NIGHT while sleeping, thus safety is a concern as low grade power cells
can be explosive based if over-charged. The current market today as we

uncertified safety measures, so it is advisable that user give a thinker
to opt for PowerBank using 1st tier high grade Lithium-Polymer battery
due to its stable elements and safety assurance as long as it is
affordable. After all, the last thing we want is a PowerBank to explode
during usage and charging as we are sleeping. YES, don’t be surprised

port compare to a USB wall charger adaptor eventhough both supply 5V?

This
is due to the USB Port ( USB 2.0 ) in a computer/laptop only supplies
0.5Ampere and a USB wall charger adaptor supplies 1 Ampere to 2.1Ampere
power supply. A Powerbank in general will require 5V/1A for optimum
charging period.

mAh
is short for milliAmpere/hours. It's a measurement of the amount of
energy the battery can store. The one with 8400mAh can store double the
amount of energy that the one with 4200mAh can store.
