Still waiting for my Silicone sleeve to arrive but here's mine anyway just for the hell of it.
Can I ask you where you purchased you're silicone sleeve from ?? I'm looking, but don't want to go the China route to get one.
It was off Ebay mate. If you need a link then feel free to PM me
Loving my Cubiod cubis set up.
But wanting more. Thinking of getting a smok tfv4 tank.
Any thoughts?
New to the 18650 mods. And temp control. Quit smoking a year ago with an istick 50w and kanger sub tank mini. And just recently tried the istick 40w tc but didn't work well and battery life sucked!!
Realize if I get the smok I'll eat juice. But the flavour will be worth it

It's taken me a month since starting this thread to finally order my very own cuboid! Vapenw gets the nod and I grabbed a couple of other goodies to go with it... Griffin RTA for $25 and a Smok BT65 for $15!
Has anyone done an endurance comparison between the cuboid and the mini? In my testing I'm getting very little more endurance from the cuboid compared to the mini. For my test I use the same rda with the same build and the same power settings on both mods. In the first round I got 1024 seconds of firing time on the mini and 1200 seconds on the cuboid. In my second round on the cuboid the batteries were finished in 1100 seconds. The mini us using an lg he2 3000 mah. The cuboid is using a pair of 2400 mah batteries that are more used but seem to be in good shape and within .03 volts of each other. I think the difference shouldn't be so small. I encourage others who have both devices to so this test so we can compare notes. May be series setups have an efficiency loss.
The mini has enough power to get me through an entire day. The cubpoid does the same but is done by early morning the next day.

What exactly are the batteries and how old are they? Have they always been paired? What power settled? And for the battery in the Mini I'm assuming you mean hg2, not he4?

FWIW, the Cuboid has the two batteries wired in series, so having the two batteries will not double your battery life. It doubles the amount of power that the batteries can safely produce.
In a regulated device series and parallel are effectively equal. Using two 2500 mAh batteries, in a parallel setup you'll have 5000 mAh at a nominal 3.7v. In a series setup you'll have 2500 mAh at a nominal 7.4v, half the mAh but double the voltage. As current is traded for volts, and vice versa, to produce a certain wattage, the amp hour capacity is identical.
5000 (2 x 2500 mAh) x 3.7 / 1000 = 18.5
2500 x 7.4 (2 x 3.7v) / 1000 = 18.5
Edit: and in an unregulated device a series setup does not double the power that can safely be used. Quite the opposite. The voltage is doubled so the amp draw (and wattage) significantly increase with the same resistance coil. But that's on an unregulated setup.

SAMSUNG INR18650-25R.
If there isn't significantly more endurance I bought the wrong product. I never go above 30 watts. Is the only benefit of 2 cell mods high watt operation?
A two-battery device, whether series or parallel, should give you roughly twice the runtime of a single-battery device. In theory, and all things being equal, which they never are. Your LG hg2 is a higher capacity battery, your 25r's might be damaged (or mismatched), or something else.
Say, for example, that your 25r's are degraded to the point where they give you only 2000 mAh a piece whereas the new LG hg2 gives you the full 3000 mAh (that's in theory, you'll never get to use the full capacity, which also differs a lot depending on the strain on the battery). You'll have 3000 vs 4000, not vs doubling of the capacity.

I operated both devices from a fresh charge, with identical power settings and the same rda with the same build, without recharging, until they stopped firing and noted the firing time in seconds that the devices provide. In the first round test the the mini went 1000 seconds and the cuboid went 1200 seconds. I'm not saying my result is definitive. I'm asking others who have both devices to repeat my test and we'll compare results.
I hope my results are wrong because I got the cuboid for endurance, not higher watts.
As I said, you need batteries that are equal in age, use, and capacity.

Very good explain K, and example. Thanks for the bunch.
Checkin' one of these out and a great vape, heft and feel. Love the form factor which is quite remarkable. Just a wee bit concerned that the flip-door might be a bit delicate if you do a lot of batt swaps. I'd rather see a solid metal slide with solid (as in rugged) contacts. Just wonderin' what took 'em so long. Like the Cloupor GT80 for its practical size too. Only adequate power handling tho. Regardless both great value for the bucks.
Good luck all.
I will test out my set of fully charged Samsung 30Q and report back. Incase peeps are wondering, select the time setting and hold the power button and it will reset your counter.
Anyone own both the Black and Silver versions and can comment on the differences in finish between the two?
I don't have a black one yet, it's still enroute from China. I did receive my silver one today that I ordered from VapeNW & I sure hope that the black finish is more durable then the stainless!! This thing's got scuffs all over it right out of the box! I really don't mind cause most of them are pretty small and this thing really didn't break the bank money wise. I already updated it to 200 watts & it works really well.
