eGo 1000mAh charging time with USB charger?
I keep reading about super fast charging times with the USB eGo charger, but my batteries are taking forever to charge, upwards of 5-7 hours, and it seems they're lasting less with each charge too. I just got them a few days ago so they've only been through three or four charge cycles each.
The only thing I can think I may be doing differently from others is charging directly off a USB port. I bought everything in pieces instead of getting a starter kit, and I haven't picked up a wall adapter yet.
Have others experienced this with the megas? Did I just get a couple of bum batteries? Am I doing something terribly wrong?
That is strange, given how new they are, it does make me think of bad batteries offhand, but it could be a faulty usb charger as well. It doesn't sound like you're doing anything wrong.
Try charging one of the megaego batts in a regular 510 usb charger if you have one, it will work, but take even longer. If they hold a charge better than with your ego charger, that may be the problem. I have the same batteries, charge them only on usb, and they never take more than 4 hours, in my experience. Somethin's up, for sure. At least they're pretty new, so you can exchange them, worst case scenario.
Alas, I have no regular 510 charger.
I guess I'll send TW an email and ask them about it. Just wanted to get some feedback from others before I started that whole process. If anyone else has any ideas, let 'em fly.
I have the same thing with a Janty eGo. The web site says that the charger is 2-3 hours. The only time I have ever done a charge in 3 hours was the first charge.
After that, they all seem to take 5-7 hours like you said.
5 - 7 hours (average that to 6 hours) is charging at 250mAh. Check the specs (output current) on your charger and see what it says.
All 3 of my universal USB chargers say an output current of 0.15A (150mAh). That's going to take a long time to charge a 1000mAh battery.
All I know is that this is what I'm supposed to have...

I checked the Charger I have. It say that the output is 420mh.
Of course, stickers can be printed for about .003 cents a piece. I have a multi meter but am not sure if it will check things that small. It isn't a very good meter.
I have one that looks just like that and it says the output is 0.2A (200mAh). If yours is the same it will take a bit over 5 hours to charge a 1000mAh battery.
As I said, look on the charger and see what the output current is. To charge in 2 hours like the site says the output will have to be 0.5A (500mAh) or more.
The USB port you have the charger plugged into can make a difference, too. If the USB port won't supply what the charger needs it will only supply what it's capable of, and that varies between computers.
If you're using an AC Adapter/Charger, make sure it's output is rated at 500mAh or more.
That should charge the battery in about 2-1/2 to 3 hours assuming a fully discharged battery.

Just "assume" the label is correct for now.

I couldn't charge my eGoXL at all on a USB port. I wired one up direct to my computer's power supply, and that works just fine -- doesn't do anything but supply power, but it has plenty of available current.
