20000mAh High-Capacity Battery
The Baseus Q3 is powered by a 20000mAh / 3.7V battery with a total energy capacity of 74Wh, providing a substantial reserve of portable power for everyday electronics. Its premium Polymer Lithium battery offers an energy conversion rate of at least 75% and can provide multiple recharges depending on the battery capacity and charging efficiency of the connected device. The large capacity makes the Q3 suitable for smartphones, tablets, handheld gaming devices, and selected USB-C laptops, while remaining practical for commuting, travelling, office use, and emergency power backup.
45W Bi-Directional Fast Charging
The Baseus Q3 supports up to 45W bi-directional charging through USB-C, allowing the same interface to provide fast power output and high-speed input. The USB-C input/output supports 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/2.25A, reaching a maximum of 45W. This enables compatible smartphones, tablets, and selected laptops to recharge efficiently while also allowing the 20000mAh power bank itself to be replenished at up to 45W when paired with a suitable fast-charging adapter.
Dual Built-in USB-C & Lightning Cables
Convenience is one of the strongest features of the Baseus Q3, thanks to its integrated USB-C and Lightning charging cables. The built-in USB-C cable supports up to 45W output, while the integrated Lightning cable delivers up to 27W. Having both cables attached directly to the power bank reduces the need to carry additional charging cables in a backpack or travel bag. This all-in-one configuration is particularly convenient for users carrying devices from different ecosystems, including compatible iPhone, Android, and USB-C devices.
Charge Up to 4 Devices Simultaneously
The Baseus Q3 provides four different charging outputs, allowing up to four compatible devices to be connected simultaneously. Users get a dedicated 45W USB-C output, 45W built-in USB-C cable, 27W built-in Lightning cable, and USB-A output supporting up to 22.5W. This flexible output configuration makes the Q3 an excellent choice for users who regularly carry multiple electronic devices or need to share portable power with family members, colleagues, or travel companions without relying on several separate power banks.
1.5-inch LCD Smart Digital Display
A clear 1.5-inch LCD digital display provides significantly more useful charging information than conventional LED indicator lights. The smart display shows the remaining battery percentage in real time while also providing voltage information and active fast-charging status indicators. Users can therefore monitor the available battery reserve more accurately and quickly determine whether sufficient power remains for additional charging. This makes power management much easier during travel, long working days, outdoor activities, or situations where access to a wall outlet may be limited.
Wide Protocol Support & 9-Layer Protection
The Baseus Q3 supports an extensive selection of fast-charging protocols, including PD3.0, QC4+, PPS, SCP, FCP, and AFC, providing broad compatibility with supported devices from different manufacturers. A comprehensive 9-layer protection system is designed to protect connected electronics during charging and improve overall power-management safety. The power bank is also listed with CE, ROHS, and FCC certifications, combining high-speed charging, broad compatibility, and multiple safety features in a compact portable charging solution.
