Like many middle-aged males, I sport a outstanding solar-powered space on prime of my head — in any other case referred to as a bald spot. Depart it uncovered throughout yard work too lengthy, and it transforms right into a glowing purple beacon by dusk. I’ve realized to put on a hat, however all that prime photo voltaic vitality bouncing off my scalp appeared like such a waste — till I found the EcoFlow Power Ha, a mixture solar hat and solar energy supply that retails for $129 (presently on sale for $99).
The idea is intelligent: eight photo voltaic panels constructed into the hat feed energy to 2 USB ports (one USB-A, one USB-C) housed in a small field beneath the again rim, full with a tiny LED indicator. In observe, nonetheless, the outcomes have been disappointing. Whereas it did an sufficient job defending my scalp from the solar, it barely charged my cellphone in any respect. And maybe most damningly, it is an unsightly hat—the type of factor that solves an issue no one requested about whereas creating a number of new ones.

Design: The least enticing hat I’ve ever worn
There are eight tiny photo voltaic panels within the brim, however except the solar is hitting them excellent, you are not going to get a lot energy out of them.
If I wasn’t already clear: This can be a really ugly hat. Solar hats will not be usually fashionable however this factor seems like a melted flower pot or like an enormous model of a kind of terrible flower pot holders constructed from vinyl data. I am no fashionista however the Oasis reunion made bucket hats cool again and wider-brimmed hats just like the Tilley TS1 preserve the solar off with out wanting such as you’ve been whacked, Wile E. Coyote type, by a falling satellite tv for pc dish. I am a giant fan of practicality over type, however there are limits, particularly as it is not very sensible.
Not straightforward to scrub or put on
All the electronics within the hat imply that you may’t wash it. When my baseball cap will get grubby, sweaty and coated within the soil of exhausting labor, I can throw it within the wash. Strive that with the EcoFlow Energy Hat and you may destroy it. You additionally must have a cable connecting the hat to the cellphone, which is not very sensible if you find yourself attempting to dig out weeds. I ended up operating a cable down the again of my shirt, which simply made the entire thing look much more silly.
Charging: Cannot actually cost something price utilizing
A six-hour gardening session barely moved the needle in charging my gadgets.
The issue is how solar energy works. Light from the sun hits a solar panel, which converts it into electrical energy. That is known as the photoelectric impact, first defined by Albert Einstein, who received the Nobel Prize for figuring it out in 1921. The quantity of vitality will depend on the scale of the panel and the way a lot mild hits it. That, in flip, will depend on how the panel is positioned relative to the solar.
That is why the photo voltaic panels in your roof are tilted south to face the solar. The EcoFlow Energy Hat options eight small photo voltaic panels positioned round its giant brim. That signifies that most do not get a lot, or any, direct mild except the solar is straight overhead. The solar has an annoying behavior of rising and falling, so more often than not, you are not getting a constant quantity of direct daylight.
What does all that imply in sensible phrases? It means this photo voltaic hat does not work very nicely. I examined the hat within the full noon solar in my yard close to Boston and located that, at finest, it generated about 5 watts of energy; that is not quite a bit. It generated 5 volts on the USB port, however the present circulate by no means exceeded 1 amp, that means it was nonetheless solely producing about 5 watts of energy. Within the morning or afternoon, when the solar was at a sure angle, the present generated fell to lower than 0.3 amps, roughly 2 watts. EcoFlow claims it will possibly generate as much as 12 watts however I by no means managed something close to that.
100 hours to cost an iPhone 17 Professional
To check it additional, I carried out an arduous gardening session. Effectively, okay, I caught it on a pole, related it to a hefty portable power bank and watched from the deck to ensure my native groundhog (we name him Wilbur the Whistle Pig) did not steal it. After six hours of this backbreaking work, the cost stage had elevated by 9%, representing about 225 mAh of saved cost. That is about 5% of the capability of an iPhone 17 Pro, so this hat would take about 100 hours to cost the cellphone. That is assuming the cellphone just isn’t operating on the time.
The Energy Hat wants 100 hours to cost an iPhone 17 Professional, if the cellphone is off.

Shopping for recommendation: Skip, there are higher hats and higher photo voltaic charging choices on the market
Lots of the merchandise I check find yourself being a case of a fantastic thought however poor execution. The practicalities of producing merchandise and the compromises of real-world engineering usually undermine the meant objective of the product. Nonetheless, at $129 full value or $99 on sale if you happen to buy direct from EcoFlow, EcoFlow Energy Hat is among the uncommon exceptions that may be a unhealthy thought with unhealthy execution.
It is ugly and has photo voltaic panels which might be too small to be efficient for, nicely, something. It is perhaps higher in the event that they went with a flat cap design, or a sahara or hiking hat design with the photo voltaic panels on the highest or neck flap as an alternative. It is also an inferior answer to easily getting a fast and compact portable charger, just like the InfinityLab InstaGo 5000 or Anker 523 PowerCore Slim 10K PD. One other various is utilizing a bigger portable solar panel, which you’ll pair with a power station or connect to your backpack as you hike to cost your gadgets, as with the Bluetti Handsfree 2.
All of those choices will offer you extra energy than the EcoFlow Photo voltaic Hat, and so they’ll do it higher and quicker. So preserve the photo voltaic panels off your head and stick ’em on your roof instead.
