Quick tip · before you start
Always use a 5W or higher USB-C wall adapter. Charging from a low-output (2.5W) laptop port works but doubles the time and can confuse the LCD gauge into showing inaccurate percentages until you cycle the device.
Choose the right USB-C cable for your Dojo Vape
Every Dojo device — iMate X 20K hub, Sphere S 40K, PUREX 60K — uses a standard USB-C input port. No proprietary cable, no oddball connector. The recommended cable specification is USB-C male to USB-A male, with a conductor gauge of 24 AWG or thicker and a length of 1 to 2 feet. Longer cables (6 ft+) introduce voltage drop that slows the charge and can confuse the hub's percentage gauge into reading inaccurate state-of-charge during the first 10 minutes of a recharge. Avoid thin no-name cables sold in bulk at gas stations or convenience stores — they often run 28 AWG conductors that bottleneck current and overheat under load. If a cable feels warm to the touch anywhere along its length during a Dojo charge cycle, replace it immediately; that's the cable working harder than its rating allows.
Charging the Dojo iMate X 20K hub — time, port location, behavior
The iMate X hub's USB-C port is recessed into the bottom edge of the chassis, opposite the magnetic pod dock. Plug in the cable and the side LED illuminates to a slow green pulse while the HD LCD displays a battery-fill animation across the screen, refreshing roughly once per second. Full charge from a hard 0% takes approximately 1.5 hours at 5W input (5V / 1A). Charging proceeds along a standard CC-CV (constant current / constant voltage) profile typical of lithium-ion cells, which means the last 10% takes proportionally longer than the first 50% — this is normal cell chemistry, not a defect. When charging completes, the LCD switches to a green check mark and the side LED settles to a steady green for several minutes before going dark. The hub does not over-charge once full; the chip detaches the cell from the input rail.
How the iMate X pod charges through the hub via the magnetic dock
The iMate X pod has no USB-C port of its own. It charges exclusively through the magnetic dock on the hub, drawing current through the gold-plated contact pins when both the hub is plugged in and the pod is properly seated. This is a deliberate Vaporesso engineering decision: the pod is meant to be docked the vast majority of its life, so adding a USB-C to the pod itself would have increased the pod's bill of materials without delivering meaningful user benefit. If you're using the pod in standalone mode (popped off the hub), you cannot recharge it independently — the pod is draw-activated and runs through its rated 20,000 puffs (12,000–16,000 in real-world use) across whatever residual charge was in the pod's 400 mAh internal cell at the moment of standalone use. To top up the pod, simply dock it on a charging hub for 30 minutes.
Charging the Dojo Sphere S 40K — time, port, 360° LCD behavior
Sphere S 40K's USB-C port is located on the bottom-left edge of the device, near the lanyard hole. Plug in and the 360° surround LCD displays a wrap-around charge animation visible from every angle — one of the few cases where the surround screen does something a flat front-mounted LCD couldn't. Full charge from 0% to 100% takes approximately 2 hours at 5W input. Sphere S uses a single 1100 mAh internal cell rather than the dual-cell architecture of PUREX. Sphere S supports pass-through use during charging: you can take draws while the cable is plugged in. The flavor and vapor density during pass-through charging is identical to unplugged operation because the battery management routes a sufficient share of the input current directly to the coil.
Charging the Dojo PUREX 60K — time, dual battery, pass-through priority
PUREX 60K is the most engineering-heavy device in the Dojo lineup when it comes to charging. The USB-C port sits on the bottom face. Full charge from 0% to 100% takes approximately 2.5 hours at 5W input — longer than Sphere S because PUREX's dual-cell battery architecture sums to 1500 mAh of capacity (versus Sphere S's 1100 mAh single cell). PUREX implements aggressive pass-through: the battery management chip splits the USB input current between cell recharge and coil firing, so coil performance during a pass-through draw matches unplugged operation. The ring LED on the chassis transitions through a charge-pulse pattern: red ring (0–20%), amber ring (20–80%), green ring (80–100%), then steady green at full. PUREX's dual-cell design with series-parallel balancing is also why the device maintains consistent vapor density past 40,000 puffs where single-cell 60K competitors typically taper meaningfully.
