Ugreen PB770 – Best High-Capacity 300W Fast Charging Power Bank in Bangladesh
The Ugreen PB770 (Model 25286) is a powerhouse designed for those who cannot afford to run out of juice. With a massive 48000mAh capacity and a staggering 300W total output, this power bank sits somewhere between a traditional portable charger and a full-scale power station. If you are looking for an original, high-performance charging solution that can handle your MacBook, iPhone, and other gadgets all at once, this is the official choice for you.
In Bangladesh, where load shedding can hit at the most inconvenient times, having a reliable backup is a necessity. Whether you are a freelancer working from a cafe in Dhanmondi, a university student prepping for exams during a power cut, or an adventurer heading to Sajek Valley, the Ugreen PB770 ensures your productivity never stops. Its robust build and high-speed charging capabilities make it a top-tier gadget for the local market.
Key Features of Ugreen PB770
- 48000mAh Massive Capacity: Keep your devices running for days without needing a wall outlet.
- 300W Total Output: Charge multiple high-power devices like laptops and tablets simultaneously.
- PD 3.1 140W Fast Charging: The USB-C1 port supports 140W output, perfect for the latest MacBook Pro models.
- LiFePO4 Battery Cells: Uses automotive-grade cells that last up to 3000+ cycles, far outperforming standard lithium batteries.
- Smart Digital Display: Real-time monitoring of input and output wattage so you know exactly how much power is left.
- 5-Port Charging: Includes 3 USB-C ports and 2 USB-A ports to cover all your charging cables.
Battery Performance & Longevity

The standout feature of the Ugreen PB770 is its LiFePO4 battery technology. Most power banks in the market use standard lithium-ion cells that degrade after 300-500 charges. However, this Ugreen model is built to last. It maintains over 80% capacity even after 3,000 charge cycles. This means even with daily use in the humid weather of Bangladesh, this power bank will serve you for years. It is a long-term investment for anyone who needs consistent power on the move.
Design & Practical Utility

Despite its huge capacity, the Ugreen PB770 remains manageable with its integrated carrying handle. It weighs around 1.6kg, making it sturdy yet portable for car trips or keeping in your backpack. The built-in LED light is a lifesaver during Dhaka’s frequent load shedding. It features high, low, and SOS modes, providing enough light to brighten up a room or help during emergency roadside repairs at night. The anti-slip rubber pads on the bottom ensure it stays firmly on your desk while charging multiple devices.
Safety & Multi-Device Compatibility

Safety is a priority with the Ugreen PB770. It features an advanced NTC temperature control system that monitors heat 200 times per second to prevent overheating. This is crucial when charging at high speeds like 140W. It is fully compatible with MacBook Pro, iPad Pro, iPhone 15/16 series, Samsung Galaxy S24, and even low-power devices like Bluetooth earbuds or smartwatches. You can charge a laptop at 140W while still having enough power to fast-charge two other phones at 100W and 60W respectively.

- Remote Workers & Freelancers: Stay online and keep your laptop charged during long power outages.
