Charmast Power Bank 10000mAh portable charger

This compact power bank from Charmast brings built-in cables and multiple ports together to keep several devices topped up while on the move. With a 10,000 mAh capacity and an LED battery readout, it is useful for daily commuting, travel and busy days when you need to charge phones and tablets without extra cables.

Key Points

The unit integrates three attached cables covering Micro USB, USB‑C and Lightning connections, plus additional USB‑A and USB‑C ports, so you can charge a mix of devices at once. The slim housing includes a clear digital LED display that shows remaining charge as a percentage, which makes it easy to plan recharging. According to the manufacturer, the power bank supports simultaneous charging of up to six devices using a combination of the integrated leads and the standard USB outputs. Note that charging speeds depend on the connected device and cable.

Technical Specifications

• Name: Charmast Power Bank X 4
• Capacity: 10000 mAh
• Outputs: 6 outputs total (3 built‑in cables, 2 USB‑A, 1 USB‑C)
• Inputs: 3 inputs (Micro USB, USB‑C, USB‑A via built‑in cable)

The Best of This Model

This model emphasises convenience over carrying spare leads, since the built‑in cables reduce clutter and the need to remember multiple chargers. The LED readout aims to remove guesswork about remaining battery by giving a precise percentage. It also uses Smart E 3.0 and VoltageBoost technologies according to the manufacturer, which identify connected devices and adapt output to deliver faster charging where supported.

Usage Recommendations

For efficient recharging of the power bank itself, use the USB‑A built‑in cable or a USB‑C input if you have a compatible fast charger. Place the power bank in a ventilated area while charging and avoid exposing it to high temperatures. Consider that a 10,000 mAh bank will typically deliver around one to two full charges for many modern smartphones depending on model and usage, so it is best for day trips and overnight use rather than extended multi‑day trips.
