With a fully charged 20V Max battery, roughly how many times would I be able to charge my phone before I would need to charge the 20V battery again?

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.

It depends on which battery pack you plug into it. The easiest way to calculate the actual capability is to work with watt-hours instead of amp-hours. Take the amps and multiply by the volts of the pack.12v 1.5 AH pack = 18 watt-hours20v 4.0 AH pack = 80 watt-hoursAn iPhone 6 battery has 11 watt-hours. Therefore the large pack could charge it seven times from a FULLY discharged state.

I have a 3.0 amp battery it last me about 4 days of charging my phone when needed I used it a lot when traveling one thing to remember is to unhook it from battery when not in use it will drain battery faster I never counted how many times but I charged but my phone never died from a dead battery hope that helps

I can fully charge my iphone 5 three times with a 12v battery. I'm sure the 1.5 amp hour 20v will do the same or more. The charge rate is very fast especially in airplane mode.

With a samsung note 2, about empty to fully charged, 4 or 5 times with the 4Ah battery but this takes hours due to the 1.5A max draw. Great for use without electric for days

During a power outage last winter I charged my I phone5 and my fiances samsung galaxy at the same time three times and still had battery power left.

It depends on the device you're charging and how drained it is. However, for standard reference, we generally get 3 charges out of it with an iPhone 5S when it's down to about 20%.

I have a few of these chargers and many of these batteries. If your charging two at the same time that are almost drained you can expect a full charge in about 3 hours.......Hope this helped.

If this is about the portable charger, ( amazon send me an email ) I have fully charged it and kept it in my car for two weeks before using it to recharge my samsung phone and it not only fully charged it once, but I was able to fully recharge my phone a second time the next day from the same unit. The first time I had neglected to recharge my phone and the battery gave out. The 2nd time from a very low state to full charge in about an hour.

On my LG G2 with a 3000mAh battery, it will fully charge 1 and a half times. I forgot to fully plug in my phone one night and it was totally dead. I fully charged it, ran it for a full day (very bad reception in my building which drains the battery faster than normal use) and charged on the way home . On the second charge, the phone went from 40% to 95% before I unplugged it. The Anker was not fully discharged but only had one light left on it's indicator...if this helps at all.

Theoretically you can. But it will almost canceled out. What I mean is that it will slow down the charging of the unit itself almost to zero. Even without a phone attached, it will take the better part of two days to fully charge the unit. However, from my perspective that completely acceptable because it holds a full charge for a long time. At least a couple of weeks. And I am able to charge my Samsung Galaxy Note 2 at least 5 or 6 times before exausting the charger's power. But it is not ideally suited to charging a phone and re-charging itself at the same time. If you want to use it daily - or even every few days - you need to re-charge it before it runs out of power. Because re-charging when it's completely dead will take a long time. However, I can't say enough good things about it. If you're going - let's say - on a camping trip where you will have receptions, it's ideal. It will re-charge your phone a number of times. And if you take along a solar charger, you'll be in Fat City. If you have a wall plug available, why wouldn't you simply charge the phone in one plug and the charger in another?

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.

The battery will only recharge your phone approximately 60%. If you plug it in to a power source pretty split-second you will be able to charge your phone 100%

It depends upon what you're charging the more amperage to charge the last life the battery has..

It can charge up to 4 batteries at a rate of 6 amps each. A 20 amp could do the job if you are not charging 4 packs at full capacity at once. A 30 amp power supply is a safe place if you are going to charge multiple batteries at once. Here's a good 20 AMP supply. Racer's Edge 20 Amp, 13.5V DC Dual Output RC Power Supply with USB

to my experience i have charged my galaxy s4 3 times, i dont know if that helps, i think it is more like 20,000 Mah, either way i bought it for 20 bucks still a great backup battery

To charge fully, the same as your phone, maybe 3 hours max... depends on how much you use too.

I have a Samsung phone that I use it on. I have charged my phone 2 times with the three batteries that came with the charger.

I see this as 2 questions : 1) how many times can you charge before having to recharge the remote charger - well that is purely a matter of from which state you charge from - I myself has charged more than 10 times before charging the remote charger again, however if the phone is totally down each time you charge it's another matter - then maybe two to three times before charging the remote charger again. 2) When is the battery totally dead and you have to buy a new charger - this is a matter of where you contain the charger on a daily basis (a cool place is better than directly in the sun) and again a matter of from which state you charge from, so it is in fact impossible to say,however, I have had my own for a year now, and it is still functioning. When this is said, then it is not necessary to buy a new charger if you use one with a replaceable battery as for example our stainless steel charger, which also have a larger capacity than the one in question - try to look after ASIN B00I01P196 in the amazon store.

Yes you can. You should charge it for 10-14 hours with first charge. Then you need to completely drain and fully charge your battery at least 6 times to get the full capability out of your battery...

as far as I know , you can.. The more mAh increases the time the phone will last before needing recharged... Voltage must be the same

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.
