Compact 10000mAh Power Bank for Daily Carry
The INIU P55 stores 10000mAh of lithium-polymer energy in a black chassis measuring 4.4 by .7 by 2.7 inches. Two bidirectional USB-C ports and one USB-A port let you charge three devices at once. It is built for travellers and commuters who need a pocket-sized reserve without the bulk of larger packs.
Thermals and Power in Normal Use
TempGuard 2.0 technology monitors temperature 3.2 million times per day to keep cells within safe limits. The unit delivers up to 45W through Power Delivery and Quick Charge protocols while maintaining a 12V 3A output profile. No active cooling is required and operation stays silent during typical phone or tablet charging sessions.
45W USB-C Output Decides Compatibility
The single specification that determines fit is the 45W maximum USB-C Power Delivery output. It will fast-charge recent iPhone and Samsung flagships at or near their peak wired speeds. Buyers whose laptop or tablet demands 60W or 100W over USB-C should look for a higher-wattage bank instead.

Questions about this item
How do I use the attached USB-C cable to charge the power bank itself?
Plug the attached nylon-braided USB-C cable into either of the two bidirectional USB-C ports on the INIU P55 and connect the other end to a USB-C charger; the same cable works for both input and output.
What capacity loss should I expect over time with the 10000mAh lithium-polymer cells?
The supplier notes that 30–40% of rated capacity is lost to circuit heat and voltage conversion, so a fully charged unit delivers 6000–7000mAh to devices; plan replacement when delivered capacity falls below your needs.
At what point does the 45W output throttle during sustained charging?
The built-in TempGuard 2.0 system monitors temperature 3.2 million times per day and will reduce power output to keep the power bank within safe thermal limits.
