## Long description

GUESS GUL23PB4TLBK 4000 mAh portable charger in black is a compact powerbank designed to provide emergency energy for smartphones and small USB-powered devices. Its 4000 mAh capacity delivers additional runtime for calls, navigation, messaging and light app use. The unit includes a standard USB output for charging devices and a rechargeable input that may be micro-USB or USB-C depending on the supplied cable—check compatibility with your charger cable. The slim, pocketable design supports daily carry and travel situations where a quick top-up is needed.
Advantages
The powerbank offers a balance between capacity and portability, allowing users to extend device runtime without carrying a heavy battery pack. Its neutral black finish and compact dimensions make it unobtrusive in a bag or pocket. Standard USB output ensures compatibility with a wide range of smartphones and USB accessories, while the 4000 mAh capacity is sufficient for most emergency top-ups and short trips.
Suitable for
 Smartphone emergency charging during the day
 Short travel, commuting and business trips
 Charging small USB devices such as earphones, fitness trackers, and Bluetooth accessories
 Keeping in a bag or car for occasional top-ups
When it may not be suitable
Because the capacity is 4000 mAh, this powerbank may not fully recharge large-capacity smartphones more than once or support extended use of power-hungry devices such as tablets or laptops. It is intended for emergency and short-term charging rather than as a primary power source for multiple devices over prolonged periods.
Key specifications
 Battery capacity: 4000 mAh
 Colour: black
 Output: standard USB port for device charging
 Input: rechargeable via micro-USB or USB-C (check cable supplied)
 Form factor: compact, pocketable portable charger
How to use
Charge the powerbank using the provided input cable connected to a compatible USB power adapter or computer USB port until the internal charge indicator (if present) shows full. Connect your smartphone or USB device to the powerbank using a standard USB cable, then press any required power button to start charging. Monitor device charge level and disconnect when charging is complete to conserve remaining power.
What to consider before purchase
 Confirm the input cable type supplied (micro-USB or USB-C) and compatibility with your charger or cables.
 Assess whether 4000 mAh capacity meets your typical charging needs (single top-ups versus multiple full charges).
 Check device charging power requirements; high-power devices may charge slowly or not fully from this unit.
Usage recommendations
Store the powerbank partially charged if not used for long periods and avoid extreme temperatures. For best results carry a short USB cable that matches both the powerbank input and your devices' charging connector. Use the GUESS powerbank for emergency top-ups and everyday portability rather than long continuous powering of high-consumption devices.
