This is the complete operation manual for every Lost Angel vape — the Mate 50K, Sphere 35K, and Pro Max 20K. First-time setup, screen indicators, mode switching, airflow adjustment, charging, pod swapping, and troubleshooting — all in one page. Whether you just unboxed your device or you're dealing with an issue, start here.
Before Your First Puff — Unboxing Steps
Every Lost Angel device needs these steps completed before first use. Skipping them is the #1 cause of "device not hitting" complaints.
| Step | Mate 50K | Sphere 35K | Pro Max 20K |
|---|---|---|---|
| 1. Remove mouthpiece plug | Pull off silicone cap on pod | Pull off silicone cap | Pull off silicone cap |
| 2. Remove insulating strip | Pull tab from pod bottom contacts | Pull tab from device bottom | Pull tab from device bottom |
| 3. Connect components | Press pod onto battery (magnets align) | N/A — one-piece device | N/A — one-piece device |
| 4. Wait for coil saturation | 30–60 seconds | 30–60 seconds | 30–60 seconds |
| 5. Take first puff | Inhale — draw activated | Inhale — draw activated | Inhale — draw activated |
Critical for Mate 50K users: The insulating strip sits between the pod and battery contacts. If you don't remove it, the battery can't power the pod. You'll drain the pod's tiny 200mAh backup battery fast, and the screen won't activate. This is the single most common setup mistake.
How to Turn On Lost Angel Vapes
All Lost Angel devices are draw-activated — there is no power button or on/off switch. Just inhale through the mouthpiece, and the device fires automatically. The screen lights up during each puff and stays illuminated for a few seconds after.
For the Mate 50K specifically: the device activates when a pod is connected to the battery. Removing the pod puts it in standby. There is no "off" mode — the battery simply sits idle when no pod is attached, using negligible power.
Understanding the Screen
Each Lost Angel device has a screen that shows real-time status. Here's what each indicator means:
Mate 50K — 3D Curved Smart Screen
| Indicator | What It Shows | Action Needed |
|---|---|---|
| Battery % | Main battery charge level (0–100%) | Charge via USB-C when below 15% |
| E-Liquid Bar | Remaining juice in current pod | Replace pod when bar is near empty |
| Puff Counter | Total puffs on current pod | Resets automatically with new pod |
| Mode Indicator | Normal or Boost | Press side button to toggle |
Sphere 35K — 270° Curved Wraparound Display
| Indicator | What It Shows | Action Needed |
|---|---|---|
| Battery Level | Remaining charge | Charge via USB-C when low |
| E-Liquid Level | Remaining juice | Device is finished when empty |
| Mode Indicator | Standard or Pulse | Toggle via device button |
Pro Max 20K
The Pro Max 20K (standard version) has a basic screen showing battery and e-liquid status. The Pro Max Touch variant adds a dual-screen setup and coil-switch functionality — press the button to toggle between coils for a slightly different flavor profile.
Mode Switching — Normal, Boost & Pulse
Lost Angel devices offer power modes that change vapor production, flavor intensity, and pod longevity. Switching is a single button press on the side of the device.
| Device | Mode 1 | Mode 2 | How to Switch |
|---|---|---|---|
| Mate 50K | Normal (~50K puffs, cooler vapor) | Boost (~30K puffs, warmer/denser) | Press side button once |
| Sphere 35K | Standard (full puff life) | Pulse (intermittent power bursts) | Press device button once |
| Pro Max 20K Touch | Coil A | Coil B (different flavor character) | Press button once |
When to use each mode:
Normal/Standard Mode — Your daily default. Maximizes pod life and battery efficiency. Best for menthol and ice flavors where the cooler temperature keeps the cooling sensation crisp.
Boost Mode (Mate 50K) — Use when you want bolder flavor, warmer vapor, or a stronger throat hit. Especially good for dessert flavors (Frappe, Strawberry Shortcake) and fruit flavors (Tropical Boom, Berry Bliss). Burns juice ~40% faster than Normal.
Pulse Mode (Sphere 35K) — Delivers intermittent higher-power bursts during your draw. Creates vapor "pulses" that intensify throat hit without running at high power constantly. Pairs exceptionally well with menthol flavors like Alaskan Mint and Miami Mint.
Airflow Adjustment
The Mate 50K and Sphere 35K both feature adjustable airflow controls. The Pro Max 20K has fixed airflow.
Mate 50K: Rotate the dial on the bottom of the battery unit. Left = tighter (MTL), right = more open (RDL). The dial has smooth, continuous adjustment — no clicks or detents.
Sphere 35K: Adjustable airflow ring on the device body. Same principle — tighter for a cigarette-like draw, more open for bigger clouds.
| Airflow Setting | Draw Feel | Best For |
|---|---|---|
| Tight (closed) | Restricted, firm pull — like a cigarette | MTL vaping, strong throat hit, former smokers |
| Medium | Balanced draw, moderate resistance | Most users — start here and adjust |
| Open (fully open) | Smooth, airy pull — minimal resistance | DTL vaping, bigger clouds, smooth experience |
Airflow setting does not affect e-liquid consumption or pod life — only the feel and cloud size. Adjust freely.
