Why iPad cann't be charged on computer?

Many iPad users as you may meet a problem that the iPad newly purchased cann't charge on the computer.Not really,actually,iPad can charge on Apple mac computer.In theory,your computer can charge your iPad,but the output current of ordinary computer is lower than iPad,we usually have ordianry conputer such as sony,HP,Dell.These computer's output current is about 500 mAh.So it must take a long time to charge your iPad,iPad2 battery capacity is about  6000mAh,so it many need 12 hours to charge fully,while iPad need 1A output current to charge normally,otherwise itS current is too small,so you cann't see and your iPad will show the status of not charging,actually,it is charging.But need long long time.

To solve this problem,you can plug your iPad on the wall to charge,but it's unconvenient for you to play iPad.Because you need to find wall plug.Now,there is another way to solve this problem.That is iPad USB charger--can charge your ipad on any computer,and the output current is 1A,can reduce  the charge time for half.As far as I know,at present,there are several manufacturers that produce such product,so many people don't know about this product.They endure long waiting for charging your iPad fully.I have found it on amazon for you.

The price of this brand is higher than XMultiple,but its product review is good than XM.But still there is a problem that it cann't switch between charge and sync modes without unplugging the adapter when you wanna sync,so you need to unplug it before switch modes.

How to Distinguish the Inferior Cell phone battery?

Currently,there are three kinds cell phone battery in the market: the lithium ion battery, the nimh batteries and nickel batteries.Lithium ion battery capacity is the largest, long standby time, light weight,is the mainstream variety of cell phone battery. In order to use the low price to attract consumers,many manufacturers sell inferior cell phone battery to customers.Now you can distinguish the inferior cell phone battery from the following aspects.

The length of the standby time
The length of the standby time of cell phone battery is a important symbol to measure the quality of battery.The length depends on the balance of monomer chargering battery.The standby time of real battery is consistent with instructions.Some inferior battery use second-hand battery core as kernel,then assembly new packaging.If sellers can not  guarantee standby time is consistent with instructions,then you don't buy it.If you find the standby time is too short,you should request to return goods.

Battery Capacity
The cell phone battery capacity general has two kinds-1000ma/hour or 1000mah.Some fake battery has no capacity marking,and some has unclear signs.Sometimes you can take your battery to repair shops to measure current to identify the false.Now the cell phone battery that people use is lithium battery,and mobile phone lithium battery is generally use lithium-ion polyer battery,match with switch mechanism and protection of circuit.So it has a certain weight.If the battery you bought is too light,then can explain the battery core capacity is not enough and this battery may has problem.Generally,900 mah lithium battery core weight about 35g.If a battery core plus battery case and other equipment weight less than 35g,then the battery is false.

Safety
The cell phone battery is flammable and explosive substances, if the battery interior does not have the protection circuit, is extremely easy deformation, leakage, even explosion. However,in order to use the low price to attract consumers,  many inferior battery take out the circuit protection board,to earn more profits.There are many such fake batteries in the market,it is difficult to identify false from the outside.It's better to buy from credible sellers.

Appearance Distinguish
The general problems of fake battery is the core component of battery, poor quality of battery chip, charge is not enough, short time of discharge , the destruction resistant performance is poor, that are standard battery capacity and the actual discrepancy, etc.Now the market is flooded with fake [b]cell phone battery[/b], that damage many of the interests of consumers . The salable cell phone battery has the following characteristics form the appearance: the battery labeling using two printing technology, in a certain light, from cant see, bar code is obviously more black than other parts, and with the hand up, feeling a little convex than any other part, many original battery all have this feature.If you use  metal to scratch the white surface gently, it will appear similar traces of a pencil scratched. The battery shell is made of special materials,very solid,not easy to damage, usually not easy to open the case, the battery appearance is very neat, no extra burr, outside surface has the certain rough but feel comfortable, inside surface feel smooth,  can see fine longitudinal scratches in the light.
The battery electrodes has the same width with cell phone battery piece, marked with "+" and "-" signs below battery electrodes, isolation materials between the charger electrode slice is the same as the shell materials, but not one.You will feel comfortable and freely when you put the battery into the cell phone. Press part of the battery lock is appropriate and firm. The battery labeling has clear the handwriting,has corresponding battery package number with battery type.The battery manufacturers should be outline clear and security sign brightness good, look solid.
