Sporting a hat if you’re spending time within the solar is good to guard your pores and skin and assist maintain you cool. However why not go a step additional and make the hat able to charging an iPhone? That’s the premise with the EcoFlow Energy Hat. It’s a solar hat with edges lined with photo voltaic panels. If the situations are proper, it will probably create photo voltaic power that can be utilized to cost a cellular gadget, akin to an iPhone.
The Energy Hat instantly catches the attention. Not like typical out of doors clothes in inexperienced, brown, or pastel colours, the hat is black to match the black photo voltaic panels. The pitch-black coloration and the creases on the brim had led to the considerably unexpected penalties: When attempting them on within the workplace, my co-workers teased me about Hogwarts–I’ve to confess, the comparability shouldn’t be too far-fetched. My fellow travellers on the route related the look with Nineteenth-century vogue. In any case, the hat appears to be like fairly uncommon.
The plastic edges are creased alongside the photovoltaic parts in order that the hat will be folded fairly comfortably–a transparent benefit over basic summer time hats, most of which don’t survive the primary journey in a bag with out visible loss. The perimeters are made of strong plastic, with the panels on the higher facet and a cloth lining on the backside, presumably to stop extreme perspiration.
The hat weighs simply 370 grams, and I didn’t have any discomfort throughout a five-hour hike with the hat both on my head or hanging my neck with the supplied hat strap. Solely in sturdy gusts of wind do the sturdy plastic brims react to a breeze–the wind nearly tore the hat off my head twice if it hadn’t been secured with the strap.
In dimension Medium-Massive (Massive-Additional Massive can also be out there), the brim is 14 centimeters large, so the hat measures round 47 centimeters in diameter, greater than sufficient to reliably shield your face from the solar’s rays, even on a sunny day within the mountains.
The Energy Hat has two USB-A and USB-C ports on the underside of the brim.
Can the Energy Hat cost an iPhone?

Photo voltaic radiation in Oberstdorf on April 6, 2025

I wore the photo voltaic hat on a hike within the Allgäu on April 6, 2025, and in response to Oberstdorf.de, the photo voltaic radiation on that day reached 1,000 watts per sq. meter round noon. It was very sunny with hardly any clouds within the sky.
EcoFlow states a most present of two.4 amperes for the Energy Hat. When related to an iPhone 16 and utilizing the USB-C charging cable (which helps Energy Supply) that’s included with the cellphone, and when sporting the hat and related to the iPhone, the Photo voltaic Hat equipped so little voltage that the iPhone acknowledged an influence supply and displayed the charging icon for a short while. Nevertheless, the iPhone was not charged; the share show on the battery didn’t enhance. I measured a present of 0.15 to 0.87 amperes, and the worth by no means exceeded one ampere. The brim of the hat has a reasonably steep angle when sporting it, however no matter its place, solely 1 / 4 of the brim obtained direct daylight. The remainder is both within the shade or at such an unfavorable angle that the respective photovoltaic tile doesn’t obtain any power.

Right here’s an instance of how photo voltaic radiation is distributed throughout the photovoltaic parts. Solely the entrance two get an affordable quantity of power; the remaining are both within the shade or at an unfavorable angle.

It was solely after I took off the hat and unfold it out on the bottom that I noticed the next amperage starting from 1 ampere to 1.38 amperes. On this spread-out state, the hat was related to the iPhone for round 20 minutes, throughout which the smartphone was charged by six proportion factors, from 43 per cent to 49 per cent. Underneath such preferrred situations, the iPhone could possibly be charged from zero to 100% in over 5 hours.
Must you purchase the EcoFlow Energy Hat?
The concept behind the Energy Hat is interesting: while you’re out, you profit from photo voltaic power and use it to cost your individual units. Nevertheless, apply reveals that this hat a minimum of requires preferrred climate situations and a super orientation so as to convert sufficient photo voltaic power into electrical energy. As a solar hat, nevertheless, the photo voltaic hat from EcoFlow is sort of good, it’s light-weight and the brim is large sufficient to guard the face from the solar at most angles. If it had been half the worth, this could be a transparent suggestion to purchase, however the mixture of a standard solar hat and an influence financial institution is extra inexpensive.
