    Purchased this as my charger block died. I am impressed with Anker products as this charging block is very well made, small yet powerful. The 30W output charges my Samsung S24 from 10 to 80% in less than 30 minutes!

    The Anker Eco Nano Power Brick is hands down one of the best power adapters I’ve used. I was blown away by how small and lightweight it is—seriously, it’s no bigger than a quarter, so it takes up no space in your bag or pocket. Despite its size, it delivers solid power, charging my devices quickly and efficiently without overheating. It’s perfect for travel or just keeping your setup minimal and clutter-free. Plus, knowing it’s part of Anker’s eco-friendly lineup is a nice bonus. If you want something compact, reliable, and powerful, this is a no-brainer.

    Got it for an emergency brick good enough to charge my laptop. does the job well enough. laptop takes 25w to run, this sends 30. doesn't charge laptop fast, but if you need a cheap lifeline, any 30w PD charger will do. this will keep an HP envy on and charging. great for phones. highly recommend for phones. IQ means it supports Samsung blue charge, PD (the generic one both apple and samsung should really be using, your windows laptop probably uses this) , and whatever apple uses. one con: the outlet plug flip can buckle against childproof outlets. the Insignia one i got has all these advantages and a stiffer outlet flip. you can account for this, its only a minor inconvenience; don't let it stop you from buying this product.

    Purchased this 30W charger as part of a sale that included a 67W Anker charger as well. Two great chargers for $25. I like the compact size for travel and at 30W it's more than enough to fast charge my phone or iPad.
