Sorry, we didn't have a test result for this.
Mobile power charging current is 1A. So if 5000ma Mobile Power with 1A charger, generally 5-8 hours to full, stable voltage and frequency standards.
How many times it can charge for my phone?
A: depends on the actual situation, subject 1000ma battery, you can charge 3-4 times.
Follow-up: Why only charge more than three times? Not 5000ma? Is not the manufacturers cut corners?
answer: The manufacturers uses battery 3.7V voltage 5000mah capacity; boost to the 5V output. Here have efficient 3.7V 5000mah equal to 5V, 3700mah, then get rid of lines and CPU operating loss of actual output 3500mah. Therefore, manufacturers nominal capacity is the capacity of the battery used, rather than the actual output of the capacity.
How much is the warranty on the product. Also how many cycles the battery can be charged for?
Hi Rep. What type of battery is this? (Lithium Ion, Lithium Polymer, Nickel Cadmium, etc.)
Forget all that
"This iPhone Charger charger has strong power and high capacity that you will like it"
SOLD!!!!
Yeah screw specifications, it's all about the marketing!
hi rep, can you please confrim this battery can charge an ipad, i bought some external batteries before and non of them could charge ipad….only mobile or mp3 player
Output: DC 5.0V 1A.
For the iPad you need 10v, so it will either not charge or charge extremely very slowly!
For the iPad you need 10v
huh ??? i thought they were all 5v, otherwise, how does it charge via USB ???
The 1A output current though means you can only charge 1 iPad at a time, iPhones only need half that so you could do 2…
This charger is not suitable for iPad.
iPad needs about 10W = DC 5V 2.1A, while this charger provides only 1A. Hence this charger suits only for iPhone or iPod, but not iPad.
1A should charge it, but more slowly… like using a normal USB on a computer…
i don't think i'd be getting this device for an iPad though…
My iPads are VERY finnicky about what they allow to charge them
this is bs.
Citation by a someone with more knowledge as me… but I think you need to use the good ol' water analogy when considering one of these chargers (ignoring the laws of gravity, electrical loss etc. of course).
Consider your phone/tablet as a bucket and consider one of these chargers as another bucket joined together at the lowest possible point and with both buckets on the same level. If one bucket is empty and the other is full and you connect them together this way then the water will fill the empty bucket only to the point where the water level equalises. Easy enough to understand, right?
So, if you have a phone with say 2500mAh battery that's flat and you connect a 4000mAh charger pack to it then your phone will only charge to around the 2000mAh level and will never fully charge. Expecting it to fully charge would be like expecting the empty bucket to defy gravity & magically fill to the brim with water from the other bucket and that wouldn't happen without a pump.
So, the question I need clarified by someone out there who knows more about electrical stuff is if I have a 2500mAh battery in my phone wouldn't I need at least a 5000mAh battery pack to charge it once? This also means that assuming an iPad battery is at least 11,000mAh battery then a battery pack of over 22,000mAh is required to charge it once to 100% right?
Hmmm, good to know - never thought about it that way…
you're confusing voltage with current… as long as there is enough voltage difference, a current will flow… (that is the 'slope' the water is flowing between your 2 buckets, one is higher than the other)
Ahhh, nice one JV… but surely if the battery in the pack is a similar voltage to the battery in the phone (lets say around the 3.5-4V mark) then the voltage would drop off the lower the battery pack got while charging the phone which would also result in a less than full charge, yeah?
I can understand a full charge with say a 12V car/motorbike battery through a 5V regulator as the 12V battery has both higher voltage AND current stored but it's always baffled me with these smaller packs that have very similar batteries in them to the phones in the end anyway. It's not as though you can 'pump' electricity into the device to charge it, right?
Sorry for all the questions but I think this may clear this up for many others and possible even save people from buying something that may not do what they expect.
yeah?
good point, i hadn't thought about that…
This is like the curiosity show :P
I own a similar rated pack to this and can charge smaller stuff like tiny MP3 players to 100% no probs but when used on larger stuff like phones & tablets it never seems to get there. In saying all this though it's still a great idea to have in an Emergency as you'll at least get half a charge from it which could get you out of a sticky situation so not all bad… just don't expect these to ever charge a phone or tab to 100% OK.
