VINSIC 20,000mAh Power Bank Review

The Vinsic 20,000mAh Power Bank is one seriously chunky power bank, and it needs to be given the huge size of the battery.

The power bank comes with a cloth bag to store it in as well as a USB charging cable that is used to charge the power bank and can also be used to charge your mobile or tablet. Note this is a standard USB cable that’s used by Android/Windows mobiles, if you’re an Apple iUser you’ll need to provide your own charging cable.

There is a little readout to show how much charge is left in the power bank, you’ll get a good number of charges out of this (how many will depend on your mobile/tablet battery size).  In the review video below you’ll see a HTC M9 was topped up from 27% to 34% after a 10 minute charge.

VINSIC 20000mAh Smart Identification

Due to the enormous size of the battery this takes a loooong time to charge up, you’ll need to leave this charge at least over night, if not for most of a day as well if charging from close to empty.

The glossy case is something of a fingerprint magnet and it’s very heavy compared to other power banks I’ve tried, but it also provide a huge amount of power to charge your devices so is perfect for those worried about being away from a plug socket for a few days.

  1. I recently bought a similar model: Vinsic VSPB303. The main difference is that one of the USB ports is QC3.0, and there is a USB Type C connector.
    Thing is, it charges my Huawei P9 Plus only twice, after which the bank indicator shows 8% charge left. Per online specs, the P9+ has a 3400mAh battery. Assuming a very bad charge efficiency of 70%, math shows that the battery capacity is near 1000mAh, and not 20000mAh.
    I therefore want to take a look under the hood to check out the battery. However, I can’t get it open without using dangerous force.
    Is there a teardown of this power bank somewhere? I can’t seem to find a teardown other than for the Slim, which is very different.
