First and foremost, this is not a "zomg, I got sent a bad item and I'm gonna cry about it" thread. :p
This is simply information being provided about a piece of hardware, so that consumers can take appropriate safeguards. If this has been covered previously and my search missed it, I apologize.

*It should be noted however, that these observations should NOT be considered eGo specific, and may apply to all USB chargers of this size & shape.

The Facts:

1. Since the moment I recieved my eGo kit, I've handled everything with "kid gloves", and ensured I was NOT overtightening or rough handling the hardware at any time.

2. From the first charge, I noticed that the eGo USB charger was "acting up", and not changing to the green LED when the battery should have been charged completely. At first, I simply thought it was an eGo specific quirk, or worst case, juice in the connection.

3. I had to "wiggle" the battery (after charging for hours), or slightly loosen then re-tighten it to get the LED to change to green (charged).

The Findings

Case gap

I normally held the charger down on the shelf in front of me as I screwed a battery in, so I wasn't seeing this gap at first.


Flush screws

After seeing the gap, I compared the eGo charger to a regular 510 (150mA) charger, and noticed the screws were not recessed.

Opening the case, I found that;
  • The screws were in as far as they could go, and the tapered end of the screws barely cleared the circuit board.
  • Even though the screws barely extended past the board, both screw holes on the opposite case half had been broken. (The broken case section simply fell off as I separated the 2 halves)
Tape ftw

The Fix - 2 Birds one stone?

I had considered ways of "marking" the eGo charger, as a visual quick reference to avoid grabbing the 510 charger by mistake. 100 m.p.h. (duct) tape seems to fit that bill fairly well. :evil:

“All of life’s problems can be solved with two things—duct tape and WD40. If it moves and it shouldn’t, you need duct tape. And if it doesn’t move and it should, you need WD40.”—Unknown

I'm having the same problem, after the first charge my light will not turn green even after 5 hours on the charger.

I couldn't quite figure out if you were able to fix yours or not.
YES! (sorry so late on a reply) :oops:

I re-wrapped the connector with the duct tape, and sucessfully got a Red-->Green charged status.

If a battery has been on the charger long enough for a complete charge, squeeze (forefinger & thumb) the charger case close to the battery connector, and see if the light changes to green.

If it does, then the case is likely separating enough to cause a loose connection with the battery.

***Can anyone else compare the eGo & 510 USB battery chargers (corded), to see if the 2 screws are the same depth? I only have one of each.

Also, anyone using these charger adapters yet?

Great, thanks! I don't think mine has that gap but I will check.

What I did figure out today is if I only screw the battery in until the button on the batt itself starts flashing then it will turn green when it's done charging. If I screw it in until it stops it will not turn green.

ETA ... my charger doesn't have that gap :)

I use the charger adaptor and love it, I can use one of the pile of regular 510 chargers that I have from all the no box kits I have ordered and the 5-6 hour charge time makes zero difference since the battery lasts longer than my long charge time.

I have also seen some of the tech guys say the slow charge is better over the long run for the battery, I have no idea if that is true or not but it sounds reasonable.

I have been doing the same with both USB chargers, but adding another 1/8 - 1/4 turn to ensure the connection is solid.

Good to hear you are "gapless" :p

Thank You for the input!

Coming from a communications background in the military, I will agree that the slower/trickle charge is probably still better for batteries in the long run. I know composition has changed over the past few years (NiCad, LIon, etc), but I have never heard of a slower mA charge being bad. :p

FWIW- I am thinking these adapters used with the multi charger will be an awsome idea. Not only is it hard one-piece plastic at the connection, it will also keep the battery vertical, so there is no stress on the threads/connection from battery weight. :thumbs:

Once again, thanks for the helpful info, and I invite others to continue listing their experiences.