⚠ WARNING
Never charge a Dojo device overnight on a power adapter you don't trust. The chips have over-current protection but cheap (non-UL-listed) adapters can deliver irregular voltage that bypasses the protection circuit. Charge during waking hours.
First-charge calibration for an out-of-box Dojo Vape
Fresh-from-factory Dojo devices ship in a partial-charge state (typically 30–50% to comply with international shipping regulations on lithium-ion cells). Best practice for the very first use is a single calibration cycle: vape down to a hard 0% (the iMate X LED will go red blinking; Sphere S and PUREX show critical-low LED patterns), then recharge uninterrupted to a full green. This calibrates the on-device state-of-charge gauge to the actual cell capacity, which improves the accuracy of the percentage readout for the remaining life of the device. Skipping this calibration step is fine for casual use — the gauge self-calibrates over the first 2-3 normal charge cycles — but the readout can show ±10% drift in those early cycles if you don't do the deliberate first-cycle calibration. After the calibration, partial-cycle charging (recharging between 20% and 80%) is preferred for cell longevity.
Expected charge-cycle lifespan for each Dojo device
The iMate X 20K hub uses a long-cycle lithium-ion cell rated for approximately 500 full charge cycles before noticeable capacity drop (under 80% of original capacity). Since one full cycle equals roughly two pods' worth of use, you can expect about 1,000 pods through a single hub before the cell starts showing measurable wear — far longer than the typical retail vape ownership window. Sphere S 40K and PUREX 60K are sealed disposables, so the cell lifespan is matched to the juice lifespan; you won't experience charge-cycle degradation before the 40,000 / 60,000 puff count is reached because there's only enough juice in the device for roughly 80-120 full cycles. End-of-life signs for sealed devices are juice depletion (thinning vapor, flavor drop-off) rather than battery aging.
When charging no longer revives it, grab a fresh one: browse Dojo vape flavors, order from Dojo Vape, and see Dojo vape near me for shipping speed.

FAQ
Common Dojo Vape Questions
What USB-C cable should I use for my Dojo Vape?
Any USB-C cable rated for at least 5W (5V/1A) charging. We recommend USB-C to USB-A cables in the 1–2 foot range for desk use. Avoid USB-C to USB-C with a high-wattage laptop adapter (60W+) — Dojo devices internally cap at 5W and a high-wattage adapter can trigger over-current protection on some hubs.
How long does the iMate X hub take to charge?
About 1.5 hours from 0% to 100% via USB-C at 5W input. LCD shows a battery animation while charging. The hub re-charges the docked pod through the magnetic contacts as you continue using it — there's no separate pod cable.
How long does Sphere S 40K take to charge?
About 2 hours to full via USB-C. The port is on the bottom edge of the device. Sphere S supports pass-through use during charging — the LED stays on the charge-pulse pattern but vaping is uninterrupted.
How long does PUREX 60K take to charge?
About 2.5 hours to full via USB-C at 5W input. PUREX has the most aggressive pass-through implementation in the lineup — battery management splits the current so the coil keeps firing at full wattage during a recharge cycle.
What is pass-through charging on a vape?
Pass-through means the device's battery management circuit routes USB power directly to the coil while simultaneously charging the cell. You can vape while plugged in without the coil throttling. PUREX 60K and Sphere S 40K support pass-through; iMate X (hub) does too once it's at least 20% charged.
Can I use a phone wall adapter to charge my Dojo?
Yes — any phone-class USB charger (5V/1A or 5V/2A) works. Avoid 18W+ fast-charge adapters (Qualcomm Quick Charge, USB-PD), and avoid laptop adapters in the 60W+ range. The internal regulator caps charging at 5W, so faster adapters just waste their headroom or trip protections on some units.
Should I drain my Dojo to 0% before recharging?
No. Lithium-ion cells prefer partial-cycle charging (recharge anywhere between 20% and 80%). Running to 0% repeatedly accelerates capacity loss. For 40K+ devices like Sphere S and PUREX, topping up to full before bed is the best routine for cell longevity.
My Dojo Vape won't charge — what now?
Three checks: (1) try a different USB-C cable — failed cables are the #1 cause; (2) try a different adapter; (3) inspect the USB-C port for debris (a needle clears it). If all three fail and the LED never lights when plugged in, the charge circuit is dead — warranty claim with photo.
