10N Magnetic Snap-On Attachment — MagSafe Compatible: A 10N internal magnet ring aligns and secures the bank to the iPhone 12 through 17 series in a single snap, maintaining coil-to-coil alignment during movement and hands-free use — no cable, no pad positioning required. MagSafe-compatible case required for best performance; thick, metal, or non-MagSafe cases may impair attachment and wireless charging.
Qi 15W Wireless Charging Output (7.5W for iPhone): Delivers up to 15W wirelessly to compatible Android devices and 7.5W to iPhone 12–17 series — the standard wireless fast-charge speed for this bank class, providing meaningful charge rates rather than trickle output during use.
PD 20W USB-C Output and Input: The USB-C port handles both 20W output to a second wired device and 20W input for self-recharging via a PD wall adapter, with support for PD3.0, PD2.0, PPS, QC3.0, QC2.0, and AFC protocols covering Apple, Samsung, Huawei, and OPPO device ecosystems.
37Wh Capacity — Airline Carry-On Compliant: At 37Wh the bank is well within the IATA 100Wh limit for lithium-ion batteries in aircraft cabin baggage, making it suitable for international travel without airline pre-approval or documentation.
Slim Silicone Body at 220g — Pocket-Portable: Soft silicone casing provides a skin-friendly, grip-enhancing, fingerprint-resistant surface in a neutral beige tone; at 106 × 69 × 19mm and 220g, the bank adds minimal bulk to a phone when attached and fits a trouser or jacket pocket comfortably.
PD 20W USB-C Two-Way Fast Charging: The USB-C port delivers PD3.0 20W to connected devices and accepts up to 20W input for self-recharging via a compatible PD wall adapter — bringing the bank to full in approximately 3 hours, three times faster than a standard 5W charger.
22.5W USB-A Output via QC3.0 and SCP: The USB-A port supports Qualcomm QC3.0, Huawei Super Charge, and Samsung AFC protocols — covering the fast-charging standards built into a wide range of Android smartphones without requiring a USB-C cable or adapter.
Slim 16.5mm Metallic Profile with Digital LED Display: A metallic case provides durability and a premium feel at just 16.5mm thick — genuinely shirt-pocket portable — while a digital LED display shows exact battery percentage at a glance rather than relying on a vague 4-LED indicator system.
37Wh Capacity — Airline Carry-On Compliant: The 37Wh energy rating is well within the IATA 100Wh international airline hand-luggage limit, requiring no prior approval or documentation for cabin baggage on domestic or international flights.
Low-Current Mode and Comprehensive Safety Protection: Long-pressing the power button activates a trickle output mode for small accessories; the bank also carries over-voltage, over-current, over-charge, over-discharge, over-temperature, and short-circuit protection, certified to CE, RoHS, and FCC standards.
100W Single-Port USB-C Output via PD3.0: USB-C1 outputs up to 100W — sufficient to fast-charge virtually any USB-C laptop including MacBook Pro, Dell XPS, and HP Spectre at near-wall-adapter speed; iPhone 15 reaches 60% in 30 minutes from the same port.
Two-Way Fast Charging — Full Self-Recharge in 1.6 Hours: Pass-through charging allows 65W input on USB-C1 while the bank simultaneously outputs to connected devices; at 65W the bank recharges from flat in approximately 1.6 hours — five times faster than a standard 5W charger.
72Wh Capacity — Airline Carry-On Compliant: The 72Wh rated energy falls comfortably within the IATA 100Wh limit for lithium-ion batteries in aircraft cabin baggage, making the PB720 suitable for international air travel without airline pre-approval.
Three-Port Simultaneous Output with Low-Current Mode: USB-C1 (100W), USB-C2 (30W), and USB-A (22.5W SCP/QC3.0) operate concurrently; long-pressing the power button activates a low-current trickle mode for small accessories such as earbuds and fitness trackers.
21700 Cells with UL 94 V-0 Flame-Retardant Housing: High-energy-density 21700 cells enable 20% smaller and lighter construction than comparable capacity banks using older cell formats, while the V-0 rated casing provides a certified level of fire resistance for safer high-power operation.
