What's the difference between 1A out charge and 2A out charge? If it is full charged, how many times it can be used to charge empty battery cell phone

2A outlet is used for more power demanding devices, e.g. iPad, Samsung Note, or Samsung Galaxy S4 etc. For example, if you want to charge iPad, please use 2A. If you want to charge your iPhone, 1A is good enough.13000mAh is a big battery. It can charge smart devices many times. For iPhone, this battery pack could charge around 7 times. For Samsung S 4/5, it could charge around 4 times. For iPad Air, it could charge from empty to full and then charge an iPhone from 20% to full. This battery pack uses Samsung battery cells. The life cycle is also much longer than normal battery pack. It supports 1000 cycles of charge/discharge. 2A outlet is used for more power demanding devices, e.g. iPad, Samsung Note, or Samsung Galaxy S4 etc. For example, if you want to charge iPad, please use 2A.

The 2A is generally for tablets (iPad or Nexus7), as the 1A is for most phones. Depending on the size of your phone battery depends on how many times it will charge it. This pack will charge my Nexus7 (2013 model) about 2.75 times, it will charge my iPhone 4S about 5 times. Another option... I use one of these as a UPS unit for my Raspberry pi VOiP server.

My guess is that it would only charge the phone once. If you're looking for something for multiple recharges I also have Anker® Astro E5 15000mAh External Battery Pack 2-Port 3A Output Portable Charger Power Bank for USB Devices (Black)This would charge your phone 5 to 6 times. I love mine and use it all the time.

Battery should be described as 2ah (amp hour) & 4 ah. The 4ah battery will last about twice as long between charges as the 2ah battery. Two 2ah batteries will allow you to keep working while recharging the other battery. However I have one 4ah battery for my pole saw that lasts as long as I do. There are other pages on Amazon that correctly describe the battery as 2ah or 4ah. You may want to order from a vendor that more accurately describes his product (I looked and didn't find a better description that was compatible with the same charger as the one you are considering). Also confirm that the battery that you order is compatible with the charger. I see that there is ample opportunity to get a mismatch.Good luck.

I got about 3 full charge on my phone and never really needed to go for the 4th charge and I have notice that the battery had leftover charge BUT!! If you leve the attachment (DCB090) on the battery it will drain the battery even if your not using it and that sucks. Now if you're asking yourself what is the difference between buying this and buying a juice pack battery or any other battery packs... The difference would be that any other battery packs take hours!!!!! to charge and a Dewalt drill battery takes about 5 to 10 minutes to fully charge.

As there are numerous battery configurations, the X1 does require you to input the type of a battery you are charging/ discharging. It has all the battery types stores so you just need to select how many cells (1S, 2S, 3S etc). Once you've done that, it will detect how much is still in the battery and deliver only the amount of charge needed to max out the battery. (You can adjust the threshold and override those also). So for 3S battery at 2700 mAH at half full it will deliver only 1350 mAH more. Unless you tell it to deliver more (not advisable to do this over a few percent).

I advise u not to charge it with a different charger b'couse it may cause defect on it . The battery can support a certain A or volts but it was designed to measure when it's full charged or empty , what i'm trying to say it's u can short the batery life if u use the wrong charger .

My understanding is that 2A is the maximum. If you use one usb port, that port will get the 2A. If you use both the current will be distributed. 4A seems too much to take from your car battery anyway.

Not quite sure. You'll have to experiment for yourself. Since I don't use it regularly, I just always give it a full charge whenever I need to take it out when using it occassionally.

Once both are charged, it runs off the phones battery power. When your phone gets low, you turn on the battery case and it will charge your phone back to 100 %. Then the battery case turns itself off. I can charge my phone when it's gets down to 2 % and use the case 2 full times before I have to charge the case again.

This PortaPow unit charges in pairs. That means you can charge either 2 or 4 cells at a time. It does NOT charge any faster when charging 2 cells.

If you don't fully charge the battery the first time, is can develop a memory and you will never get the "full use" of it. ALWAYS charge anything with a rechargeable battery at least 12-24 hours before use (cell phones, cordless phones, GPS, etc) it will just ensure you don't need a new battery for years.

Get this. You'll love it. I can re-charge one cellphone at least five times on the charge this thing stores. You can also charge two items at a time. It has LED lights that tell you how much power is left in the charger. It's great for camping trips. Holds the charge for a LONG, LONG time. (Like weeks.) If you let it get totally discharged you will know it because all the LEDs will be out. It's never happened to me because when it gets down to one or two LEDs left, I recharge the charger. This is a great item. Get it! You will ♥ love ♥ it! No drop in performance yet and I've used it a LOT! Get this. You'll love it.

my samsung s2 generally gets about 5 full charges from one fully charged battery. heads up - if you are looking for a battery that will fit in your pocket for going out around town, you may want a smaller type battery.

I have a La-Crosse BC-1000 which I have used to it's fullest potential. It's a very intelligent and powerful charger allowing you to charge at different amperages (higher for quicker re-charge and lower for a better recharge) as well as being able to completely de-charge to eliminate battery memory issues that don't allow a full charge. You can charge AA's and AAA's at the same time and each of the 4 positions is independent of the other. In other words, when one cell is charged, it will discontinue charging the fully charged one and continue charging with the rest and so on. There a little spendy, but to get the most out of your batteries for years of use, it's a great charger. I have a La-Crosse BC-1000 which I have used to it's fullest potential.

I can usually get about 3 charges out of it. I tend to use my phone (for twitter or whatever) at the same time it's trying to charge it, but I can usually do that 2-3 times before the Pebble is drained. I love my Pebble! Wouldn't travel without it, as my phone tends to drain quickly when I'm in roaming territory.

I didn't try to charge two cellphones at one time. The 2.1A port is usually designed for tablets since most smart phones have charging current of 1A. The 2.1A port could charge a cellphone but it might cause some damage on the charging IC or/and the battery of the phone.

I've used mine a couple of times now. It will charge my Android phone four times before I need to recharge battery. It will charge any device that has a usb cord. You can charge the battery through your computer or by plugging it into the wall with any plug that has a usb port.
