三星Galaxy Tab的负载电流为2a，但是 USB-Compicisimication仅允许整个总线500 mA。

电池充电规范1.2于2010年12月发布。几个 更改和增加限制，包括允许1.5 A充电 针对未配置设备的端口，允许高速通信 提供最多1.5 A，<强>的电流，并允许最大电流 5 a
所以，什么样的USB电缆应该用于充电三星Galaxy平板电脑，例如三星Galaxy片剂2（GT - P5100）
From Galaxy Tab is not being charged through USB Cable
@Chris Stratton
Tablets have larger batteries than phones and may be unable to sufficiently charge from the half amp limit of a USB port, especially while they are fully on (screen on and full speed processor clock).
Some will barely charge if the screen is off but come with high current 5v "usb-like" wall chargers, others use a higher voltage charger on a custom connector - typically something round. Sometimes the "usb-like" ones are actually special cables with extra pins that tell the tablet that a special high-current charger is being used.

The Samsung Galaxy Tab has a loading current of 2 A, but the USB-Specificication only allows 500 mA for the whole bus.

@USB 3.0
Battery Charging Specification 1.2 released in December 2010. Several changes and increasing limits including allowing 1.5 A on charging ports for unconfigured devices, allowing High Speed communication while supplying a current up to 1.5 A, and allowing a maximum current of 5 A
So, What kind of USB Cable should be used to Charge Samsung Galaxy Tablets, for example Samsung Galaxy Tablet 2 (GT - P5100)
我不认为电缆尤为重要。它的电缆插入其中的 jack 有所不同。
基本上，如果平板电脑可以告诉它插入特殊（高amp）千斤顶，那么平板电脑将更快地收取（在2A），否则平板电脑将其插入标准USB端口并充电规格限制（500 mA）。获得平板电脑可以识别的适配器的最佳方法是使用官方墙壁适配器。我相信没有"标准" 的方式，所以不同的制造商可以做不同的事情（例如，使用Apple USB充电器可能无法正常工作）。
您应该能够查看您的平板电脑根据系统托盘中的电池图标（假设它类似于我所拥有的较旧的Galaxy Tab）。在我的平板电脑上，如果它通过"正常" 连接充电，则该图标将具有小红色"X" ，如果它不应通过高度放大器连接充电。
看星系选项卡10.1充电器需要提供多少电源？
和 do samsung平板电脑与Apple的iPad相同的USB连接器？
和为什么使用USB充电比使用出口慢的计算机？
I don't think the cable is particularly important. Its the jack that the cable plugs into that makes a difference.
Basically, if the tablet can tell that its plugged into a special (high amp) jack, then the tablet will charge more quickly (at 2A), otherwise the tablet will assume its plugged into a standard USB port and charge at the specification limit (500 mA). The best way to get an adapter that the tablet can identify is to use the official wall adapter. I believe there is no "standard" way of doing this, so different manufacturers may do different things (e.g., using an Apple USB charger may not work).
You should be able to see what your tablet is doing based on the battery icon in the system tray (assuming its similar to the older Galaxy Tab that I have). On my tablet the icon will have a small red "X" if its being charged through a "normal" connection, and should have no such "X" if its being charged through a high-amp connection.
See How much power does a Galaxy Tab 10.1 charger need to supply?
And Do Samsung tablets have the same USB connector as Apple's iPad?
And Why is charging from computer using USB slower than using an outlet?
三星平板电脑没有右充电器都无法充电。充电器用你的平板电脑给了你，如果你丢失它，你必须购买一个适合的新人，因为有许多充电器很宽但不适合三星Galaxy标签。因此，如果您没有充电器，您必须购买一个或者您的平板电脑将不会被充电，直到您这样做。
Samsung tablets are impossible to charge without the right charger. The charger was given to you with your tablet and if you lose it you have to buy a new one that will fit because there are many chargers that are wide but don't fit into Samsung Galaxy Tabs. So if you don't have a charger you have to buy one or else your tablet will not be charged until you do so.
