All-in-one 12000mAh power bank
The Rngsnoy AC-02F combines a 12000mAh lithium-polymer cell with a built-in AC wall plug, USB-C and USB-A ports plus integrated Lightning and USB-C cables. It delivers up to 22.5W output for phones, tablets and other USB devices. A digital display shows remaining capacity at a glance.
Built-in plug and cables remove extra gear
The folding AC prong recharges the bank itself in 5 hours, or 3.5 hours via the PD 18W USB-C input. Pass-through charging powers connected devices while the bank refills. Integrated cables and three output ports — USB-A 22.5W, USB-C PD 20W and USB-A 10W — let multiple devices charge simultaneously without carrying separate cords.
Suits travellers wanting one compact unit
The 12000mAh capacity provides roughly two phone charges or a single tablet top-up, fitting in a pocket at 220 grams. Buyers who need more storage for multi-day trips or who require higher wattage for laptop charging should look at something else.

Questions about this item
How long does the built-in lithium-polymer battery last before it needs replacing?
The 12000mAh lithium-polymer cell is rated for hundreds of full charge cycles; with daily top-ups it typically delivers several years of service before capacity drops noticeably.
What limits the 22.5W output during extended charging sessions?
The 4.5A maximum current and internal thermal management will throttle the 22.5W USB-A port if the power bank overheats during sustained high-load use.
How hot or noisy does the unit get when charging multiple devices all day?
It runs silently with no fan; the polycarbonate shell stays warm but safe to touch thanks to the 5V 4.5A power limit and pass-through charging design.
