Introduction
Not everyone needs a feature-packed box mod. Sometimes you want a simple, reliable 510 battery that works well and does not cost much. The Wulf Mods Grid targets exactly this need—a budget-friendly option that does not sacrifice essential features.
At under $20, the Grid competes with disposable-tier pricing while offering rechargeable convenience, variable voltage, and a 650mAh battery that punches above its price class. Available in 10 colorful finishes, it adds personality without adding cost.
Design and Build
The Grid uses a compact rectangular form factor that is both pocketable and comfortable to hold. At 2.5 inches long, it is smaller than box mods while providing more battery than pen-style alternatives.
The standout design feature is the built-in keyring loop. This small addition makes the Grid genuinely portable—attach it to your keys, bag, or lanyard for grab-and-go convenience. Many competing batteries overlook this simple but useful touch.
Build quality is solid for the price. The body is durable plastic available in spatter finishes, solid colors, and multi-color options. While not premium, it feels sturdy and handles daily use well.
LED Display
A small LED screen shows:
- Boot-up and shutdown animations
- Current voltage setting (via color)
- Battery level indication
The display adds visual feedback without the complexity of full digital screens.
What's in the Box
- Wulf Mods Grid battery
- USB-C charging cable
Simple packaging matches the simple, focused design philosophy.
Voltage Settings
Four preset voltages cover the useful range:
| Setting | Voltage | LED Color | Best For |
|---|---|---|---|
| 1 | 2.8V | Green | Thin oils, maximum flavor |
| 2 | 3.2V | Yellow | Standard cartridges |
| 3 | 3.6V | Purple | Thicker oils, more vapor |
| 4 | 4.0V | Pink | Very thick concentrates |
Changing Voltage
Click the button 3 times to cycle through settings. The LED color indicates your selection. The device remembers your setting when powered off.
Fixed vs. Adjustable
Unlike the UNI 3.0's 0.1V increments, the Grid uses fixed presets. This simplifies operation—just cycle to your preferred color and go. Most users find four options sufficient for optimizing their cartridges.
Button Functions
| Action | Function |
|---|---|
| 5 clicks | Power on/off |
| 3 clicks | Cycle voltage settings |
| 2 clicks | Preheat (12 seconds) |
| Hold | Fire/heat cartridge |
The interface is straightforward with no complex menus to navigate.
Performance
Cartridge Compatibility
The Grid uses standard 510 threading without the adjustable fit of the UNI series. This means:
- Standard-width cartridges: Excellent fit
- Slim pen cartridges: Good fit
- Wide tanks: May not sit flush
- Tall cartridges: Work fine, extend above the body
Most common 510 cartridges work well. Users with unusual cartridge sizes should consider the UNI 3.0 instead.
Vapor Production
Performance varies by voltage and cartridge:
- 2.8V (Green): Light vapor, maximum flavor preservation
- 3.2V (Yellow): Balanced—good for most cartridges
- 3.6V (Purple): Noticeable vapor increase
- 4.0V (Pink): Maximum vapor, may reduce flavor
The 650mAh battery provides consistent power delivery throughout its charge cycle.
Preheat Function
Double-click for a 12-second preheat cycle. This feature:
- Warms thick oils before drawing
- Improves first hits with viscous concentrates
- Helps in cold weather
- Primes new cartridges
15-Second Timeout
The Grid automatically stops after 15 seconds of continuous draw. This safety feature prevents overheating. Release and press again for extended sessions.
Battery Life
The 650mAh battery is excellent for this price tier:
- Light users: 2-3 days between charges
- Moderate users: Full day comfortably
- Heavy users: May need evening charging
USB-C charging is a welcome modern inclusion. Many budget batteries still use micro-USB. Charge time is 1-2 hours depending on your power source.
Important: The manufacturer warns against charging with power banks over 5V or charging in vehicles. Use standard USB outlets for best results.
Color Options
The Grid comes in 10 finishes:
- Black-Green Spatter
- Blue-Black Spatter
- Full Color
- Pink-Black Spatter
- Purple-Black Spatter
- And more depending on availability
The variety adds personality at no extra cost—pick a style that matches your preference.
Who Should Buy the Grid
Budget-conscious users: Under $20 for a quality 510 battery with USB-C and variable voltage is excellent value.
Simplicity seekers: Four preset voltages and basic controls mean no learning curve.
Portable users: The keyring loop and compact size suit on-the-go lifestyles.
Casual users: If you use cartridges occasionally, the Grid handles the job without overspending.
Style-conscious users: Ten color options let you express personality.
Who Should Look Elsewhere
Precise control needs: The UNI 3.0's 0.1V increments offer finer adjustment if you optimize each cartridge.
Wide cartridge users: Without adjustable width, very thick cartridges may not fit well.
Concealment priority: The exposed cartridge is visible—consider concealing box mods if discretion matters.
Heavy users: While 650mAh is good, very heavy use may want larger capacity.
Comparison to Competitors
vs. UNI 3.0
The UNI 3.0 ($35) offers adjustable fit, precise voltage control, and a digital display. The Grid ($18) is simpler with fixed presets. The Grid costs half as much for users who do not need advanced features.
vs. Cheap Gas Station Batteries
No-name batteries may cost $10-15 but often have smaller batteries, micro-USB, and questionable build quality. The Grid's 650mAh, USB-C, and Wulf Mods quality justify the slight premium.
vs. Pen-Style Batteries
Basic 510 pens are smaller but typically have smaller batteries (300-400mAh) and fewer voltage options. The Grid adds capacity and control in a still-compact form.
Final Verdict
The Wulf Mods Grid proves that budget does not mean compromise. Its 650mAh battery, four voltage settings, USB-C charging, and keyring portability deliver features typically found at higher prices. The ten color options add personality without adding cost.
The fixed voltage presets and standard 510 threading are reasonable trade-offs for the price. Users needing precise control or universal cartridge fit should step up to the UNI 3.0. For everyone else, the Grid offers genuine value that is hard to beat.
If you want a reliable, stylish 510 battery without overspending, the Grid earns its place on your keychain.
