With fresh NiMH batteries in the charger, how many times will it charge an iPhone 5?

The energy stored in 4x 1.2V 2300mAh NiMH batteries is 4*1.2*2.3=11Wh.The iPhone5 has a 3.7V 1440mAh Li-ion battery. Total energy=5.3Wh. But due to conversion loss (25-30%), you can only recharge the iPhone5 by about 1.5 times.

It will charge 5 iPods, iPads or iPhones at a time. You will need the adapter for iPhone 5's.

To tell the truth, it depends upon the charger that you are using. If you are using the one that came with battery and simply slides onto the battery, it has no way of knowing when the battery is charged and will keep pumping current into the batter, unless you disconnect it, and will eventually "fry" the battery. Doesn't matter if it is NiCad or NiMh. Do yourself a favor and buy the "Black & Decker FSMVC 9.6-Volt to 18-Volt Slide Style Battery Charger". It regulates the charge and won't fry the battery. I've been using two of them for over a year and have not fried NiMh batteries, so far!

Yes, it charges it fully, don't know how many times though. But I like my Mophie.

The primary problem is that NiMH batteries do not like to be force-fed/overcharged, and that is exactly what NiCd "low-end" chargers do: they are basically constant-current "trickle" chargers (low current, takes many hours to charge, then keep feeding this same charging current even after the NiCd is fully charged). NiCd batteries just shrug off this excess charging current, but it will eventually "cook" your NiMHs. That said, NiMH will pack much more punch into given size...so if you don't leave it on constant charge (drain it, charge it overnight, then unplug it once "properly" charged) it should work quite well. Of course if you ditch the crappy little wallwart "charger" and hook it up to a proper NiMH charger, it'll work Great!

It takes quite a while to charge it from completely drained to a full charge. It took me about 8 hours the first time. I have charged it the last few times with one light still showing and it took about 5 hours. However, it gave me over 10 hours of additional use on my iPad Air. I have totally charged my iPhone 5 twice on one charge of the battery. I have had one that I did not use for almost a month and it still had three out of four lights showing and was able to completely charge my iPhone. I believe the information said the battery would hold a charge for 60 days, but I have not personally left the battery unused for that long.

I've gotten four charges out of my iPhone 5c before having to charge the battery pack.

there is no way to charge 2 NiMH batteries at once? adapter board such as the one for lipo? is there a dual charger designed to charge 2 NiMH batteries at once?

I do not know about those particular devices but I was able to recharge my iPhone about three full charges and a half charge before depleted. One full charge on an iPad gen 3. And about 2 charges on a iPad mini

will charge about 1 iphone full HP... (when iphone is idling without using, around 80% if using simultaneously)

I don't know how many times, but I got the 75 hour battery and it will literally last days. I would expect it to power up an iPhone many times.

No. This is for charging Lithium Ion batteries which are 3.75 Volts. your niMH batteries are 1.25 Volts.

It should. It will charge an iphone5 to full at least 4 times on a single charge

Edward Shimkus' answer is right on target. I have yet to even charge the supplied Sony Ni-MH batteries included with the charger. However, I have recharged a number of times some old Duracell (2650mAh-not high capacity version) Ni-MH batteries with excellent results, including using the "refresh" function provided by the device. I'm very satisfied with this device and feel it is well worth the price.

Every charger for NiCd/NiMH batteries will charge each and every NiCd/NiMH battery as long as it will physically fit there or/and voltage is right (1.2V). Rapid chargers however reduce batteries lifetime. AA batteries should be charged with 200mA. It takes 12 or even more hours but batteries will last for years.

Any charger as far as I know that says it charges NiMH Batteries. I have used about 4 different charges for them and other rechargeable batteries and if the specified NiMH all was good! Anybody that does not use rechargeable batteries now a days is crazy! One thing to look at is the mah rating for the battery, for triple A batteries I use 1000mah or above and double A batteries about 2600mah or higher.

It's a cell not a circuit. I use only Li-ion and Li-Polymer 9 volts on about 20 projects that continue to run to discharge with no problems; a smart charger exclusively for these batteries has the circuit that has yet to fail to charge any of these 'over-discharged' batteries. Most electronics stop working at a certain voltage long before the battery is totally discharged. Still, even with current-hungry circuits, none of the 40+ various lithium 9 volts I use for the last year and a half have failed with constant charge/discharge.Can't say the same for NiMH.
