Universal Charging Steps — Works for All Lost Mary Devices
Locate the USB-C port
The charging port is on the bottom of every current Lost Mary device. On the NERA 70K, it's on the bottom of the battery dock. On disposable models (Ultrasonic, MT35000, MO20000), it's on the base of the device.
Connect a USB-C cable
Plug a USB-C cable into the port and connect the other end to any USB power source — wall adapter, laptop, power bank, or car charger. Use a standard 5V adapter (the type that comes with most phones). Do not use high-wattage fast chargers designed for laptops (45W+).
Confirm charging has started
The device's LED or display will indicate charging is active. On the NERA 70K, the curved screen shows battery percentage climbing. On the MT35000 and MO20000, the display lights up with the battery icon. On the Ultrasonic 35K, the LED indicator glows.
Wait for full charge
Charging takes 45–90 minutes depending on the model (see table above). When fully charged, the display/LED will show 100% or change to a solid color. Disconnect the cable once fully charged — do not leave plugged in overnight.
Charging by Device — Model-Specific Notes
NERA Fullview 70K
Charge the battery dock only — pods don't have batteries. The 3D curved screen shows exact battery percentage during charging. You can vape while charging (pass-through supported). When swapping pods, no recharge needed.
800mAh · 45–60 min · USB-C on dock bottom
Ultrasonic 35K
The LED indicator changes color while charging: red (low) → blue (charging) → green (full). No percentage display — just color-based status. Make sure the Off/Normal/Boost slider is in any position except "Off" to confirm charging starts.
800mAh · 45–60 min · USB-C on device bottom
MT35000 Turbo
Largest battery in the lineup (1000mAh) = longest charge time. The blend-in display activates during charging and shows battery animation. Pass-through vaping is supported. Takes slightly longer than other models — allow 60–90 minutes for a full charge.
1000mAh · 60–90 min · USB-C on device bottom
MO20000 Pro
The Mega HD screen shows exact battery percentage during charging plus an animated charging graphic. Fastest visual feedback of any model — you can watch the percentage climb in real time. Normal charge time despite the feature-rich display.
800mAh · 45–60 min · USB-C on device bottom
How to Read Charging Indicators

|---|---|---|---|
| NERA 70K | Screen shows rising % + charging icon | Screen shows red battery icon | Screen shows 100% |
| Ultrasonic 35K | LED glows blue | LED flashes red | LED turns green |
| MT35000 Turbo | Display shows battery animation | Display shows low battery warning | Display shows full icon |
| MO20000 Pro | HD screen shows climbing % | Screen flashes low battery alert | Screen shows 100% |
Battery Tips & Best Practices
For the NERA 70K specifically: the reusable battery dock benefits from regular, shallow charge cycles rather than full drain-to-zero. Keeping the battery between 20–80% extends its long-term lifespan, just like a phone battery.
Troubleshooting — Lost Mary Won't Charge
Try a different USB-C cable
The most common cause of charging failure is a faulty cable. Try a cable you know works with another device (phone, tablet). If the new cable works, discard the old one.
Try a different power source
Switch from a wall adapter to a laptop USB port (or vice versa). Some adapters don't output enough current; others output too much. A standard phone charger (5V/2A) is ideal.
Clean the charging port
Lint, dust, or e-liquid residue can block the connection. Use a dry toothpick or compressed air to gently clean inside the USB-C port. Do not use water or metal objects.
Check for e-liquid leaks around the port
If e-liquid has leaked into the charging port, it can prevent electrical contact. Wipe the area with a dry paper towel and let it air-dry for 30 minutes before trying again.
If nothing works — the battery may be dead
All rechargeable batteries have a finite lifespan. If the device is old and won't charge with any cable or adapter after cleaning, the battery has likely reached end of life. For disposable models (Ultrasonic, MT35000, MO20000), this means the device needs to be replaced. For the NERA 70K, contact Lost Mary support about the battery dock — the pods are still usable with a new dock.
Frequently Asked Questions
Can I use my phone charger to charge a Lost Mary vape?
Yes — any USB-C phone charger works. Use a standard 5V adapter. Avoid high-wattage laptop chargers (45W+), though most modern adapters automatically adjust output and are safe. The cable that came with your phone is perfectly fine.
Can I vape while my Lost Mary is charging?
Most Lost Mary devices support pass-through charging (vaping while plugged in). The MT35000 Turbo and NERA 70K both officially support this. However, it's best practice to let the device charge fully before using it — pass-through charging generates extra heat and can reduce battery lifespan over time.
How do I know when my Lost Mary is fully charged?
On the NERA 70K and MO20000 Pro, the screen shows 100%. On the MT35000 Turbo, the display shows a full battery icon. On the Ultrasonic 35K, the LED turns green. Once fully charged, disconnect the cable.
Why is my Lost Mary blinking while charging?
A blinking LED during charging usually indicates the device is actively charging (normal behavior on the Ultrasonic 35K). If the LED blinks rapidly and stops, it may indicate a connection issue — try a different cable. If the device blinks when you try to vape and won't produce vapor, the battery is dead and needs recharging or the device has reached end of life.
How long does a Lost Mary battery last between charges?
The MT35000 Turbo (1000mAh) lasts 1.5–2 days. The NERA 70K, Ultrasonic 35K, and MO20000 Pro (all 800mAh) last 1–1.5 days. Heavy use and higher power modes drain the battery faster. See our device reviews for detailed battery performance: Lost Mary Complete Guide.
