This is a perfect travel charger. Not sure what you mean. Its not something you put in your pocket on the bus while you travel to work. Its the kind you put in your rucksack/backpack and pull out while on the train etc. The size is smaller than many others which are considered "travel chargers"
I don't like carrying chargers at all, I use samsung phones, I have a 25W (maximum charging rate for samsung phones) charger in my bedroom, another one in my office, and I also have a wireless charger in my desk setup at home, so I don't carry chargers at all, they're all fixed in place if I visit someone I either make sure to charge my phone before going out or I ask to borrow their charger once I'm there.
Wen I do need to carry a charger with me I make sure to go with your common included-with-your-phone wall charger like any of the 25W samsung chargers I have, that's becasue I can separate the cable from the charger and carry both in an ideal manner, preventing damage to my cable and to my charger. Usually people that have broken cables near the termination get that by throwing the charger with cable attached into their backpack, then multiple other things on top of it creating pressure and over time damaging the cable or even the port on the charger, or they use their phone while plugged and keep pulling on the cord. By separating both you can neatly store the cable in a pocket or somehow avoid it being under stress when restriced by the charger port.
This one is a 40W charger so I'm not considering it a laptop charger as I'd only consider a laptop charger at 65W+, also it has a permanently attached power cord which means you cannot separate them and thus it will likely be under stress if you carry it in a bakcpack causing damage, it's also a charger with a wide body design and multiple outputs so really I'd buy it to plug somewhere beneath my desk and them run it over to the top of my desk and glue it there with double-sided tape, there I'd use it to charge any number of things like my smartphone, smartwatch, headphones, earbuds, etc. really a charger with built-in wall plug and a female USB conector is by far the best to travel, it will be even more compact, won't require you to store a 1m cord along with it in the same pocket, etc. So those are the ones I tend to travel with, and you can get those with like 65W+ I've seen some nearing 100W if you really need that, they are quite larger than my 25W samsung charger but still pretty compact while avoiding issues with the cable and still using less space in your bag or backpack because less cables, as cables also do fill space.
