There has been much written about the so-called “wal wart” chargers that ASUS has been supplying the TF101 with.
Having said that, the TF101 is a great product, and I’d like to find a way to move off this dependence.
As I’ve only had the TF101 for 24hrs, which is now up to 20% charge (trickle charging from a USB 2.0 port) and can’t charge with a my now broken 0B-2LF “wal wart” charger, please forgive my ignorance on some things. New to tablets, but been a Android phone user since the HTC Magic days (yay to r00ting).
What I would like to understand better are all the parameters that need to be met for the TF101 to be charged while it is still on, and would appreciate any advice people have from experience.
I’ve been using an app called Dual Battery Widget (when you click on the widget it lets you know whether it is charging or not, as I don’t know what a what the visual indicator for a turned on charging TF101 is!). Note also so far the only way I’ve been charging is via a standard 5V 0.5A USB 2.0 ports with the TF101 completely turned off. Rate is about 1-3%, and that from I can tell from various threads in this forum is normal.
One thing I have noticed is that USB 3.0 plays a large role. Is the charge cable supplied by ASUS a spec compliant USB 3.0 connector on one?
I have noticed various comments suggesting that a recent MacBook Pro with a USB 2.0 port can charge a TF101. However, is this with the TF101 turned on? There are suggestions that recent MacBook Pro’s ship with a 10W power supply on the USB 2.0 ports.
Has anyone tried using a USB 3.0 Hub (like the Unitek product from Jaycar – cat no ) with a 5V 2A power supply to charge the TF101 while it was still on?
Has anyone found a way to deliver 10W from a USB 2.0 or USB 3.0 port without using an Apple charger?
Things I’ve tried with my TF101:
An Apple charger, USB 2.0 and rated at 5.1V 2.1A, and didn’t charge my tablet – has anyone been able to charge using Apple products?
Dell XPS 14z USB 3.0 port, and it didn’t my charge. I have no idea what Dell supplies as max current on a USB 3.0 port, USB 3.0 spec only requires 0.9A max to be supplied, though more can be supplied for sure.
About 30 different USB 2.0 ports (PC’s & laptops of different ages, phone chargers, etc).
Finally – do I possibly have a malfunctioning tablet perhaps that can’t be charged?
