havit PB35 Power Bank Review: A Massive 20000mAh Portable Charger

In today’s always‑on world, having a reliable power source that can keep multiple devices running throughout the day is essential. The havit PB35 power bank arrives as a purpose‑built solution, engineered specifically for users who demand high capacity, versatile charging options, and the convenience of a built‑in cable . With its 20000mAh battery, integrated USB‑C cable, and support for up to 22.5W fast charging, this power bank is designed to be the ultimate travel companion for professionals, students, and families alike.

Spacious Capacity in a Portable Form

At the heart of the havit PB35 power bank lies a substantial 20000mAh lithium‑polymer cell with a total energy of 77Wh . This capacity is large enough to charge a typical smartphone four to five times, a tablet twice, or provide a significant power boost to a laptop when outlets are scarce. Despite its high capacity, the power bank maintains a compact footprint of 138 x 72.5 x 25.5 mm and weighs 332g, making it easy to slip into a backpack, messenger bag, or even a large pocket. The ABS+PC material construction provides durability while keeping the weight manageable for everyday carry.

Built‑In USB‑C Cable for Ultimate Convenience

One of the standout features of the havit PB35 power bank is its integrated USB‑C cable, cleverly built into the body of the unit . This eliminates the need to carry a separate cable for charging your primary devices, reducing clutter and ensuring you’re never left without a way to connect. The built‑in cable supports both input and output, meaning you can use it to charge the power bank itself or to power your devices, with a maximum output of 22.5W (5V/3A, 9V/2.22A, 12V/1.67A, 10V/2.25A). This makes it ideal for fast‑charging compatible smartphones, tablets, and other USB‑C gadgets.

Triple‑Port Output for Multi‑Device Charging

Beyond the built‑in cable, the havit PB35 power bank features two additional ports: one USB‑C and one USB‑A. Together, they allow you to charge up to three devices simultaneously, making it perfect for busy households, group travel, or when you need to power multiple gadgets at once.

• USB‑C Port: Delivers up to 20W (5V/3A, 9V/2.22A, 12V/1.67A) with Power Delivery (PD) support.

• USB‑A Port: Supports up to 22.5W (5V/3A, 9V/2A, 12V/1.5A, 10V/2.25A), compatible with Qualcomm Quick Charge and other fast‑charging standards.

• Built‑in USB‑C Cable: Up to 22.5W, offering the same high‑speed charging as the USB‑A port.

When charging multiple devices, the power bank intelligently allocates power to ensure stable and safe delivery, so you can charge a phone, a tablet, and a pair of wireless earbuds all at once without worry.

Fast Self‑Charging with 18W Input

Recharging the havit PB35 power bank itself is equally quick and convenient. It accepts up to 18W input via the USB‑C port or the built‑in USB‑C cable (5V/3A, 9V/2A, 12V/1.5A). This means you can fully replenish the 20000mAh battery in a fraction of the time it would take with a standard 5W charger. Whether you use a compatible wall adapter or a laptop USB‑C port, you’ll spend less time waiting and more time powered up.

Universal Compatibility and Safety

The havit PB35 power bank is designed to work seamlessly with a wide range of devices, from iPhones and iPads to Android smartphones, tablets, and even some USB‑C laptops. For Android users, the power bank supports the PD and PPS fast‑charging protocols that are common in modern devices, ensuring your phone charges at its optimal speed. As part of the broader Android ecosystem, this power bank is ready to keep your devices powered throughout the day, whether you’re using a Google Pixel, Samsung Galaxy, or any other compatible device.

Safety is built into every aspect of the havit PB35 power bank. Integrated protection circuits guard against overcharging, over‑discharging, short circuits, and overheating, giving you peace of mind whether you’re charging at home, in the office, or on the road.