If anyone else can shed some light on the absolute facts of DC-DC charging please please please enlighten us all. It's 'only Physics' I know but there's a reason I failed it back in High School ;)
You are assuming that one battery is directly connected to the other and that each battery is the same which is not the case with smart devices. This unit outputs 5v (has an internal 5v regulator likely regulated from a higher voltage) and the battery in your modern smart devices is generally 3.7v. Your phone, tablet etc has charge circuitry to control the charge switching, voltage to the battery etc.
Also, a mAh rating does not specify a voltage, only a capacity. A more accurate battery rating is actually Watt-hrs. Eg, a 2000mAh 1.2v battery has less than half the capacity of a 2000mAh 3.7v battery
For 11.98 i wont expect this to do all it claims to do.
However in many years of buying cheap stuff online there is only one thing to remember - buy cheap, you get what you pay for.
just curious, what happens when you connect the same cable to the input and output?
Nothing, the internal circuitry wont let you… well, it doesn't on my equally cheap & cheerful unit anyway. You have to turn it 'on' before it lets current pass out the output which in turn disables the input. If you turn it 'off' then that obviously turns the output off.
Your queston takes me back to when I connected a torch bulb (remember them?) and a small solar cell to a rechargable battery and couldn't understand why it wouldn't just keep on shining forever :P
I agree with you :)))))
These cheapy battery packs rarely produce the advertised capacity. My guess is you would be luck to get half that capcity.
For $12 can't complain too much though. I have a Belkin which cost me about $60 from memory, 4000mah.
Can't believe I hesitated on that Belkin deal for $24. I'm very much regretting it, now.
Don't know if any of you use WOT (Firefox trustworthiness ad-on) but it poops a brick with this site.
Multiple warnings.

So, just to be clear, is this an iPhone Charger, or an iPhone Charger charger?
Any deals on iPhone Charger charger chargers?
:))) seems like a tongue twister.
But we are so sorry, we didn't have this
sigh, I was referring to your description.
And you should just refer to it as an external power pack - alternating between iDevice Charger gives the impression that, like other cheap generic stuff from Ebay, this will be only for said iDevices.
Show me the full circuit diagram of this unit, then we can see what is actually in it.
Thank you
I will try to contact them to see if we have a circuit diagram :)))
Magic… thank you, then we will all know what the story is.
cheers
We are so sorry. but they can't find one for us.
They only provide this one to show what's inside.
I have uploaded one picture. can you see?
http://i49.tinypic.com/szu23n.jpg
Thanks for the image, however, no way that's 5000mAh
especially scaling the two SOIC chips and approximating claimed capacity with other LIPO packs I have here,
another point to factor in, LIPO's are 3.7V, there's two in series here which ups the voltage to 7.4,
then some on-board DC-DC conversion to bring down to 5V
if just one of those packs is rated at (say) around 1500mAh, which is certainly reasonable considering the size, the overall capacity would be closer to 2000mAh at around 5V output
Still, it's a good price for what looks to be a well constructed unit, even if it's only 1/2 the capacity claimed
+1 to the OP
Can anybody read the code on the board… XCR 1030 ?
is that the correct code?
And the words "mobile power board" ?
SOOOOOOOOOOOOOOOO……
I just want to use this for iPhone, is it a good buy?
Check the reviews here - Most likely the same product.
http://www.amazon.com/5000mAh-External-Battery-USB-Charger/p…
As expected, much lower results than it suggests. However if you just want something cheap for emergencies then it be ok. The OP has the cheapest price I could find for it $11.40 AU shipped.
Thanks Jenniferds, bought 1 for my train commuting.
Anyone else have trouble with the billing? Even though I used the coupon code and my order shows US$11.89, my cc shows Card Authorisation AU$14.61.
my mistake. please ignore. Card Authorisation $12.62. If mod could delete my post above thx.
Item arrived. Less than 2 weeks.
Not happy about the item quality is absolutely crap, the connectors are bent and the battery pack is not charging to full it just keep blinking at 1 bar charged after 2 days! will be seeking paypal for recourse!
Do you have test results measuring the capacity with a multimeter?
It's not that I don't trust the claimed 5,000mah capacity… It's just that… Well, OK, I don't trust it :)
Plus, how long does it take to charge this thing?
EDIT: Haha, at least you are honest in the advertising: "almost reaching 5000mAh capacity" … So how close is 'almost'?
