Nice—here are compact, genuinely lightweight power-bank picks and quick buying tips so you can choose the best one for daily carry (pocket or small bag).

Top lightweight picks (great for daily use)

• Anker 622 Magnetic Battery (MagGo) — Best magnetic/pocket option for iPhone users

  • Capacity: 5,000 mAh; Wireless MagSafe-style attach (up to ~7.5W), USB‑C input/output. Weight: ~133–141 g (≈5 oz). Good for one light top‑up and hands‑free viewing (folding kickstand). (anker.com)

• Apple MagSafe Battery Pack — simplest MagSafe option if you want minimal weight + seamless attach

  • Official-style magnetic pack; very compact and light (about 113–115 g) but relatively small internal capacity (designed for quick on‑the‑go boosts rather than multiple full charges). Best if you want the least bulk while keeping your iPhone topped up. (macrumors.com)

• Anker PowerCore 10000 PD Redux — best pocketable USB‑C PD 10,000 mAh

  • Capacity: 10,000 mAh; USB‑C Power Delivery (≈18–22.5 W depending on variant), USB‑A output; weight about 190–195 g. Excellent balance of capacity, pocketability and fast USB‑C charging for daily phone/tablet use. (ubuy.co.id)

• Zendure SuperMini X3 (10000 mAh, 45W) — best if you want a compact 10k that can also fast‑charge larger devices

  • Capacity: 10,000 mAh (≈36 Wh); bidirectional USB‑C PD up to 45 W (so it can charge laptops like a MacBook Air at reduced speed) and weight around 200 g. Great if you want more power-per-gram and faster refill times. (powerbank.zendure.com)

Quick guidance and tradeoffs

• Pocketable = ≈5,000–10,000 mAh (weight ~100–220 g). 5,000 mAh units (or MagSafe-style 5K) are thinnest/lightest but usually only give one partial/full phone charge. 10,000 mAh is the sweet spot for daily carry if you want ~2 phone charges while still fitting in a pocket. (anker.com)
• Look for USB‑C Power Delivery (PD) if you want faster phone/laptop charging — 20 W+ is ideal for phones, 30–45 W if you want to top up a laptop. Zendure’s SuperMini X3 is an example of a higher‑W 10k unit. (powerbank.zendure.com)
• Airline/travel rule to remember: spare power banks must go in carry‑on only and most consumer banks ≤100 Wh are allowed without airline approval. (10,000 mAh ≈ 37 Wh; 20,000 mAh ≈ 74 Wh.) If you travel by air, check the battery’s Wh rating. (tsa.gov)
• Built‑in cables or built‑in Lightning/MagSafe connectors reduce what you need to carry but slightly increase size/weight—useful for minimalists (e.g., Anker’s Nano with integrated Lightning for Apple devices). (anker.com)
• Passthrough charging (charging the bank while it charges a phone) is convenient but can be slower and produce more heat—avoid relying on passthrough for fast refills if speed/heat are concerns.

Which to pick

• If you want absolute minimal bulk for an iPhone: Apple MagSafe Battery Pack or Anker 622 MagGo (both light and magnetically attach). (macrumors.com)
• If you want a true pocketable power bank that still gives 2+ phone charges: Anker PowerCore 10000 PD Redux. (ubuy.co.id)
• If you sometimes need to top up a tablet or a light laptop: Zendure SuperMini X3 (45 W) — still compact for a 10k but more capable. (powerbank.zendure.com)

If you’d like, I can:

• Narrow options by price range or phone model (Android vs iPhone),
• Compare 2–3 specific models side‑by‑side (weight, ports, real‑world charge counts, price),
• Or find the best current deals/sellers in the U.S. today.

Which would you prefer next?
