I did a few tests this afternoon.... USB 2 and USB 3 had no bearing on whether the light turned green or red... mine stays red and dims by about 1/2 at full charge. I had previously drilled a hole beside the usb port on the clone so the led was very easy to see.
And on the performance I did the following:
Put together a new carto tank with 3.0 ohm carto. Checked the ohm's of the carto with a ohm checker and meter and both read 3.0 ohms.
Plugged in 8.5 watts @ 3.0 ohm's into my Ohm's Law calculator and receive the voltage answer of 5.04975 volts.
Set my real DNA wattage to 8.5 watts with a fully charged battery. Set the Clone to 8.5 watts with a fully charged battery.
Screwed the tank onto the real DNA and pressed the fire button. Results from the display was: Wattage 8.5 Ohm reading 3.0 Voltage reading 5.1v (5.04975 per ohm's law calculator)
Screwed the same tank on the Clone and pressed the fire button. Results from the display was: Wattage 8.5 Ohm reading 2.7 Voltage reading 4.7v (4.79062 per ohm's law calculator)
Screwed an in-line voltage meter onto the real DNA and screwed the tank into it. Fired with same 8.5 wattage setting and the in-line meter read at 5.1v. The dna display read 5.1v. (5.04975 per ohm's law calculator)
Screwed the in-line voltage meter onto the Clone and screwed the tank into it. Fired with the same 8.5 wattage setting and the in-line meter read at 4.6v. The dna display read 4.7v. (4.79062 per ohm's law calculator @ 8.5 watts )

My
final opinion is that the clone enclosure, battery holder, and buttons are good. The rest of the internals and 510 connector are not ready for prime time and may be dangerous.
Conclusion is that
I cannot and will not recommend this device (logo or non-logo version).
Supporting information being added with this post:
Issues and/or comments reported either here or elsewhere:
1. Milling process of the enclosure allows swirls in the drip well and fire switch areas.
2. Removable back plate of the enclosure may not fit smoothly in all devices.
3. Screws used the back plate are of poor quality.
4. Threaded hole to receive the back plate screws are stripped on some devices.
5. 510 connector center pin is not properly sized in width thus allowing possible short circuits to occur with certain toppers.
6. 510 connector not installed flush with the enclosure thus allowing slightly tilting of toppers on some devices.
7. Battery holder can become dislodged from enclosure due to the use of less effective attachment securing media.
8. USB port can be dislodged from enclosure due to use of less effective attachment securing media.
9. Fire/up/down buttons can become dislodged in some devices due to the use of less effective attachment media.
10. On some devices the attachment media used to secure the clone dna board in the enclosure is applied over board components that radiate heat during operation. This can allow heat buildup.
11. USB charging board leds are not properly fitted and/or the enclosure does not allow easily visual indication of charge state.
12. When pressing the fire button to allow the unit to operate from sleep mode two or more presses are required.
13. When coming out of sleep mode it is noted that the wattage setting has changed on some devices requiring resetting the wattage each time the device comes out of sleep mode.
14. When the device is in locked mode and it comes out of sleep mode with the power lock function activated the power lock mode is no longer activated in some devices.
15. When the device is in sleep mode and left unattended it will come out of sleep mode without any button push by the user on some devices.
16. The on board temperature sensing circuit activates at a higher rate of occurrence compared to the real dna.
17. The ohm reading on the display does not accurately relay the true ohm reading of the coil it is measuring. The variance may be small or larger depending on the clone device as there is no consistent variation.
18. The voltage reading while firing displayed is different that the voltage actually reaching the coil.
19. The warranty contained in the instruction sheet indicated a manufacturer warranty of 90 days. This has not been confirmed however vendors warranty periods are all over the map from DOA to 7 weeks to ?????
20. Logo devices and those that display Hana Modzs on the display seem to violate USA trademark laws. Some vendors have gone underground and China is still sending them and vendors are still selling them.
21. The Clone is reported by many to put out less power that the real dna at the same wattage setting. A scope analysis will eventually compare them to either confirm or deny this claim. My experience confirms this assumption.
I know I have probably missed a few more things so this is not a complete list. Having researched, used, tested and compared many, many devices over many years and building many devices myself I reached my conclusion trying to take all aspects into consideration. This device exhibited more concerns to me than any other device I have used or have memory of. I do not expect, nor intend, that you adopt my conclusion. I only present it as MY CONCLUSION.
My Conclusion Post was intended to be my last post here so I only give you this one in an effort to inform and provide additional information, most of which is already spread throughout this thread.
Have a great day
