Can the IdeaPad be charged using USB port?
I've tried to get info or charging the S2109 IdeaPad in the Android Users Forum but beyond the FAQ that says "most Android tablets can't be charged from the USB port" I get no response. "Most" clearly leaves some wiggle room, and I noticed that when I have my IdeaPad plugged into a USB port it at least says it's charging (although it can't be very cast because even leaving it for an hour or some doesn't change the charge level very much).
So what's the deal on charging these? Are you stuck with the 5V 2.5 Amps charger with the round plug, or can you use any of the USB wall chargers out there, and if so which ones? How about some converter from a wall charge USB to the round plug. Still 5V but lower amps. |

It's really hard to get an answer to this question for some reason. I get nothing over on the Android forum either. Strange.

If you're looking for USB wall-charger you might want to give these 5V/2A chargers a try. |

It looks like the S2109 can only be charged via the DC jack, which seems completely backwards considering it has a micro USB port and micro USB is fast becoming the standard charging port for such portable devices.

I wonder if I could use an adapter plug that goes from USB to the pin size used on the charging port? Same voltage but lower amps so it should work, just take more time. Or perhaps I could pair the USB to Pin adapter cord with a fast charging 2amp wall charger? Lower amperage should be safe. |

I also notice, however, that the charging icon and light comes on when the device is plugged into a USB port. That's sorta strange if it's not actually charging.

Just thought I'd update my own thread. The Lenovo IdeaPad S2109 will charge using the little Kindle charger, but it heats up quite a bit (the charger, I mean, not the Kindle). And the experience I have using a 5V charger with slightly higher amperage (1 amp as opposed to 0.8 amps) is that the IdeaPad gets hot, so apparently something is "odd" about the way the Lenovo gets charged through the micro USB port, and it's not just the amperage of the charger. Time for an engineer to weigh in, I guess?
The regular charger puts out 5V at 2.5 amps, or way more than either of the USB wall chargers I used. |
