[TEST]Heaven Gifts M401 w. Standard+USB-Battery

[jussumdood]

My Smoore built 401 on their passthrough+ dipping rocks with cart instead of dipping

+First try with USB-Battery fine, slighter and lighter weight and better cord, draws lesser power from usb port cause i cannot hear the laptop's voltage converter as before with the DSE103 USB-System.

Untrue, draws enough power to damage a USB 1.1 port over short or long time.

Use with USB >= 2.0 ports with sufficent power supply, only.

BTW, cable is somehow integrated in the USB-Battery's circuit, usb extension cords lead to malfunction.

Yep, my 401 atomizer sizzles on second drag of new battery like bacon frying.

I personally like cleaning cycle. Haven't had a 401 atty die in 3 months

WARNING!
This means the HG AC/usb-adaptors cannot be used for HG M401 USB-Batteries with USB extension cords.

Can anyone confirm this?

I've build my own from a 12V/1A AC-adaptor with long cord to a car cigarette lighter plug USB-Adapter (Europe).

I have Heaven Gifts M401. Attys still going strong since Oct.7. Only cleaned them once in Crest. Like new then. I'm pretty sure HG 401s are Smores. Forget where I read that... duh...

Atomizer lifetime, ... will be reported.

Nearly one month now, survived all 3-day aux power burn cleaning cycles, multimeter shows heater element regression: New 2,5-3 ; 3 Weeks 2-2,5 OHMS. Some wires seem damaged / short circuited or low electrical resistance liquid coal bridges between the wires.

M401 USB-Battery still fine, too.

Atomizer regression now, possible reason:

HG's M401 Batteries have got autocleaning . USB-Batteries not.

Both my batteries do a short atomizer power burn cleaning after the 1st few puffs after charging or on first use.

Compared with DSE103's system the process seems not to damage the atomizer.

Cycle time unknown so far since I use USB-Battery mostly.

UPDATE:
Atomizer #1 died today, autocleaning + liquid crust killed it, heater element melt breakage.
But acceptable MTBF (lifetime) > 1 Month under chainsmoking load.

HG's M403 battery arrived, cool for downtown, really smart&small.

[Taelon]

Atomizer #2 good lifetime, too, ~1 Month.

Atomizer #3 +#4 from last HG shipment heater element quality problems (2-3 wires red glowing, other wires cold) , burning liquid with usb battery, smell still nasty with Li-Ion Battery at lower supply voltage, possibly inhaling poisonous burned liquid, trashed them

Atomizer #5 ok.

Will order 4 more and change model again to good old DSE901 if not better.

So before we trust such industry sponsored studies,

chinese manufacturers (are there other? not rebranders) should really get more commited to quality.
