1400mAh power bank? What good is it? No thanks. This reads like a positive review in exchange for free stuff.

5

all in one stuff is a no for me.

It is inherently a flashlight. Power bank feature is something that is needed in an emergency. You only need a few phone calls to be able to solve the problem.
Can you find a good complete, functional product like nextool for such a price.

The iphone 8 has a capacity of 1821 mAh. The battery in this lamp has a higher capacity of 1400mAh, do you know why the power bank is only 1400mAh.

Possibly 2 different capacity measurements.

  • it says the flashlight uses a 2600mAh li-ion battery (3.7v)
  • maybe the 1400mAh is USB output voltage of 5v

so 3.7v * 2600mAh = 9.62Wh
USB is 5v, so 9.62Wh / 5v = 1924mAh, but factor in some losses due to voltage conversion (1400mAh is still a bit far from 1924mAh though). usually maybe 10-20% loss due to conversion, so assuming 20% loss (1924 * 0.80 = 1539mAh usable USB5v capacity?) Well purely extrapolating the data, this guesswork may be totally wrong…
