The crystal accents give it some visual flair, and the practical features make it solid for daily use. If you want more than a basic battery but don't want to pay premium prices, the Elf Crystal fits that gap well.
Design & Build Quality
The Elf Crystal takes the standard pen-style shape and adds decorative crystal accents that catch the light. Not everyone's thing, but if you like a bit of sparkle, it stands out from the usual plain black batteries.
HoneyStick offers seven two-tone color combos. You can go understated with Black or bold with Red-Yellow or Blue-Green. All of them have the same crystal accenting.
Build quality feels solid. Good weight without being heavy. The 510 threading is precise, and cartridges screw in without any issues.
The Digital Display
The standout feature is the small digital display showing two things:
- Current voltage setting - Know exactly what power level you're using
- Battery percentage - No more guessing how much charge you have left
This beats LED-only batteries where you have to interpret colored lights. You just look at the screen and get the info. Once you have exact numbers, going back to blinking lights feels like a downgrade.
Features
Four Voltage Settings
The Elf Crystal has four power levels:
- 2.5V - Gentlest setting for thin oils and maximum flavor
- 3.0V - Light vapor with terpene preservation
- 3.5V - Balanced everyday setting
- 4.0V - Maximum vapor for thick concentrates
The display shows your current voltage. Easy to remember your preferred setting between sessions.
12-Second Preheat Mode
Double-click to start preheat. It runs at 1.8V for 12 seconds. This low-temperature cycle warms thick oils without risking combustion, so you get smooth first draws even with viscous concentrates.
The display shows when preheat is active. No guessing.
650mAh Battery
Bigger than most batteries in this price range. At 650mAh, the Elf Crystal can handle 1-2 days of moderate use on a single charge.
The digital display shows exact battery percentage, so you can plan charging around your schedule instead of getting surprised by a dead battery mid-session.
USB-C Charging
USB-C charging is fast. Cable comes in the box. Full charges take 60-90 minutes, and the display shows charging progress.
Performance
In 10 days of testing, the Elf Crystal performed reliably across 8 different cartridges. The voltage settings make a real difference in vapor and flavor:
At 2.5V and 3.0V, flavor clarity is excellent. These settings work well with live resin and full-spectrum carts where you want to preserve terpenes.
3.5V is the sweet spot for most users and most carts. Set it and forget it.
At 4.0V, vapor production jumps up. Good for thick distillates or when you need maximum effect fast.
The preheat function does exactly what it should. Gently warms oils for smoother initial draws. We found it useful on cold mornings and with carts that had been sitting around.
Battery Life
The 650mAh capacity delivers solid longevity. In our testing:
- Light users (5-10 puffs/day): 3-4 days between charges
- Moderate users (15-25 puffs/day): 1-2 days between charges
- Heavy users (30+ puffs/day): Full day of use
The battery percentage display takes the guesswork out. When you see 20%, plug it in.
Who Should Buy This?
The Elf Crystal 510 Battery works well for:
- Value seekers who want premium features at budget prices
- Data-driven vapers who like precise voltage and battery readings
- Style-conscious users who dig the crystal look
- Heavy users who need the 650mAh capacity
- Anyone tired of guessing battery levels on LED-only devices
It's probably not for:
- Minimalists who prefer plain, simple designs
- Users who want the smallest possible device
- Those who prefer concealer-style batteries
The Bottom Line
The HoneyStick Elf Crystal 510 Battery punches above its $14.95 price tag. The digital display alone justifies the cost. Add the 650mAh battery, four voltage settings, and preheat function, and you have a device that competes with options twice the price.
The crystal design adds personality, build quality feels solid, and the feature set covers what most vapers need. If you're shopping for a 510 battery under $20, the Elf Crystal should be at the top of your list.
