Also: 5 gadgets I never travel without (and why they make such a big difference)
Take the Rolling Square Supertiny 65W . Not much bigger than a golf ball, this thing can push out an impressive 65W of power and still be cool to the touch.

Rolling Square Supertiny 65W
The world's smallest 65W GaN USB-C charger, with a design that just makes sense.
I first heard about the Supertiny back when Rolling Square was having a crowdfunder for it, and so confident I was that the product would ship that I actually dropped the coin to get myself a couple (that's rare for me!).
The other day they arrived on schedule – a UK and EU version – and I immediate started testing them.
First impressions of them are that they are solid, dense units. They're the sort of thing that's going to survive being rattled about in a suitcase or bag.
They're super compact and built to the sort of precision that I expect from Rolling Square, a company that designs its stuff in Switzerland and prides itself on quality.
First, the name -- Supertiny. These are tiny chargers. The US version measures 1.7 by 1.37 by 1.37 inches, thanks to the folding prong design, making it ideal for tucking into a shoulder bag, pocket, or backpack.
The ribbing also dissipates heat by increasing the effective surface area of the charger.
The exterior is made from a tough V0 fireproof polymer, and comes with the option for US, UK, and EU plugs on the end (there's no interchangeable version available, which is a shame), and there's one USB-C port -- which has a neat orange accent to make finding the port easier.
Neat orange accent on the USB-C port is a nice touch.
Ribbing on the exterior not only makes it easier to grip the plug but also helps to dissipate heat and make the unit feel cooler to the touch. This is a really clever design that looks good and is practical -- again, something I've come to expect from Rolling Square.
Also: This USB power meter I tested is shockingly accurate - especially for how cheap it is
Internally, the Supertiny uses GaN (gallium nitride) transistors to create a charger that's smaller, more efficient, and cooler than silicon technology, and it supports USB-C Power Delivery (PD) for fast and efficient power transfer, making it compatible with most USB-C devices.
's buying advice
Looking for a small charger that packs a punch? They don't get better than the Rolling Square Supertiny . This is compact yet powerful, tiny yet packing a punch. And no matter whether you're in the US, EU, or UK, there's a version for you. All for $50.
If getting the absolute smallest 65W charger isn't your priority, then a close competitor is Anker's 715 65W charger , which you can get for $27. Anker's version is just as powerful, and has proven to be a worthy accessory for phones, tablets, and more.
