Do you mean you want to buy one or just want general info? Here’s a quick, practical guide and a few Australia-available recommendations so you can pick the right wireless charger for an Android phone.

Quick basics

• Standard: Most Android phones use the Qi wireless standard. Newer devices and accessories are moving to Qi2 (magnetic alignment, faster/more reliable charging). (Belkin.com)
• Power (speed): Common wireless outputs are 5W (slow), 7.5W (iPhone), 10–15W (many Androids). To get the fastest wireless charging your phone supports you need: (a) a charger that offers that wattage, and (b) a suitable high-power wall adapter/cable (some chargers include one). (Amazon.com.au)
• Form factor: pads (lay-flat), stands (useful for video/calls), multi-device docks (phone + earbuds/watch). Pick a stand if you use your phone while it charges; pick a pad for bedside or a low-profile desk setup. (Belkin.com)
• Case compatibility: many chargers charge through slim cases (1–5 mm). Thick or metal/magnet-containing cases can block charging. (Anker.com)
• Magnetic (Qi2 / MagSafe-style): Apple’s MagSafe is widely supported by Qi2-certified accessories. Android is beginning to adopt similar magnetic standards (e.g., Pixel “Pixelsnap” / Qi2-compatible developments and some phones are “Qi2 ready”). If you want magnetic alignment, check that both phone (or case) and charger support Qi2. (TechRadar.com)

Good picks available in Australia (These are examples of reliable models/brands you can find locally; prices vary by retailer.)

• Belkin BoostCharge 15W Wireless Charging Stand / Pad — Qi-certified, 15W for compatible phones, widely sold in Australia (includes power adapter in some SKUs). Good all-round stand option. (Belkin.com)
• Anker PowerWave / Anker 313 (10–15W pads/stands) — reliable and well-priced Qi chargers, pads and stands available in AU. Good value for daily use. (Amazon.com.au)
• Samsung Super Fast Wireless Charger Pad Duo / pads & stands — if you have Samsung phones/earbuds these official chargers support fast charging and multi-device setups. Available through major AU retailers. (BigW.com.au)
• Multi-device / budget hubs (brands like SwanScout, generic 3-in-1 chargers) — inexpensive multi-device stations exist in AU marketplaces; check outputs and that the phone coil/wattage meets your needs. (Quality and safety vary.) (au.SwanScout.com)

What to check before buying (short checklist)

• Is my phone Qi or Qi2 capable (or “Qi2-ready”)? If Qi2/magnetic alignment matters, confirm phone or case supports Qi2. (Wired.com)
• Charger output: do you want 10–15W (faster) or basic 5W? Match charger wattage to your phone’s supported wireless fast-charge spec. (Amazon.com.au)
• Included wall adapter/cable: some chargers include a suitable adapter; others don’t. Using a low-power adapter can limit charging speed. (Amazon.com.au)
• Safety/certification: Qi-certified is preferable; look for good brand reputations and warranties. (Belkin.com)

Price ranges in Australia (approximate)

• Basic Qi pad/stand (Anker, generic): ~A$25–70. (Anker.com)
• Branded 15W stands/pads (Belkin, Samsung): ~A$70–130 depending on model and whether adapter included. (Belkin.com)
• Multi-device Qi docks: A$50+ (wide variety; quality varies). (au.SwanScout.com)

• Point to the cheapest, highest-rated option available right now from Australian retailers (I can search current listings).
