Is The Tasteflex Ultralock 50K Any Good?
The disposable vape market is packed to the brim with gimmicks, but every now and then, something genuinely interesting comes along.
The Tasteflex Ultralock 50K is exactly that: a disposable vape that doesnβt just rely on high puff counts or slick packaging.
Instead, it brings something new to the table: a freakin’ motorized auto-wicking system.
Itβs not the sleekest device out there, but if youβre in the market for a high-capacity, leak-resistant vape with solid flavor and longevity, this oneβs worth a closer look.
What Is It?

The Tasteflex Ultralock 50K is a high-puff disposable vape rated for up to 50,000 puffs in its Smooth mode.
That drops to about 25,000 if youβre running it mostly in Boost mode which gives you a stronger hit and denser vapor.
Itβs built for MTL vaping and features a clear tank, dual power modes, and a 900mAh rechargeable battery (which is about par for the course, size-wise, these days).
You also get a pretty unique feature: a tiny internal motor that auto-feeds e-liquid to the coil. You can actually hear and feel it working when you vape.
Performance and Experience
This thing delivers solid flavor; it’s clean, consistent, and free from that muted, plasticky taste you sometimes get with lower-end disposables.
Boost mode gives you a nice warm draw and thick vapor, while Smooth mode dials things back to save battery and e-liquid.
The standout feature, though, is the auto-wicking system. Itβs not just a gimmick. It actually works. Reviewers noted fewer dry hits, even when the battery was nearly dead.
The way it keeps the coil isolated from the juice when youβre not using it also seems to prevent leaking. Over multiple weeks of use, some testers reported zero leaks.
As for airflow, itβs a mixed bag.
There is some adjustability, but donβt expect fine-tuning. It swings between a very airy MTL draw to something closer to a loose MTL.
If you like your draw tightβlike an old-school cigarette pullβthis probably wonβt cut it. My advise? Go for the Vaporesso XROS Pro 2; it’s refillable too, so it’ll save you a bunch of cash.
Charging is another sore spot. The batteryβs 900mAh capacity isnβt bad, but with only 1A charging, it takes longer than youβd expect to top it back up.
If you chain vape, be ready to plug in more often than youβd like.
Flavors
Hereβs how the Tasteflex Ultralock 50K flavors shook out for me after testing a handful:
- The berry blendsβespecially the mixed berry and blueberry iceβare easily the standouts. Theyβre clean, punchy, and deliver that sweet-icy hit without tasting like you’re sucking on a melted Slurpee. If you like fruity vapes with a cold edge, these are solid.
- Mint and menthol-heavy options also land well. Theyβre strong enough to give you that cooling hit but smooth enough not to feel overpowering. Good all-day vapes if you’re into that fresh, icy vibe.
- The coffee flavor was a surprise; it wasnβt bad, justβ¦ weird. Kind of like a sweetened espresso with a cooling aftertaste. Not my thing personally, but I could see someone who likes dessert vapes giving it a go.
- Watermelon Lime falls into the βmidβ category. Itβs not sweet, which is refreshing, but itβs also kind of flat. It tries to do something differentβand I respect thatβbut it didnβt hit the same way as the berry or mint flavors.
- As for the tobacco option, itβs fine. Nothing offensive, but also nothing memorable. If youβre switching from cigarettes and just want something basic, itβll do the job.
So if youβre picking a first flavor, Iβd start with the berry mixes or mint. Skip Watermelon Lime unless you like less-sweet vapes with a twist, and treat the coffee and tobacco as niche picks.
Battery and Longevity
When I stuck to Smooth mode, I easily got 2 to 3 full days of use before a top-up was required, and I vape pretty consistently throughout the day.
If youβre more of a casual user, you could probably stretch that to 4-5 days (possibly).
Switching to Boost mode cut that down to about 1-2 days, maybe three days tops, but the flavor and vapor production definitely ramped up.
It felt more like using a pod system than a disposable, which was a nice change.
What really makes this thing more user-friendly than most is the clear tank. I could see exactly how much e-liquid I had left at any point, no guesswork or dry hits.
It’s a small detail, but it makes a big difference, especially compared to other disposables where you’re flying blind.
Final Verdict

The Tasteflex Ultralock 50K actually tries something different, and mostly pulls it off.
The motorized auto-wicking sounds like a gimmick, but it improves the experience in a real, noticeable way. No dry hits, no leaking, and a smooth vape every time.
But itβs not perfect. The airflow is limited, recharging is slow, and thereβs only one nicotine strength: 5%. Thatβll be too much for some users, especially if you’re used to 3% or lower.
Still, if you’re a heavy vaper looking for a longer-lasting disposable with solid flavor and fewer issues, I’d definitely give this one a whirl even if it’s just to check out that motor-driven component inside it.
