Compact 10000 mAh power bank for daily carry
The JONKUU O10Blue is a slim lithium-polymer power bank designed for travellers and commuters who need reliable phone charging without bulk. Its 10000 mAh capacity fits in a wallet-sized footprint of 16 by 7.5 by 2 centimetres and weighs 220 grams. Built-in cables for iOS and Type-C devices plus a USB-A port cover most phones, tablets and headphones in one unit.
Passive cooling with intelligent protection
The unit relies on natural convection and an internal safety circuit that guards against overcharging, overdischarging, short circuits and overheating. No fan means silent operation in a pocket or bag. Input and output run at 5 V 3 A, delivering 22.5 W so a typical phone reaches 50 percent charge in roughly 40 minutes while the bank itself stays cool to the touch.
Five-device charging with no extra cables
Two integrated cables and one USB-A port let you power up to five devices at once, removing the need to pack separate leads. The Type-C port handles both input and output, so the same cable recharges the bank and your USB-C gear. Universal 99 percent compatibility suits mixed iOS and Android households, while the slim profile slips into tight organiser pockets or a jacket sleeve.

Questions about this item
How do I start charging my phone with the built-in cables, and what step do people forget?
Plug the built-in Type-C or iOS cable directly into your phone; the bank begins charging automatically, but users often forget to press the power button first to activate the output.
What part will need replacement first as the power bank ages?
The internal 10000 mAh lithium-polymer cells degrade after hundreds of cycles; the whole unit is replaced when capacity drops noticeably.
What limits how long it can sustain 22.5 W fast charging?
Thermal protection kicks in during sustained 5 V 3 A output, reducing power to prevent overheating until the bank cools.
