So why post all that irrelevant stuff?....and the ignorance about 220 volts would charge faster than 110 volts?...when in fact it will fry the device that was designed to operate on 110 volts? Abeg... modify your posts before people follow your enlightenment and damage their devices.

1. I think the frequency of the AC matters alot. A relatively low frequency will damage your appliance not just batteries alone. The higher frequencies means that the AC and DC produced is smooth enough for safe operation of your electronics.

2. Another source of instability might arise when load (your electronics) is imposed on the generator. The magnetic flux used to generate current is not sourced from a permanent magnet but an electromagnet which means that part of the current generated is used in creating magnetic field. This could alter the balance of the circuit if a controller (AVR) is not in place to restore balance.The problem here is that most small gens e.g tiger, honda etc don't usually have AVRs and so an unsteady AC and DC is produced.

In summary, the unsteady current due to current fluctuation is what damages your phone batteries. How does it damage your batteries? I have the following theories from a chemical engineering point of view.

1. First of all, direct current is what is used to recharge/restore the potential of batteries through a principle known as electolysis. A steady state current demands that the ions of the electrolyes at the cathode terminal are properly disengaged and restored. An unsteady system will result to a haphazard molecular arrangement of the electrolyte lattice which will reduce the performance of the battery.

2. Unsteady flow of current might lead to a break down of the components that make up the battery because of difference in 'coefficient of expansion' of the battery components. You could notice this by the unusual rise in temperature of the battery when charging.

Note: coefficient of expansion is just the ability of a material to increase in size on the application of heat. Differences in this ability may result in hobbling of the army of molecules in the said appliance or device.

Well deduced but electric current is measured in amperes not volts. Electric voltage is what is measured in volts. A simple explanation, imagine water flowing through a pipe, the rate at which the water is flowing is similar to current while the pressure of the water is just like the voltage.

Small generators usually have too many fluctuations (voltage, frequency) in their output that's one the reasons why they are not always advisable to use for charging phones and other sensitive electronics.

Final thing. Yes it is true that phone charges are said to accept voltage inputs between 100 - 240V however note this, the lower the voltage the more the current it will draw. This is why it is bad because high currents can damage the charger easily (or blow the fuse). By damage I mean burn it.

GraGra247:
It damages both laptop and phone batteries, charger and sometimes components.

Proven by thousands. Ask a phone repair professional.

The culprit is the irregular flow of fluctuating current from the tiger gen.

DameB:
11 (elebin) yearz... Dayum..... That generator na ancestor. This na real case of when you find that special one don't let it go.

Lol.

But on a lighter note people complain about gen not being good for phone batteries.
Maybe adding a stabilizer will give your customers better assurance

romeo1000:
Electric current is measured in amperes not volts.
Volts is d unt of potential difference

Oga stop displaying and preaching ignorance, which phone engineers? The ones who never saw the four walls of any electrical engineering classroom?
Size of generator will not affect your battery except your phone or laptop charger or the phone is faulty.
AC power from mains supply socket at 220v gets into the charger, no matter how much harmonics accompanying the fundamental frequency, the stepdown transformer converts it down to either 12v or less which is still AC power, the diodes which may be configured in half bridge or full bridge will convert it to DC but this DC still fluctuates because diodes allow electricity flow only in one direction, your charger will now use capacitors and sometimes inductors but they are obsolete now to filter the fluctuating DC, the capacitors filter the DC by charging at one cycle when the diode is conducting and discharging at the point when the diode ain't conducting thereby ensuring the DC voltage and current has definite or clipped amplitude. This good DC electricity is now passed through a regulator of 5v that produces pure DC for your phone to charge. This is how it happens even if you use an inverter that produces square wave. Generator has got noting to do with your battery.
Your battery will get bad when you are using it while charging it because of heat and you shaking the cord input to the charging port that Sparks.
Be guided.

GraGra247:
Mr know it all, nobody asked about faulty generators. The topic is directed at well functioning tiger generators.

Please tell us why tiger generators in their best function still damage appliances, chargers and batteries.

Oga, in my 11yrs of using small gen to charge my phones and laptops, non of my original chargers have ever burnt.

Speak for yourself then. Allow we victims to either find solutions or just carry our cross.

1000angstroms:
You are asking him to speak for himself but you are using "we" when making your own statements, talk of double standards.

1000angstroms:
Then am putting it to you that a well functioning tiger generator will not and cannot harm your battery.

GraGra247:
Escape strategy!! Since obviously you can't provide technical explanation. Yet you're Mr know it all.

I also put it to you that a well functioning tiger generator damages appliances for which I've witnessed many times.

If you can't explain it simply humble yourself and declare "you are still learning like everyone else"

lordskid:
You never stated any valid argument, bro! What do you think is the CAUSE? Who knows, your argument might help us adjust our wrong notion.

You don't need to attack me, attack the argument, bro. That's how we all LEARN.

1000angstroms:
You are the one that does not want to learn, you claim it damages yours, then someone up there already attested that in his 11 years that it has done no harm to his phone and I am also another witness to what he said cos my own phones and chsrgers have been perfect even though I use the same tiger generator you talk about. In evidence it is 2 - 1 and you still want me to give you more facts or what again did you say, I should humble, mtcheeew I can't argue with you again, I wanted to teach you something I studied all the way from undergrad to masters level but it ain't enough for you. Then I can't help you any further.
