Design & Build Quality
The Oraimo PowerNova Q21 features a sleek and robust design, making it ideal for both travel and daily use. Measuring 160mm x 75mm x 25mm, it’s compact enough to fit into a backpack or large purse. Weighing around 410 grams, it’s slightly heavier than smaller-capacity power banks but expected for its 20,000mAh battery.
The exterior is made of high-quality matte plastic, which is resistant to fingerprints and provides a secure grip. Unlike glossy alternatives, the matte finish keeps the power bank looking clean even after prolonged use.
One standout feature is the LED digital display, which clearly shows the remaining battery percentage, helping users know exactly when to recharge. The button placement is simple and user-friendly, with the power button located on the side for quick access. Overall, the design balances portability, durability, and visual appeal.
Battery Capacity & Performance
The 20,000mAh battery in the PowerNova Q21 is its most notable feature. This high capacity is enough to fully charge an average smartphone 4-5 times, or a tablet 1-2 times, depending on battery size.
Oraimo uses Li-Polymer battery technology, which is more efficient and safer than older Li-Ion batteries. The rated capacity is slightly lower than the actual capacity, but in real-world usage, it still delivers impressive performance.
Power delivery is stable and consistent, with minimal voltage drops even when charging multiple devices simultaneously. Users can confidently rely on this power bank for extended trips or emergency situations where access to wall power is limited.
Charging Speed & Technology
The PowerNova Q21 supports multiple fast-charging technologies:
- PD 3.0 (Power Delivery) for USB-C devices, including smartphones and tablets.
- QC 3.0 (Quick Charge) for compatible Android devices.
- FCP (Fast Charging Protocol) for older Huawei and Oraimo devices.
With a maximum output of 22.5W, it can charge a typical smartphone from 0% to 50% in around 30-35 minutes, depending on the device. The USB-C input/output port also supports faster self-charging of the power bank itself, taking approximately 4-5 hours to reach full capacity using a PD-compatible charger.
The real-world charging experience is smooth and reliable. Devices begin charging immediately upon connection, with no noticeable lag or interruptions.
Ports & Connectivity
The Oraimo PowerNova Q21 comes with 3 ports:
- 2 x USB-A outputs for traditional charging cables.
- 1 x USB-C port that functions as both input and output.
The port setup allows you to charge up to three devices simultaneously, which is convenient for users carrying multiple devices. While it does not offer wireless charging, the versatility of PD and QC technology compensates by delivering fast charging for almost all modern devices, from smartphones and tablets to Bluetooth headphones and portable speakers.

Oraimo prioritizes user safety with its Smart Safety System, which includes:
- Overcharge Protection – prevents devices from receiving excessive current.
