Arizer Solo 2

Replaceable 18650 battery (3,400 mAh). Runtime is 90-120 minutes depending on temperature — roughly 15-20 sessions at 5 minutes each.

Spare cells cost under €10 and swap easily: unscrew the bottom cap, pull out the battery. Pass-through charging via Micro-USB works.

The Solo 2 MAX offers the same core performance with USB-C and longer runtime (~3 hours). If you already own a Solo 2 and are happy, no need to upgrade.

Battery Tips for Maximum Lifespan

• Don't store at 100% constantly: 18650 cells last longer when stored between 20% and 80%.
• Rotate spare batteries: Using two batteries in rotation extends the overall lifespan of both.
• Use passthrough sparingly: Charging during use stresses the battery more than normal charging.
• Original battery: Arizer recommends the included 18650 — cheap no-name cells may reduce performance.

Charging Times Overview

Two aroma tubes included: standard (straight) and frosted (cools slightly more, fits more snugly). Both borosilicate glass, both compatible with water pipe adapters (14 mm / 18 mm sold separately).

Stainless steel dosing capsules are available and keep the chamber clean. Without capsules: 0.15-0.2 g. With capsule: about 0.1 g.

The stems protrude from the top — making the Solo 2 less pocket-friendly than the ArGo, but the longer vapor path delivers cooler draws.

Stem Types Compared

Cleaning the Glass Stems

Isopropyl alcohol (90%+) and a zip bag are all you need: place the stem inside, wait 30 minutes, rinse with hot water. Stubborn residue also dissolves when simmered in milk (the fats bind the resin). Clean the chamber in the device itself with the included brush — never put alcohol into the device.

LED display with current and target temperature. Two-button controls: up and down. Up to 10 programmable session presets for different temperatures.

Auto shut-off after adjustable time (default: 15 minutes). No Bluetooth, no app — Arizer keeps it deliberately simple. For more control, look at the Solo 3 V2 with color display and on-demand mode.

Session Workflow in Practice

1. Fill the stem: 0.15–0.2 g medium grind, loosely packed. Don't tamp down.
2. Power on: Press button 5×. Display shows heat-up phase (~30 s).
3. Inhale: Slow, steady draws over 5–10 seconds.
4. Increase temperature: After 3–5 draws, raise by 5–10 °C for more extraction.
5. End session: Device auto-shuts off after 15 min, or press 5× manually.

Setting Up Presets Effectively

The Solo 2 stores up to 10 temperature presets. In practice, 3–4 are enough:

• Preset 1 (Flavor): 180 °C — first draws of a fresh fill
• Preset 2 (Standard): 195 °C — everyday setting for most users
• Preset 3 (Intense): 210 °C — last draws or denser clouds

The MAX is an upgrade, not a redesign:

If you do not own a Solo yet and budget allows, get the MAX. If the Solo 2 is within your budget: go for it — vapor quality is identical.

Hybrid heating with ceramic element: conduction through chamber walls plus convection through the herb bed. 50-220°C in 1-degree steps, heat-up in about 35 seconds.

The glass airpath remains Arizer's strength: borosilicate aroma tubes, no plastic in the vapor path. Flavor is clean and unaltered — especially at lower temperatures between 175 and 195°C where the full aroma profile shines.

Temperature Guide: Effects per Level

Improvements Over the Solo 2

The Solo 2 MAX heats up in about 25 seconds — roughly 5 seconds faster than its predecessor. The improved hybrid heating delivers more even convection while maintaining the same glass airpath purity. If you already own a Solo 2 and are happy with its performance, the MAX mainly adds comfort improvements: faster charging, longer runtime, and a more modern display.

Two aroma tubes included: standard and frosted. Both borosilicate glass, both fit water pipe adapters (14 mm and 18 mm sold separately).

Stainless steel dosing capsules included. They hold about 0.1 g and keep the chamber clean — practical for travel. Without capsules, the chamber fits 0.15-0.2 g.

Cleaning: soak aroma tube in isopropyl alcohol (90%+), brush out the chamber. Glass parts can be boiled in hot water.

Stem Compatibility

All Solo 2 glass stems fit the Solo 2 MAX — existing accessory collections carry over completely.

Dosing Capsules: Clean and Efficient

Stainless steel dosing capsules keep the chamber clean and allow micro-dosing at ~0.1 g. For travel: pre-fill capsules, carry them in the included container, and simply insert at your destination. The chamber stays nearly residue-free — weekly cleaning then focuses only on the stems.

LED display showing current and target temperature, battery level, and session timer. Controls via buttons on the device: temperature up/down, start session, save presets.

Up to 10 programmable session presets for different temperatures and durations. Auto shut-off after adjustable time (default: 15 minutes). No app, no Bluetooth.

Session Workflow with Timer

1. Fill the stem: 0.15–0.2 g medium grind, loosely packed.
2. Power on: Press button 5×. OLED shows heat-up phase (~25 s).
3. Set timer: Choose session duration between 5 and 15 minutes.
4. Inhale: Slow draws, haptic feedback confirms operation.
5. Increase temperature: After 3–5 draws, raise by 5–10 °C.

Setting Up Presets

The Solo 2 MAX offers 5 preset slots. Recommended configuration:

• Preset 1: 180 °C — Flavor, first draws
• Preset 2: 195 °C — Everyday session
• Preset 3: 210 °C — Intense, last draws
• Preset 4: 220 °C — Maximum, full extraction

An upgrade, not a redesign:

If you do not own a Solo yet, get the MAX. If you already have a Solo 2 and are happy with it, no need to upgrade — the core performance is identical.

Regular cleaning keeps the Solo 2 MAX performing at its best and ensures pure flavor. Brush out the chamber after every session to remove loose residue. Clean the mouthpiece and vapor path weekly with isopropyl alcohol (90% or higher).

Cleaning Schedule

Common Mistakes to Avoid

• Never use water inside the chamber — only isopropyl or dry cleaning
• Do not use sharp metal tools in the vapor path
• Replace screens when draw resistance increases

Choosing the right temperature on the Solo 2 MAX determines flavor, vapor density, and active compound profile. Lower temperatures (170–185 °C) emphasize terpenes and deliver mild, aromatic vapor. Higher temperatures (195–210 °C) produce thicker clouds and stronger effects.

Temperature Zones

Practical Tips

• Start at 180 °C and increase in 5-degree steps
• Finer grind often needs 5–10 °C lower temperature
• In cold environments, raise starting temp by 5 °C

The Solo 2 MAX battery lasts several sessions with typical use. For maximum lifespan, keep the battery between 20% and 80% and avoid deep discharge. USB-C charging with a quality power adapter speeds up charging.

Battery Tips

• Do not leave on the charger permanently — unplug after 100%
• For replaceable batteries: use original or recommended cells
• Battery performance drops in cold — let it warm up before sessions
• Pass-through charging (if supported) allows use while charging

Both Arizer portables with hybrid heating and glass vapor path. The Solo 3 V2 heats up in 15s (vs 30s), has 5000mAh battery and app control. The Solo 2 MAX is ~55 EUR cheaper.

Both Arizer portables with pure convection, glass stems and replaceable 18650 battery. The Solo 2 MAX has a bigger battery (3500mAh vs 2600mAh) and longer sessions. The ArGo is much more compact with its flat stem design and fits in any pocket.