How to Charge Lost Angel Vapes
All Lost Angel devices charge via USB Type-C. No cable is included — use any USB-C cable you already have.
| Device | Battery | Charge Time (Low → Full) | Usage Between Charges |
|---|---|---|---|
| Mate 50K | 1,200mAh (detachable) | ~45–55 minutes | 1.5–2 days at ~500 puffs/day |
| Sphere 35K | Built-in (capacity undisclosed) | ~35–45 minutes | 1–1.5 days at ~500 puffs/day |
| Pro Max 20K | Built-in | ~30–40 minutes | 1–1.5 days at ~500 puffs/day |
Charging tips:
Charge before the battery drops below 10% — very low battery causes weak vapor and muted flavor. All Lost Angel devices support pass-through charging (you can vape while plugged in), but this generates extra heat and isn't ideal for long-term battery health. Unplug when full — don't leave devices charging overnight.
How to Swap Pods (Mate 50K Only)
The Mate 50K is the only Lost Angel device with swappable pods. The Sphere 35K and Pro Max 20K are sealed, all-in-one devices.
1. Pull current pod straight up. Don't twist — just pull. Magnets release cleanly.
2. Prepare new pod. Remove mouthpiece plug + insulating strip (new pods only). If rotating a partially used pod back in, just wipe the contacts.
3. Press new pod onto battery. Magnets snap it into place with an audible click. Display activates immediately.
4. Wait 30 seconds before first puff on a new pod. This prevents dry hits.

When to Replace Your Device or Pod
| Device | Replace When | Signs |
|---|---|---|
| Mate 50K Pod | E-liquid is depleted | E-liquid window empty, flavor thins out, puff count near 40K+ (Normal) or 25K+ (Boost) |
| Mate 50K Battery | Battery no longer holds charge | Extremely rare — most batteries last through many pods. If charge drops unusually fast, battery may need replacing. |
| Sphere 35K | E-liquid or battery is depleted | Flavor declines, vapor production drops, screen shows empty |
| Pro Max 20K | E-liquid or battery is depleted | Same as Sphere 35K |
Don't push past empty. Vaping on a dry coil produces a burnt taste that's unpleasant and potentially harmful. When flavor starts declining, stop and replace.
Troubleshooting — All Devices
Device not hitting / no vapor
Check first: Did you remove the insulating strip? This is the #1 cause. Also verify the mouthpiece plug is removed. For Mate 50K, ensure the pod is fully seated (push down until you hear a click). Check battery level — if it's completely dead, charge for at least 10 minutes before trying again.
Weak or thin vapor
Low battery is the most common cause — charge the device. If the battery is fine, check airflow (too tight = restricted output). Try switching to Boost Mode (Mate 50K) or Pulse Mode (Sphere 35K) for stronger hits. If all else fails, the pod/device may be near-empty.
Burnt or cotton taste
The e-liquid is running low. Check the liquid window and puff counter. If it's a brand-new pod/device, you didn't wait long enough for the coil to saturate — stop vaping, wait 2 minutes, then try a slow, gentle draw.
Not charging
Try a different USB-C cable — low-quality cables are the most common cause of charging issues. Check the charging port for dust or lint (use a toothpick to gently clean it). Ensure the power source is working (try a different USB port or wall adapter).
Screen not turning on
The screen only activates during a puff or for a few seconds after. If it's completely dark, the battery is likely fully dead — charge for 5-10 minutes and try again. For the Mate 50K, verify the pod is properly connected.
Leaking
Minor condensation around the mouthpiece or pod contacts is normal, especially in humid conditions. Wipe with a dry cloth. If actual e-liquid is leaking, store the device upright (mouthpiece up). Avoid extreme temperatures — heat causes e-liquid to thin and leak.
Mate 50K: Battery and pod "out of sync"
Occurs after extended standalone pod use (without the main battery). Fix: reconnect pod and battery, leave connected for 10–15 minutes without vaping. They'll resync automatically.

Frequently Asked Questions
How do I turn on my Lost Angel vape?
All Lost Angel devices are draw-activated. There's no power button or on/off switch — just inhale to activate. Make sure you've removed the mouthpiece plug and insulating strip first.
How long does a Lost Angel vape last?
The Mate 50K delivers up to 50,000 puffs per pod (Normal Mode). The Sphere 35K lasts up to 35,000 puffs. The Pro Max 20K delivers 20,000 puffs. At moderate daily use (~500 puffs/day), that's roughly 3+ months for the Mate 50K, 10 weeks for the Sphere 35K, and 6 weeks for the Pro Max 20K.
Can I use the Mate 50K pod without the battery?
Yes, briefly. Each pod has a 200mAh built-in battery for light draw-activated use. But the screen, mode switching, and recharging all require the main 1,200mAh battery. Use standalone mode only in emergencies.
What does Pulse Mode do on the Sphere 35K?
Pulse Mode delivers intermittent bursts of higher power during your draw, creating vapor intensity spikes. It produces a stronger throat hit without constantly running at high wattage. It's most effective with menthol and ice flavors.
Is there a way to reset my Lost Angel vape?
Lost Angel devices don't have a traditional reset function. If your device isn't working, try: (1) clean the charging port and contacts, (2) charge fully, (3) for Mate 50K, remove and reattach the pod. If the e-liquid is depleted, no reset will restore performance — you need a new pod or device.
