The Foneng PX136 is a dependable 20000mAh power bank built for everyday backup charging when you’re on the move. Designed with dual polymer lithium battery cells, it delivers reliable performance for charging smartphones multiple times, and it’s also suitable for powering smaller daily devices like earbuds and smartwatches. If you often travel, study, or work long hours away from a wall socket, this power bank helps you stay connected without carrying a bulky charger setup.
With a 20000mAh capacity, the PX136 is made to support extended usage across the day. Depending on your phone’s battery size and charging efficiency, it can typically charge most smartphones around three to four times on a full charge. This makes it a practical choice for users who want a single power bank that can cover multiple charging needs—especially during busy schedules, commutes, or trips where power outlets are limited.
The PX136 supports fast charging up to 22.5W, helping compatible Android and iOS devices receive power more quickly than standard charging. On the output side, USB-A and Type-C both support up to 22.5W (USB-A: 22.5W Max, USB-C: 22.5W Max with PD/PPS). Lightning output is rated up to 12W Max, giving you flexible options for different device types. This multi-port approach is especially useful when you need to charge more than one device or when you’re switching between phone models with different connectors.
Recharging the power bank is convenient thanks to its Type-C input design. For charging your devices, the PX136 provides multiple output ports—USB-A, Type-C, and Lightning—so you can connect the right cable for each device without constantly swapping accessories. This is a smart everyday feature for households and shared workspaces where different users may rely on different charging standards.
The built-in LCD power indicator displays the remaining battery percentage, making it easier to plan charging time and avoid unexpected shutdowns. Instead of guessing how much power is left, you can monitor the level at a glance and decide when to top up the power bank. This is particularly helpful during travel days or long work sessions when you want predictable performance.
Despite its large capacity, the PX136 is designed to remain portable. It measures 149.4 x 67.6 x 30.5mm and weighs around 443g, which makes it suitable for backpacks and travel bags without feeling overly heavy. The silver color finish and solid grip help it feel comfortable in-hand during use, while the overall build is intended to handle regular daily carry.
The PX136 includes safety-focused power management to help protect connected devices from overcharging, overheating, and voltage fluctuations. This helps ensure stable charging behavior for your phone and other compatible gadgets, making it a practical backup power solution for daily use. For best results, use compatible cables and chargers for your devices and keep the power bank in a ventilated area during charging.
This power bank is ideal for students, professionals, and travelers who want a high-capacity backup with fast charging support and a clear LCD battery indicator. If you frequently charge multiple devices throughout the day or need a reliable power source for long hours outside, the Foneng PX136 offers a balanced combination of capacity, charging speed, and versatile port support—making it a strong everyday companion for Bangladesh users.
