Overview
The Ooze Hivo is a concealer 510 battery that actually conceals. Your cartridge disappears completely inside. Flip open the lid when you want to use it, close it when you're done. Simple as that.

Design & Build Quality
The flip mechanism is what you're paying for here. Closed, the Hivo looks like some random compact gadget. Open it up, and your cartridge is right there ready to go.
Color Options
Ooze went bold with the colors: green, purple, pink, orange, blue, and black. The purple we tested looks good. Not subtle, but that's kind of the point with Ooze.
Flip-Top Mechanism
The lid does its job. It hides everything, protects your cartridge from getting banged up, and keeps pocket lint out of the mouthpiece. When closed, nobody can tell what it is.
Features
Full Concealment
Close the lid and your cartridge is gone. Invisible. Protected. The whole thing just looks like a small plastic case. You could leave it on a desk and nobody would think twice about it.
Variable Voltage
You get three voltage settings. Low works best for flavor and thin oils. Medium handles everyday use. High is for thick concentrates when you want bigger clouds.
| Setting | Best For |
|---|---|
| Low | Flavor, thin oils |
| Medium | Standard use |
| High | Thick oils, vapor |
Compact Size
It fits in any pocket without creating a weird bulge. Light enough that you forget it's there.
Performance
Protection Benefits
This is where the flip-top earns its keep. No more pocket lint clogging your mouthpiece. No more worrying about your cartridge getting knocked around. It stays clean and protected in there.
Battery Life
400mAh is on the smaller side. You'll get 100-150 puffs before needing a charge. Light users can stretch it to 2 days. If you're using it throughout the day, plan on charging every night.
Vapor Production
It's a standard 510 battery. Nothing fancy, but the power delivery is consistent. You get what you expect.
The Concealer Advantage
vs. Standard Batteries
| Aspect | Hivo | Regular 510 |
|---|---|---|
| Visibility | Hidden | Exposed |
| Protection | Flip-top | None |
| Discretion | Maximum | Minimal |
| Size | Compact | Varies |
Who Values Concealment
People who don't want their cartridge on display. Maybe you're in a professional setting. Maybe you just prefer keeping things private. Or maybe you've had too many cartridges get damaged in your pocket. The Hivo solves all of that.
Usage
Basic Operation
Pop open the lid, click the button 5 times to power on, pick your voltage, and you're set. Press the button while you inhale. Close the lid when you're done.
Cartridge Compatibility
Standard 510 cartridges fit fine. Most common sizes work. The catch is the internal cavity. Oversized or chunky cartridges might not fit. Check your cartridge dimensions before buying if you use anything unusual.
Color Personality
Six colors means you can pick something that fits your style. Go loud with pink or orange, or keep it low-key with black. Either way, when it's closed, only you know what's inside.
Maintenance
Keep the hinge clean so it keeps opening smoothly. Wipe out the cavity now and then. Clean the 510 connection if you're getting weak hits. Basic stuff that takes 30 seconds.
Who Should Buy
Ideal For
If you want discretion, the Hivo delivers. Same goes for people tired of damaged cartridges, anyone who likes fun colors, or budget-minded buyers who don't want to spend $50+ on a battery.
May Prefer Open Design If
You take a lot of hits throughout the day. That flip-top gets old fast when you're opening and closing it constantly. Same if you use big cartridges or just want something you can grab and go without the extra step.
Pros & Cons
Pros:
- Complete cartridge hiding
- Flip-top protection
- Fun colors
- Affordable
- Compact
Cons:
- Must open to use
- Limited battery
- Cartridge size limits
Verdict
The Hivo does exactly what Ooze designed it to do. It hides your cartridge, protects it, and comes in colors that are actually fun. The tradeoff is a smaller battery and that extra step of opening the lid every time. For $25, that's a fair deal if discretion matters to you.
