- Tablet (6000-8000 mAh): 2-3 full charges.
- Headphones, fitness bracelets, action cameras: more than 15 loads.
AiPower Technology: Smart and Safe Charging
One of the concerns when using external batteries is charging safety . The Aukey PB-N36 is equipped with AiPower technology , which automatically detects and adjusts the optimal current for each connected device. This means that each USB port adaptively delivers up to 2,4 Amps , ensuring maximum safe charging speed without the risk of overheating or overcharging.
Thanks to this technology, the power bank can charge two devices simultaneously without losing efficiency on either port, and it also protects both your devices and the internal battery itself from power surges, short circuits, and other electrical anomalies. Charging stops automatically when the device reaches 100% , preventing premature wear on your smartphone or tablet batteries.
In addition, AiPower technology is compatible with a wide variety of USB devices: from the latest Android phones to iPhones, iPad tablets, Kindles, digital cameras, Bluetooth speakers, smartwatches, and all kinds of accessories that are so popular today.
Thus, the Aukey PB-N36 is not only powerful and versatile, but also a safe option for demanding users who prioritize the protection of their devices.
Inputs and outputs: maximum flexibility for charging and recharging
The PB-N36 has two USB (AiPower) outputs capable of supplying up to 2,4A each and a combined maximum of 3,4A, allowing you to charge two devices at the same time , whether it's two Android phones, a smartphone and a tablet, or a phone and wireless headphones.
To charge the external battery itself, you can use either a Micro USB or Lightning cable , so you only need one of the cables you already use for your phone or tablet. This is very convenient and reduces the number of accessories you need every day. This flexibility is key for those who use devices from different brands and operating systems.
Among the most practical details are:
- Integrated LED light: Ideal for emergencies or as a portable flashlight in low-light environments.
- LED Indicator: Displays the remaining battery level, making it easy to know when it's time to recharge the power bank.
Universal Compatibility: Suitable for Android, iOS and more
The Aukey PB-N36 has been designed for complete compatibility . Whether you have an Android phone, an Apple device (iPhone or iPad), a tablet, a portable game console, wireless headphones, an e-reader, or any other USB-chargeable gadget, this portable battery can efficiently recharge it.
With both inputs (Micro USB and Lightning) and dual USB outputs, you can not only charge two devices at once, but you can also recharge the battery using any cable of your choice. It also fits perfectly with other less common devices such as GoPro cameras, GPS navigators, portable routers, Bluetooth speakers, and e-readers. This makes it an essential accessory for any trip, event, mobile work, or emergency situation.
The ability to supply the appropriate intensity to each device, combined with advanced protection mechanisms, guarantees the integrity of your devices and the external battery itself.
Design, materials and portability
The design of the Aukey PB-N36 is one of the features that most distinguishes it from other batteries on the market. Made of high-strength matte ABS plastic , it withstands heavy use, minor bumps, and accidental drops. Its approximate dimensions are 149,5 x 82,5 x 21 mm , and it weighs between 387 and 449 grams , making it compact and easy to carry in a backpack, purse, or even the car's glove compartment.
Another practical advantage is the inclusion of a durable fabric case in the packaging, ideal for protecting the battery when you're on the go. The set typically includes, in addition to the battery, a USB-Micro USB cable and a user manual.
- Strength and durability: Excellent finish and materials that prevent scratches and deterioration from daily use.

Charging time and energy efficiency
One common question is how long it takes to recharge a 20.000 mAh battery. Using a 2A charger, the Aukey PB-N36 can be fully recharged in approximately 10 to 13 hours , depending on both the charger and cable used. This time can be reduced if you use higher-capacity chargers, within the battery's limits.
During charging, the LED indicator lets you see the battery status at a glance, alerting you when charging is complete. Furthermore, the internal electronics ensure that energy is used to its fullest potential, providing a real-world capacity very close to the theoretical rating, which isn't always the case with other similar models.
Protection and security: peace of mind for your devices
