the battery is 2200 mAh and you would just have to find out the battery capacity of your cell phone. The unit with 2200 mAh will theoretically have enough juice to charge one iPhone 5 to 100% and still have enough juice left to charge another iPhone 5 to 50% as the iPhone 5 battery is 1440 mAh (2200÷1440=1.5). If you have a Galaxy S4 then wikipedia lists the battery as a 2600mAh capacity so the WakaWaka will only charge the phone up to 84% theoretically. The real world numbers may be less depending on battery and ambient temperature and other factors.

I cannot answer exactly. I charged my wifes Samsung c/p in 2-3 hours and the light was still bright on the charger but it will not charge my 7-8yr old motorola razr so don't know if it will do both. It does have a usb and mini usb port so if you have both cables it would be worth a try. If you leave it in the sun while you are charging the phone it would help.. Go to the Waka-Waka.com website and ask them the question.

Dont know have not tried as I have this for either emergency use or backcountry use and one cellphone is enough. I would say probably it would charge two phones since it will charge a phone and still give you hours light on one charge, but if you juice up two phones that will probably mean no light. Real world results will vary as will the phone you use. If you are depending on this for emergency or life critical issues and actually need to charge someone elses phone, then emergency protocols typicaly dictate that person should have their own and you should not be sharing. In other words stop being cheap and do the right thing. Dont know have not tried as I have this for either emergency use or backcountry use and one cellphone is enough.

Yes, but it takes most of a full power cell to get a full charge from almost dead. Other smart phones I've been able to get 2 to 2 1/2 phones per charge.

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.

My apologies for the delay in responding. I looked for the boxes & I looked online but can not answer your question. I will add though that based on all I'm reading, I do not expect these units to be able to charge our phones, laptops, etc. fully on a continuous basis. I bought them for emergency use when I've miscalculated or forgotten to charge my device & must use it at that moment. I has filled that purpose for me quite well. I've powered up 2 different LG phone models, a Samsung S3 & some sort of older phone issued by Verizon. All were able to make the calls I needed. So far so good.

I tried charging two at once and it didn't work. I think what was really intended is the one mini/micro whatever it is connection on the face is the only charging connection... On the positives, its a neat little device and I do mean little, the power adapter is much bigger than the hub.. I would still recommend buying it just based off its overall size and portability, I just kind of like the thing... Sorry no I dont think its capable of charging two devices at once.

Yes. At home we charge a 4 and 4S at the same time. I see no reason it would not charge 2 4Ss at the same time as well

I was able to fully charge my android smart phone twice and my itouch ipod twice. I purposly ran both devices down to about 10% charge left. I was curious myself how many charges i could get out of the little battery. The external battery still showed 1 bar left out of 4 bars so i might have been able to get a 5th charge out of it. hope this helps. I bought one for my wife and she loves it as well. We go tent camping alot so it comes in handy for sure.

This device can be used to charge 2 phones at the same time. It states that it can charge a phone and an iPad at the same time to describe the amount of output the device has but 2 phones will charge just fine.

yup, works fine charging both at the same time. Make sure you got one bank to one battery and the other bank to the second battery(in other words, don't mix the two banks from the charger up).

You can only have two phones connected at once, and it gives you the option of selecting number 1 or 2. You have to know/remember which is which. I rarely dial out on cell from these phones, but often will answer using them. It works great, but the cell phone needs to be relatively close to the base (15-20 feet). I keep mine on a charger about 5 feet away.

This model sucks as far as that is concerned get the one off ebay that doubles ad a jump pack and laptop charger. But to answer your question It only charges one at a time. The two ports are a 1.5 amp and a 0.5 amp port either way I have had devices on this thing and they never filled up... they will continue running but filling one up is never really easy... also check into spare batteries for your phone on ebay... they are usually only like $5.00 so good deal...

it's best to work in pairs. ie if you have 4 batteries, put 2 on one side, and 2 on the other. This allows faster charging as there's a fixed amount of current available on each side, so balancing the load when you have less than a full load will charge faster. Batteries are in correctly when charging icon blinks, complete when all bars steady. That's about it, unless you want all the legal don't do stuff (dont stand in water and operate device, and so on)

It will be fine. Your phone will only draw the current it needs to charge. The nice thing about this one is that it can charge two phones at once. Or other devices--iPads, Kindles, etc.

Hello:I bought two units. I always have one charging when the other runs out. I have not tested the unit in the charger. The battery life is excellent (more than 24 hours). I don't use the unit as the main telephone (answer or call regular everyday life situations - only for an emergency). Every time I want to make or answer a call, I do it from the wireless telephone or the main telephone (Base).Regards;Ino

Hi Peter Yes, you are quite right. I hadn't tried that but my unit will not do both at the same time. In practice I have a dual USB charger so the need has never arisen. Regards Richard Allan.

Hi, it does not charge t the same time both, I think it does not functioning anymore after 4 or 5 charges... Not recommended.

it charges both at the same time:) and it will stop charging one once it's full.
