If you have ever charged your iPad via your MacBook Pro you may have noticed that the top-up times are extended from that of the standard wall-mounted charger.
According to Softpedia this is down to the fact that the previous generation of the Pro gives 500mA with an “Extra Operating Current” of the same, therefore producing just 1000mA charging power.
However, with the release of the latest edition of the MacBook Pro, these charging times have been dramatically reduced. A report by 9to5mac states that whilst still giving an available 500mA, the new Pro offers an extra 1600mA of power totalling 2100mA. This is almost identical to the iPad’s mains adapter.
Obviously if using your MacBook to top up your iPad your performance will be impaired, but it’s nice to know that if you need to the option is there, rather than carrying your mains charger everywhere and having to find a domestic output.
There are a number of tips for charging your tablet on Apple’s Support pages. It confirms that the best way to charge is via the standard power adapter, but if necessary a computer with a high-power USB port (like the new Mac range) will suffice, although you may suffer slightly increased top-up times.
It also states, “When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it’s in sleep mode,” and adds, “Make sure your computer is on while charging iPad via USB, if iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.”
If you want to charge via your netbook it’s worth noting that the device must be connected to the mains and not in standby, sleep or hibernation modes.
