, and you decide when to use the charge.

It has a on/off button on the back so you can make it start or stop charging whenever you want to.

I go ahead and charge it. I think you have to charge it now and then even if you don't use it.

If your talking about the case it self yes it charges without the phone in it. You can charge both phone and case by them self they each come with their own chargers. Hope this helps!�

Yes. It is designed to first charge the phone if it is not fully charged, and then it will maintain the phone's charge while it charges its own battery.

If the phone is in the case when you plug it into charge, it will charge the phone first until ful, then charge the battery case. You can plug in the case without the phone to charge it by itself.

No. You have to turn it on with a small button in the back. Usually when the phone gets down to 35% or a little lower, turn the battery on. You can leave it on all day (charging) but it does not last as long. It works better to use it as you would a charger. When you need a charge turn it on, when it is charged turn it off.

You could leave the unit plugged in until you need it but it's not necessary. It holds a charge for a very long time. You won't be disappointed. I purchased this for my husband three years ago for Christmas. He still says this is his favorite present, EVER!

Yes and yes. I leave mine on my phone as an added layer of protection for the phone and use the charger as needed. If both are down, the phone will charge first, then the charger, but you won't even see it if you plug it in at night. Just a few hours and both are charged and ready to go.

You can charge the phone with the case on it but it will not charge the case at the same time. You have to charge the case without the phone in order for the case to charge the phone when it's not plugged in.

I would recommend to install it into the phone and drain the battery prior to fully charging it. Do this 2-3 times. After, you can def charge the battery anytime. Just like with any rechargeable batteries, its always good to drain the battery before charging ones in a while.

The phone does not have to be in the base. You can put the phone anywhere you want in the house or even out in the yard or garage. However, the base must be plugged into an outlet for the phone to work (it's like a transmitter or whatever the proper term is). Also, the base is the re-charger when the battery gets low on the phone. Like a cell phone, the more you use the phone the sooner it loses it's charge. It does seem to hold a charge for quite awhile. I usually put my phone back on the base when not in use, just out of habit. Also, you have to have the main unit for the auxiliary phones to work.

You charge the battery just like you charge your phone. And yes you can use your phone while it is charging.

I haven't found that it does, although I don't tend to use the charger to also charge the phone at the same time, as one can. Instead, I simply use the charger to charge an extra battery while I'm using the phone, and carry it around with me. If I have a particularly heavy day, I'll just swap out the battery from the phone and substitute the fully charged battery from the charger, then when I get home, use the charger to recharge the depleted battery.

It charges the phone pretty fast, but takes awhile when you are actually recharging the battery itself. Without a purse or large pockets it would be cumbersome to hold the battery while using the phone. For me I just have the battery in my purse and hold onto the phone when I need to use it mid-charge.

No. As soon as you plug in the charger, your phone/stuff will do an emergency shutdown. All that happens to my stuff atleast.

I believe it charges while in use, but I rarely use it without having it plugged in.

It's plugged into the power source, so my answer is yes. It's using power also so I don't know if you would notice it charging, but I can say I've used it when I had no power on my battery and it worked perfectly. I never noticed a drain on it either. It's like using the tablet while charging it. I hope this helps! :-)
