Great alternative to Anker. Juices up my Steam Deck with no issue and overall is just fantastic. Used it for a plane ride a while back and it was keeping my phone and Deck charged with no issue. It SPEEDS through it's charge though with the 65 watt speed. On a roughly 3 hour flight it was at about 40-30% charge when I was done but my Deck was fully charged. This was also being used while waiting to board when I was still playing. Overall, couldn't ask for much else out of it. The fact that you can charge it with Micro USB, USB C, AND with Lightning is just awesome. Would not recommend using the Lightning as it would take you forever to charge this monster but it's still nice to have as an option.
Don't hesitate on this one! Will update this review if I ever end up with some major issues but so far have not had any. Also works great for charging laptops too. (Do look up on your own if 65W is enough for yours, it's plenty for my work laptop. YMMV)
