I use the usb port on an alarm clock I ran across in a Walmart some time back. It had two ac outlets with an on/off switch plus the usb port. The port is adequate and originally must have been intended for cell phones but works well for charging eGo batteries and mods. I already recharged the E-LVT since i was vaping with that since it came in friday and all day yesterday.
There will be either a green led or the lcd display will see something scrolling back and forth on that during the charging until completed. Plan on about 2 1/2-3hrs. for a full charge and then the mod will go dark. These mods have the mini charger in the circuitry to allow this as well as automatically turn the charging off once the battery is detected as full. That will save on the need to keep removing the cover.
The port on the alarm clock as well as the ac wall plugins like Belkin you find in the electrical dept. at a store like ACE or Walmart have a higher amperage then the pc ports. Generally those are found to be between 750mA and 1A on average being intended to handle the draw a cell phone, smart phone, IPony, digital camera, etc. will place on them. While with high drain batteries I would prefer to continue rotating them to allow each battery to sit for some time before used again I won't be using the DovPo constantly as the only mod or one of few since I leave each rest for a few days having the others to work with.
As for Efest that's not a bad brand but forget using them on any aluminum mod or mechs since the batteries are simply too large in diameter. The 18650s were originally designed for heavy duty flashlights to begin with and the need to limit the diameter in those just wasn't there years back. Here's a look at an 18650 led flashlight with a 2 for one offer at the moment. The short video clip shows how those are used for camping or for security guards, etc Voidhawk‚
