Anker PowerCore - Banque d'alimentation - 20000 mAh - 2 ports de sortie (24 broches USB-C) - noir

This bulky battery pack failed to impress and is a bit on the pricey side

My biggest complaint with this charger is that you cannot see if it is actually charging without looking at the very tiny lights inconveniently located on the bottom of the front face. I've had this brand before but not this model and my other one had a very large readout on the that displayed the remaining charger life as well as telling you it was operating. This one is very, very difficult to see if it is actually on and charging. That's a huge negative for any devices that are 'touchy' and don't always take a charge.

It does fast charging and it lasts for a long time which is great. It's heavier than expected but very small and slim.

Liked the product but it’s a bit heave. Has good charging power but takes an extreme Amount of time to recharge the pack itself .

This is a great backup power source/battery to charge you phones and tablets while traveling, camping or in a grid down situation (which we had here in Tx a few months ago during the 2021 freeze). I have used it to charge my iPhone 11 and iPad from about 50%, and no name bluetooth headphones from dead and it used less than half of its charge. It recharged relatively quickly with the USB charging port but unfortunately that is a one way port and for charging only and cannot be used to charge other devices (so a no go for a Macbook Air unfortunately). That is my biggest gripe with this. It seems to keep the charge very well when sitting for a long period in storage as well as I had it sitting for over a month and it still read full charge. Time will tell how it lasts (my last Anker 13k battery is still going strong 4+ years later). I will update if needed.
