Complete Features & Benefits Breakdown
Wireless Charging Freedom

The QUACOA power bank features 15W wireless charging that's compatible with all Qi-enabled devices, including the latest iPhones, Samsung Galaxy phones, and Android flagships.
The wireless charging pad automatically detects your device and delivers the optimal power output, ensuring fast and safe charging every time. When wireless isn't an option, simply connect via the USB-A or Type-C ports for up to 60W total output.
Massive Power Capacity
With 20,000mAh of lithium polymer battery capacity, this power bank delivers exceptional performance:
| Device | Approximate Charges |
|---|---|
| iPhone 15 Pro | 4-5 full charges |
| Samsung Galaxy S24 | 4-5 full charges |
| Google Pixel 8 | 4-5 full charges |
| iPad Mini | 2 full charges |
| Wireless Earbuds | 15+ charges |
The premium lithium polymer cells provide consistent power delivery while maintaining a compact, lightweight design. An LED display shows remaining battery percentage at a glance, so you're never caught off guard.
Dual Charging Capability
Never choose between devices again. The QUACOA power bank features three output ports:
- 2x USB-A Ports (5V/3.0A each)
- 1x Type-C Port (5V/3.0A)
- Wireless Charging Pad (15W)
You can charge your smartphone, tablet, wireless earbuds, and smart watch—all simultaneously. The intelligent power management system automatically distributes current to each device for optimal charging speeds.
Built for Outdoor Adventures
Unlike fragile electronics meant only for the boardroom, the QUACOA WH628A is engineered for real-world use:
Rugged Durability
- Premium ABS + Silicone Construction – Shockproof and impact-resistant

Solar Charging Innovation
The integrated solar panel with 20-23% efficiency provides emergency recharging when traditional power sources aren't available. While solar charging is slower than wall outlet charging, it can be a literal lifesaver during extended outdoor trips or emergency situations. A green indicator light shows when solar charging is active.
Emergency LED Lighting
Two bright LED flashlights integrated into the power bank serve multiple purposes:
- Nighttime navigation on dark trails
- Campsite illumination when tent camping
- Emergency signaling if stranded
- General-purpose lighting during power outages
Long-press the side button for approximately 5 seconds to activate the flashlight mode.

Frequently Asked Questions (FAQ)
How long does it take to fully charge the power bank?
Using a standard 5V/1.6A wall charger, the 20,000mAh power bank takes approximately 12-14 hours to fully recharge. Using a higher-output charger (not included) can reduce this time. Solar charging is significantly slower and should be used as a backup power source.
Can I charge my laptop with this power bank?
The QUACOA WH628A delivers up to 60W total output across all ports. While it won't fast-charge a laptop requiring 65W+ (like MacBook Pro), it can provide emergency charging for laptops with USB-C Power Delivery support. For dedicated laptop charging, consider a power bank with 65W+ output.
Is wireless charging safe for my phone?
Yes. The QUACOA power bank includes over-current, over-voltage, and short-circuit protection to ensure safe wireless charging. The 15W output is within the safe range for all Qi-compatible devices.
Can I take this power bank on an airplane?

Is the power bank actually waterproof?
The QUACOA WH628A features IP54 dust and splash protection. This means it's protected against water splashes from any direction but should not be submerged in water. The strong USB caps help seal ports against moisture.
