Will this pack itself fast recharge if I have a 2 or 3A AC charger? What is the fastest it will recharge safely?

Issue is in my region the unit does not ship with a charger. The device must have a current limit to prevent damage. Any suggestion what that limit is or what is the rating of the charger supplied in your region?

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 .

Yes, it seems to charge pretty fast. However, like I mentioned in the review it also seemed to drain faster if I used this charger.

Both are fast charge 2.1 and the unit is on my buy another list. Quality unit.

There is no set answer to this question. It all depends on your phone. If you have things like wi-fi, Bluetooth turned on or "Hey Siri" turned on, or lots of notifications such as Twitter/Facebook/sports etc. it takes a lot longer. If you have the phone turned off and charging it can charge very quickly. Especially if you use the two higher amp ports. if you are really looking for a quick charge, you should search for "quick charge" device chargers

I am looking at the unit CA-2421 and it says It DC 5V 2.1A. I also can it charges really fast.

The battery claims to have a 1amp output, however it doesn't seem to charge as fast as 1amp wall outlet. I believe this is because the phone is recognizing it as a USB charge, and not letting it charge at it's full speed. Some specific phones have aftermarket (aka, root, rom, and kernel) support for USB FastCharge support but it doesn't seem the most up-to-date (android 5.0) supports it yet, while older versions do.

It may be more than 2.1. My phone seems to charge pretty fast on it, it's an iPhone 6.

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.

Both the chargers are self regulating depending on the battery voltage so the 5amp charger will charge faster if the battery voltage is low. If you discharge the battery to a low level the 5amp charger is the best solution if you don't discharge the battery to a low voltage condition the two amp charger is fine. To cover all conditions the 5amp is best. Make sure your battery and connector are compatible. Hope this helps

Its just a normal charger, I work for batteries plus. you do not want anything faster, Lithium batteries have circuits to prevent rapid charging, because of the heat. Lithium is explosive, and even if you find a higher mA charger, the battery will disconnect itself from the heat.

The speed of charging depends on your cable. It doesn't come with 3.0 cable, but if you have one then you'd be able to.

Its a bit short so you may need to charge every 3-4hrs but it recharges fast

Yes, works great. It comes with a 2 amp USB charger. You can use the 2.5 that comes with your phone if you need a faster charge. I use the one that came with this for over night and have the 2.5 connected to the dock where I sit to charge the phone or battery quickly. The only time I really need the extra battery is on weekends when I am not driving and don't plug in between jobs.

No. You want to buy a 2 amp wall charger if you expect overnight recharging. If you try to recharge from a laptop or similar low-current device, it will take quite a long time. Chargers sold with tablets may well be 2 amps.

I have that Powerpack and the wall charger that came with it is: AC in is 125v @7A and output is 12v @ 3A.

Yes, as far a being capable, it will fast charge if your wall part is capable. (the part you plug this into the wall) Without a wall part being able to charge at 2 amps, (fast charge) it will only do normal charge (about 1 amp)

Good question. As a generic usb charger at 1 amp, this charger works fine. That said, not all micro usb cables/chargers 'talk' the same, usually due to shorting of pins 2-3, etc to indicate an AC (higher current) charger. Generally, if you use your original usb to micro usb charging cable, you should be fine. I'm not sure whether this charger is designed to short pins 2-3 (or similar) inside the charger itself. If not, it should still provide the usb standard 500ma, as if connected to a generic pc usb port.
