Baseus Comet Series 20000mAh Power Bank – Two Cables Built In, Zero Cables to Carry
iPhone user? Android fan? Traveling with mixed devices? The Baseus Comet Series Dual-Cable 20000mAh 22.5W Power Bank solves the cable problem forever. With a built-in Apple Lightning cable AND a USB-C cable, everyone in your group can charge without a single separate cord. Add a stunning transparent shell and real-time digital display, and you have one of the best-value power banks available in Bangladesh today.
🔌 Two Built-In Cables — For Every Phone in Bangladesh
The standout feature of the Baseus Comet is its dual integrated cables:
- MFi-Certified Lightning Cable (20W PD) — For iPhone 14, 13, 12, 11, and all Lightning devices. Charges iPhone 13 to 60% in just 30 minutes.
- USB-C Cable (22.5W SCP) — For Samsung, Xiaomi, Realme, OPPO, OnePlus, and all USB-C Android phones.
No more arguing over cables. No more carrying extra cords. The Comet has everyone covered.
🔋 20000mAh — Enough for Days Without Power
Bangladesh’s load-shedding doesn’t have to slow you down. With 20000mAh of polymer lithium battery, the Baseus Comet can deliver roughly 4–5 full charges for a 4000mAh smartphone. The battery conversion efficiency is over 75%, so you get more usable power than most competing banks at this price point.
✨ Transparent Shell — Style Meets Function
The see-through Comet Series design is genuinely eye-catching. You can see the internal components through the clear casing — a modern, techy look that complements any aesthetic. It’s the kind of power bank people notice and ask about.
📟 Smart Digital Display — Always Informed
The LED digital display shows remaining battery percentage in real time. You know exactly when to recharge, how much to share, and when you need to plug in. No more “I thought it was full” surprises.
