The Power Hat is a beneficial idea , but the country of solar panel efficiency is such that this chapeau at least require idealistic weather conditions and an idealistic orientation to convert enough solar energy into electricity to charge your iPhone or other twist in a short amount of time .

Best Prices Today: Solar Hut
Wearing a hat when you ’re spend time in the sun is idealistic to protect your skin and help keep you cool . But why not go a step further and make the hat capable of charge an iPhone ? That ’s the assumption with the EcoFlow Power Hat . It ’s a Dominicus lid with border lined with solar panels . If the conditions are right , it can make solar energy that can be used to charge a fluid gadget , such as an iPhone .
The Power Hat immediately catches the eye . Unlike conventional out-of-door clothing in green , brown , or pastel colors , the hat is black to jibe the opprobrious solar venire . The pitch - black colour and the creases on the brim had led to the somewhat unlooked-for consequences : When try out them on in the power , my co - actor tease me aboutHogwarts – I have to admit , the comparing is not too far - fetched . My fellow travellers on the route associated the facial expression with nineteenth - century fashion . In any case , the hat looks quite strange .
The plastic edge are creased along the photovoltaic element so that the hat can be folded quite comfortably – a clear advantage over classical summertime hats , most of which do not survive the first journey in a dish without optic loss . The edge are made of full-bodied charge plate , with the jury on the upper side and a fabric liner at the bottom , presumably to foreclose excessive perspiration .
Two USB ports for charging cables
The lid weigh just 370 g , and I did n’t have any discomfort during a five - hour hike with the lid either on my head or hanging my cervix with the provide lid strap . Only in unassailable gusts of flatus do the full-bodied plastic brim oppose to a breeze – the wind almost tear the chapeau off my head doubly if it had n’t been secure with the strap .

In size average - orotund ( heavy - special heavy is also uncommitted ) , the brim is 14 centimeters panoptic , so the lid measures around 47 centimeters in diam , more than enough to reliably protect your face from the sun ’s rays , even on a sunny sidereal day in the mountains .
The Power Hat has two USB - A and USB - C interface on the undersurface of the brim .
Can the Power Hat charge an iPhone?
Solar radiation in Oberstdorf on April 6 , 2025

I wore the solar hat on a rise in the Allgäu on April 6 , 2025 , and agree toOberstdorf.de , the solar radiation on that solar day reached 1,000 watts per square meter around midday . It was very sunny with hardly any cloud in the sky .
Solar radiation in Oberstdorf on April 6, 2025
EcoFlow states a maximal current of 2.4 amperes for the Power Hat . When tie to an iPhone 16 and using the USB - ascorbic acid charge cable length ( which supports Power Delivery ) that is included with the phone , and when wearing the hat and connected to the iPhone , the Solar Hat supplied so piddling potential drop that the iPhone recognized a power germ and displayed the charging icon for a curt time . However , the iPhone was not charged ; the percentage display on the battery did not increase . I measured a flow of 0.15 to 0.87 amperes , and the value never exceeded one ampere . The brim of the chapeau has a fairly steep angle when wearing it , but regardless of its position , only a quarter of the rim receive unmediated sunlight . The residual is either in the tone or at such an unfavourable angle that the respective photovoltaic roofing tile does not receive any muscularity .
Here ’s an example of how solar radiation is pass out across the photovoltaic elements . Only the front two get a reasonable amount of energy ; the rest are either in the shade or at an unfavourable slant .
It was only when I took off the chapeau and propagate it out on the basis that I saw a higher amperage ranging from 1 ampere to 1.38 amperes . In this spread - out state , the hat was connected to the iPhone for around 20 minutes , during which the smartphone was charged by six part points , from 43 per cent to 49 per centime . Under such idealistic stipulation , the iPhone could be charged from zero to 100 percentage in over 5 hour .
Here’s an example of how solar radiation is distributed across the photovoltaic elements. Only the front two get a reasonable amount of energy; the rest are either in the shade or at an unfavorable angle.
Should you buy the EcoFlow Power Hat?
The musical theme behind the Power Hat is appeal : while you are out , you benefit from solar energy and apply it to accuse your own machine . However , recitation show that this hat at least call for ideal weather condition conditions and an idealistic predilection in club to convert enough solar vim into electrical energy . As a sunshine hat , however , the solar hat from EcoFlow is almost perfect , it is lightweight and the brim is wide enough to protect the side from the sunlight at most angle . If it were half the price , this would be a clear good word to grease one’s palms , but the combination of a conventional sun hat and a power cant is more affordable .
