Great charging station
Color: Black
I love this charging station. It lives on my desk and it gets used all day every day with every device I can think of charges my phone, my MacBook Pro, my gaming, laptop, headphones, etc and it doesn’t quickly. I’ve had no problems with it whatsoever, and I love the retracting cables, and a little adhesive pad that keeps it in place on the desk. Well done!

retractable cable is a game changer for desk cable management
Color: Black
The retractable cable on this power strip is the feature I didn't know I needed. Being able to extend exactly as much cord as you need and have the rest neatly contained means zero cable clutter on the desk. The 2.3ft cord is enough for most desk setups and the coil retracts cleanly every time.
100W total output is adequate for a multi-device setup — I run a MacBook Pro (via the 65W USB-C port), an iPad, a phone, and a small lamp off it simultaneously without issues. Three AC outlets cover anything that doesn't charge via USB.
The form factor is compact enough that it sits on the desk surface without being in the way. Build quality feels premium, not flimsy. The InstaCord retraction mechanism is smooth and doesn't feel like it'll snap after a few months.
One thing to note: this doesn't have a battery, it's just a power strip with a retractable cord. If you need a battery backup, look elsewhere. As a pure power strip with great cable management, it's excellent.

Awesome desktop accessory!
Color: Black
Perfect desktop accessory for maximum functionality. 3 outlets on the back and 2 USB C cables that come out the sides. Holding to the side via a magnet. Charges my devices very quickly. Absolute workhorse for its weight and portability.

Minimalist's Dream
Color: Black, Color: Black
The ultimate desk decluttering tool!
I am extremely happy with this 7-in-1 station. The best part is the built-in retractable cables; I no longer have to manage a mess of cords on my desk. It has a very small footprint but packs enough punch to power my laptop and several other devices at once. It’s a high-quality, compact solution that solved all my cable management issues. Five stars!
