Our verdict
The power hat is a good idea, but the state of the effectiveness of the solar panel is such that this hat requires at least ideal weather conditions and an ideal orientation to convert enough solar energy to electricity to load your iPhone or another device in a short time.

Wearing a hat when you spend time in the sun is ideal for protecting your skin and helping you keep cool. But why not go further and make the hat capable of loading an iPhone? It is the premise with the Ecoflow Power hat. It is a sun hat with edges bordered by solar panels. If the conditions are good, it can create solar energy that can be used to load a mobile device, such as an iPhone.
The power hat immediately attracts attention. Unlike conventional exterior clothes in green, brown or pastel colors, the hat is black to match black solar panels. The black color and the folds to the brim have led to the somewhat unforeseen consequences: when I try them in the office, my colleagues teased me about Hogwarts – I must admit that the comparison is not too bewildered. My traveler colleagues on the route associated the 19th century fashion look. In any case, the hat looks quite unusual.
The plastic edges are struck along the photovoltaic elements so that the hat can be folded fairly comfortably – a clear advantage on the classic summer hats, most of which do not survive the first trip to a bag without visual loss. The edges are in robust plastic, with the panels on the upper side and a lining in fabric at the bottom, probably to avoid excessive sweating.
The hat weighs only 370 grams, and I had no discomfort during a five -hour hike with the hat on my head or suspended my neck with the strap of the hat provided. It is only in strong gusts of wind that the robust plastic edges react to a breeze – the wind almost torn the hat of my head twice if it had not been fixed with the strap.

In average size, the large large is also available), the edge measures 14 centimeters wide, so the hat is approximately 47 centimeters in diameter, more than sufficient to reliably protect your face from the sun's rays, even on a sunny day in the mountains.
The power hat has two USB-A and USB-C ports on the underside.
Can the power hat have an iPhone?
Solar radiation in Oberstdorf on April 6, 2025
HALYNA KUBIV
I wore the solar hat during a hike in the Allgäu on April 6, 2025, and according to Oberstdorf.de, the solar radiation that day reached 1,000 watts per square meter around noon. It was very sunny with almost no cloud in the sky.
Ecoflow indicates a maximum current of 2.4 amps for the power hat. When connected to an iPhone 16 and using the USB-C load cable (which supports power delivery) which is included with the phone, and when wearing the hat and connected to the iPhone, the solar hat provided so little voltage that the iPhone has recognized a power source and displayed the charging icon for a short time. However, the iPhone was not billed; The battery display percentage has not increased. I measured a current of 0.15 to 0.87 amps, and the value has never exceeded an ampère. The edge of the hat has a fairly steep angle when it wears it, but whatever its position, only a quarter of the edge received the direct sunlight. The rest is either in the shade or at an angle as unfavorable as the respective photovoltaic tile receives no energy.
Here is an example of how solar radiation is distributed through photovoltaic elements. Only the two fronts get a reasonable amount of energy; The others are either in the shade or at an unfavorable angle.
HALYNA KUBIV
It is only when I removed the hat and spread it on the ground that I saw an higher ampérage ranging from 1 amps to 1.38 amps. In this broadcast state, the hat was connected to the iPhone for about 20 minutes, during which the smartphone was billed by six percentage points, from 43% to 49%. Under such ideal conditions, the iPhone could be 100% zero in more than 5 hours.
Should you buy the Ecoflow Power hat?
The idea behind the power hat is attractive: while you are absent, you benefit from solar energy and use it to load your own devices. However, the practice shows that this hat requires at least ideal weather conditions and an ideal orientation in order to convert enough solar energy into electricity. As a sun hat, however, Ecoflow's solar hat is almost perfect, it is light and the edge is wide enough to protect the sun in most angles. If it were half the price, it would be a clear recommendation to buy, but the combination of a conventional sun hat and an electricity bank is more affordable.
