Ultra Compact 2200 mAh Power Bank
This pocket-sized power bank delivers 2200 mAh of backup capacity for smartphones and small USB devices. It suits commuters and travellers who need a lightweight emergency charge without carrying a bulky unit. The blue finish adds a simple colour accent to everyday carry.
Thermals Noise and Power Draw
The unit charges at 5 V and 1000 mA through a Micro USB input and supplies the same 5 V 1000 mA rate via its USB-A output. Passive cooling keeps operation silent during both charging and discharging cycles. Low current draw means minimal heat buildup in normal use.
Single Deciding Specification
The 2200 mAh capacity provides roughly one partial phone charge, so buyers who need multiple full recharges between wall outlets should consider a higher-capacity model. The Micro USB input and USB-A output limit compatibility to devices using those legacy connectors. No fast-charging protocols are supported.

Questions about this item
How do I charge this power bank using its Micro USB input, and what mistake should I avoid?
Plug a 5 V / 1000 mA source into the Micro USB port; using a higher-current charger will not speed up the 2200 mAh recharge.
What part will need replacement first on this 2200 mAh unit?
The internal lithium cell degrades after several hundred cycles; when it no longer holds a useful charge, replace the whole power bank.
What output limit appears first during continuous use of the USB-A port?
The 5 V / 1000 mA output caps sustained current, so devices drawing more will charge at 1000 mA maximum.
