Ecoflow Power Hat Review: A Sun Hat with Solar Cell Panels

Wearing a hat when you spend time in the sun is ideal for protecting your skin and helping keep you cool. But why not go a step further and enable the hat to charge an iPhone? That’s the prerequisite of Ecoflow Power Hat. It is a sun hat with edges lined with solar panels. If conditions are correct, it can create solar energy that can be used to charge a mobile device such as an iPhone.

The power hat immediately catches the eye. Unlike conventional outdoor clothing in green, brown or pastel colors, the hat is black to match the black solar panels. The pitch-black color and the folds on the rim had led to the somewhat unforeseen consequences: When I tried them in the office, my colleagues teased me if Hogwarts I have to admit, the comparison is not too long. My fellow travelers on the route connected the look of the 19th century fashion. In any case, the hat looks quite unusual.

The plastic edges are folded along the photovoltaic elements so that the hat can be folded quite comfortably – a clear advantage over classic summer hats, most of which do not survive the first journey in a bag without visual loss. The edges are made of sturdy plastic, with the panels on the upper side and a fabric lining at the bottom, presumably to prevent excessive sweat.

The hat weighs only 370 grams and I had no discomfort during a five -hour hike with the hat either on my head or hangs my neck with the included hat strap. Only in strong wind throw do the sturdy plastic stimulants respond to a play – the wind almost tore the hat from the head twice if it had not been fastened with the strap.

In size Medium-Stor (large-Extra large is also available), the rim is 14 centimeters wide, so the hat measures about 47 centimeters in diameter, more than enough to reliably protect your face from the sun’s rays, even on a sunny day in the mountains.

Power Hat has two USB-A and USB-C ports on the underside of the rim.

Can Power Hat Charge an iPhone?

I wore the sun hat on a hike in Allgäu on April 6, 2025, and according to Oberstdorf.de the solar radiation reached 1,000 watts per day. Square feet around noon. It was very sunny with barely any clouds in the sky.

Ecoflow indicates a maximum current of 2.4 Amps to the power hat. When you are connected to an iPhone 16 and use the USB-C charging cable (which supports power supply), which is included on the phone and when you carry the hat and connect the iPhone, the sun hat provided so little voltage that the iPhone recognized a power source and showed the charging icon for a short time. However, the iPhone was not charged; The percentage of battery did not increase. I measured a stream of 0.15 to 0.87 amps and the value never exceeded an ampere. The hat of the hat has a rather steep angle when it carries it, but regardless of its position, only a quarter of the rim got direct sunlight. The rest is either in the shade or at such an unfavorable angle that the respective photovoltaic tile does not receive energy.

It was only when I took off the hat and spread it out on the ground that I saw a higher current from 1 Amps to 1.38 Ampere. In this scattered state, the hat was connected to iPhone for approx. 20 minutes in which the smartphone was charged by six percentage points, from 43 percent to 49 percent. Under such ideal conditions, the iPhone could be charged from zero to 100 percent in over 5 hours.

Should you buy Ecoflow Power Hat?

The idea behind the power hat is appealing: While you are out, you benefit from solar energy and use it to charge your own devices. However, practice shows that this hat at least requires ideal weather conditions and an ideal orientation to convert enough solar energy into electricity. Like a sun hat, however, the sun hat from Ecoflow is almost perfect, it is light, and the rim is wide enough to protect the face from the sun at most angles. If it was half the price, this would be a clear recommendation to buy, but the combination of a conventional sun hat and a force bank is more affordable.
