S20 ULTRA 5G CHARGING CARD

🔋 Charging specs of the S20 Ultra

• The S20 Ultra has a 5000 mAh (typical) battery.

• Wired fast‑charging: the phone supports 25 W fast charging with the charger included.

• It also supports up to 45 W wired charging (with a separately‑sold charger) to push it even faster.

• Wireless charging: up to ~15 W for wireless Qi / PMA charging.

• Reverse wireless charging (i.e., the phone can charge other devices wirelessly) is also supported.

A summary: the S20 Ultra is a high‑end phone with large battery and fast‑charge capabilities — so any “charging card” accessory for it should aim to match or complement those specs.

🛠 What a “Charging Card” Accessory Means & Description

By “charging card” I interpret an accessory that may be:

• A slim portable charger/power‑bank shaped like a card (thin, compact) to carry around, or

• A card‑style wireless charging pad (thin pad you place the phone on), or

• A compact charger block + cable kit styled for convenience, possibly labelled “card‑size” for portability.

Here’s how a good one should be described for the S20 Ultra, and what features it should include:

Ultra‑Slim Power‑Card Charger for Samsung Galaxy S20 Ultra
• Form factor: credit‑card‑thin (for example ~110 × 70 × 10 mm) for easy portability in wallet/pocket.
• Output (wired mode): Supports USB‑C output and up to 25 W (or better up to 45 W) via USB Power Delivery (PD) with PPS support, so the S20 Ultra’s wired fast‑charging capability is fully utilised.
• Wireless mode (if included): Qi‑certified wireless charging pad format with up to ~15 W output, suitable for the S20 Ultra’s wireless charge specs.
• Cable included: High‑quality USB‑C to USB‑C (or USB‑A to USB‑C depending on implementation) rated for high current/voltage (to support full speed).
• Safety: Over‑current, over‑voltage, thermal protection, short‑circuit safe.
• Compatibility: Explicitly mentions compatibility with Samsung Galaxy S20 Ultra (and other S20 series phones).
• Design/usability: Non‑slip surface (if wireless pad), indicator LED for charging status, compact size for travel.
• Branding & warranty: From a reputable brand, includes warranty/support.

Key Features & Why They Matter

• High output rating: If the accessory only supports 10‑15 W wired, the phone will charge slower than its capability. For best experience you want something that supports at least 25 W (or 45 W if you opt for the extra‑fast charger).

• Correct protocol support: The S20 Ultra uses USB‑C and supports PD (USB Power Delivery) and Samsung’s fast‑charging technologies. Using a cheap incompatible charger/cable might result in slower charging or the phone not showing “Super fast charging”.

  As one user commented:
  “None of my old USB‑C cables were rated high enough for my new phone … the one that came with my charger work great.”

• Wireless vs wired trade‑offs: Wireless (~15 W) is convenient, but wired supports much faster charging (25 W or 45 W). If you choose a card‑style wireless pad you should expect slower speeds compared to wired.

• Quality & safety: Fast charging generates heat. A good accessory handles it safely, maintains longevity of the phone’s battery, and avoids damage.

• Portability & usability: The “card” form suggests ultra‑slim / travel‑friendly. That’s a plus if you carry it around.

✅ What to Look for (Checklist)

When buying a charging‑card accessory for your S20 Ultra, ensure:

• It supports USB‑C output (for wired) and/or Qi wireless (if wireless pad).

• It offers 25 W wired output or higher (ideally up to 45 W if you want max speed).

• The cable supplied (or recommended) is high‑quality and rated for fast‑charging.

• The accessory mentions support for the correct fast‑charging protocols (PD, PPS, Samsung Adaptive Fast Charge, etc.).

• If wireless: the pad aligns well, supports 15 W output, and the phone placement will work (especially given the camera bump on S20 Ultra).

• It’s from a reliable brand, has warranty and good reviews.

• It fits your size/portability needs (slim card shape if that’s what you want).

• Price/availability in your region (Pakistan / Karachi) and check for compatibility with local power/voltage if included charger block.
