Perfectly functional power banks with slight visual imperfections.
These would either be
1. A blemish on the casing which is visible from certain angles in the light
2. the indicator lights aren’t as bright due to not being perfectly aligned
All our power banks as tested personally to ensure they are in perfect working order. However on occasion, we have a few visual impairments caused by errors in production. These are provided at a discount due to that error.
