Hi Ryan, and welcome to ECF!
My recommendation for an eGo power unit - i.e., something similar in design and execution to your eGo-T but with many more features - is the
SLB eGo-V V3 Mega. It is the finest eGo-style device I've ever seen or heard of. Of course, there may be something out there that I haven't yet seen or heard of in terms of an eGo power unit. But I've seen and researched many devices in this category before I decided on this one.
And although it's one of the more expensive ones at $36.99, it's well worth it in my book. I absolutely LOVE mine, and I reach for it more often than anything else in my collection.
Here is a link to a detailed description of it that I posted in another ECF thread.
I'll summarize its features below, several of which set it apart from other eGo devices and even some full-scale mods:
-- Large capacity 1300mAh battery
-- eGo and 510 threaded
-- Variable voltage (VV) 3.0v to 6.0v in 0.1v increments (most VV eGo's have a shorter 3.3v to 4.8v range)
-- Variable wattage (VW) 3.0w to 15.0w in 0.5w increments (most eGo's don't do variable wattage at all)
-- 2.5A maximum current (most devices I've seen have a 2A maximum current)
-- LCD display and two lockable buttons (+/-) for feature selection and usage
-- 14s safety cutoff (most devices have a 10s cutoff)
-- Built-in ohm meter
-- Passthrough charging with included USB cable
It has the familiar rubberized finish that feels so good to hold, similar to most other black eGo units out there. The finish is quite sturdy, the materials are robust and the overall build quality is very solid. It comes in a very nice brown and gold display box.
If I had to pick one feature as my favorite from this feature-rich product, I think it would be passthrough. It's sooo nice to simply plug in and continue vaping when it's battery needs a charge.
And finally, based on what I've seen reported here and elsewhere online, SLB (Sailebao) is a well-renowned company. I'm not certain, but it looks like they do a combination of manufacturing and rebranding, as is done by many such companies in this still-fledgling industry.
