Pulsar 510 DL Vape Pen Review: 2.0 vs. 5.0 vs. 6.0

The Pulsar 510 DL has grown into a full lineup, and searchers are increasingly looking for a specific version rather than the pen in general. If you've searched "pulsar 510 dl," there's a good chance that what you actually want to know is how the 2.0, 5.0, and 6.0 compare, so here's a version-by-version breakdown to help you pick the right one.

Which Pulsar 510 DL Should You Buy? (2.0 vs. 5.0 vs. 6.0)

All three versions share the same core idea: a stealthy, breath-activated 510-thread battery disguised as a disposable vape. Where they differ is battery size, display, and control options.

The original 300mAh 510 DL is still the most pocket-discreet of the lineup, but all three newer versions above it share a 1000mAh battery, so the real differences come down to display, voltage precision, and how much control you want over the draw.

Pulsar 510 DL 5.0 Review

The 510 DL 5.0 keeps the same disposable-look design the lineup is known for, but swaps the earlier LED display for a full LCD screen with a light bar down the side, giving you a clearer read on battery life and voltage at a glance.

• Battery: 1000mAh, a meaningful step up from the original 300mAh version and matching the 2.0 Pro.
• Voltage range: 1.8V to 4.2V in 0.1V increments, noticeably finer control than the 2.0 Pro's five fixed settings.
• Cartridge size: Built to accommodate larger 2g carts, not just the smaller 1mL to 2mL sizes the earlier versions were designed around.
• Control: Auto-draw activation by default, with a tactile button available if you'd rather set voltage manually instead of cycling through puffs.

For anyone who found the 2.0 Pro's five preset voltages a bit limiting, the 5.0's fine-grained voltage control is the clearest upgrade. The tradeoff is a slightly larger body than the most discreet pen-style options, though it still keeps the disposable-vape look that defines the line.

Pulsar 510 DL 2.0 Review

The 510 DL 2.0 Pro is the version Grasscity currently carries, including a Grateful Dead collaboration model, and it's the workhorse of the lineup for anyone who wants real features without stepping up to the 5.0 or 6.0's price point.

• Battery: 1000mAh, up from the original 510 DL's 300mAh, with USB-C charging.
• Voltage range: Five settings between 2.4V and 3.8V, including lower-temperature options aimed at preserving flavor on distillate carts.
• Display: A side-mounted digital display shows battery level, voltage setting, and a built-in puff counter.
• Extras: A 15-second pre-heat function at 1.8V primes thicker oils, haptic feedback confirms voltage changes and connections, and auto standby after 10 seconds along with short-circuit protection add a layer of safety most budget batteries skip.
• Cartridge fit: Accommodates carts up to 14.5mm by 60mm, wider than the original DL's more limited fit.

This is the version with the strongest direct review-intent search demand right now, and it's easy to see why: it hits a real middle ground of features (display, puff counter, pre-heat, haptic feedback) without the premium pricing of the newer versions.

Pulsar 510 DL 6.0 Review

The 510 DL 6.0 is the newest version in the lineup, and it trades some of the earlier models' extreme discretion for a much more prominent display and added control.

• Battery: 1000mAh, in line with the 2.0 Pro and 5.0.
• Display: A wraparound LCD with animated graphics, the most visually prominent screen in the lineup, though this also makes it the least disposable-looking of the three.
• Voltage range: 1.8V to 4.2V in 0.1V increments, matching the 5.0's precision.
• Airflow: Adjustable airflow is new to this version, letting you fine-tune draw resistance rather than relying on a fixed airpath.
• Pre-heat: An 8-second pre-heat function, faster than the 2.0 Pro's 15-second cycle.
• Cartridge fit: Built for carts up to 3g, the largest capacity in the lineup.

The 6.0 is the version to watch if you want the most control and don't mind a slightly bulkier, more attention-grabbing device in exchange for it. Search interest is still small compared to the 2.0 and 5.0, but it's grown quickly enough that it's worth covering now rather than waiting for demand to catch up to the content.

Battery Life and Performance

Across the lineup, battery capacity is the single biggest factor in real-world performance.

• 300mAh (original 510 DL): The most discreet and pocket-friendly option, but light users will still likely need to recharge more than once a day with regular use.
• 1000mAh (2.0 Pro, 5.0, 6.0): All three newer versions share this capacity, which comfortably covers a full day of moderate use for most people, roughly in line with the 200-puffs-per-charge range typical of batteries in this size class.
• Voltage range affects battery drain too. Higher voltage settings draw more power per puff, so someone running the 5.0 or 6.0 at the top of their voltage range will see faster battery drain than someone using lower settings on the 2.0 Pro.
• None of the three newer versions offer pass-through charging, meaning you can't use the device while it's charging, a limitation worth knowing about if you're relying on it throughout a full day.

Battery size aside, actual performance also comes down to matching voltage to your cartridge. Thicker oils generally need higher voltage and benefit from the pre-heat function on any of these versions, while thinner distillate oils tend to taste better at the lower end of each device's voltage range.

Bottom Line

The right Pulsar 510 DL comes down to how much you value discretion versus control. The original 300mAh pen is still the most pocket-friendly option for light, casual use. The 2.0 Pro is the practical middle ground, real features at a reasonable price, and it's what Grasscity currently stocks.

The 5.0 and 6.0 push further into fine-grained voltage control and larger cartridge support, with the 6.0 trading some of the line's signature stealth for its most capable display and airflow control yet.
