    The Best Portable Solar Charger Reviewed by Wirecutter


    " The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and it has unique features that make it more versatile and durable, including three output ports (versus two on most other chargers), and an expansive but lightweight array of panels to catch every last ray of sunlight. Smaller and lighter than other options with similar output, so it can more easily fit into a camping backpack, hiking daypack, or emergency kit." -- By Wirecutter Editor

    Operating Temperature 14 ℉-158℉
    USB-A Output 3* 5V/2.4A Max, 5V/4.8A Max in Total

    This solar charger can charge my cellphones at night?

    No, this portable solar charger can't store the electricity, you need to connect your device to the solar panel in direct sunlight outdoors.

    Why the real output is different from the power claimed?

    This product has 4 piece panel, each is 7w, so the power is 4*7w=28W; Theoretical output is 5V/2.4A Max for each port, 5V/4.8A Max in total, the total theoretical power is 5V*4.8A=24W Max. But there are loss in the solar energy conversion process.

    What's the auto-restart function?

    Any cloud or covering arrives may knock the value of output down, but this folding solar panel charger can automatically recover to normal charging speed when there are enough sunlight.

    This solar charger can charge Androids and Apple cellphones?

    Yes, but our solar phone charger doesn't include the lightning cable for iPhone or iPad.

    What does the red indicator mean?

    The red LED light will go on when the solar panels works normally; It will flicker when there are overcurrent or short circuit.

    5.0 out of 5 stars Quick multi-unit charging panel- great in the sun, adequate in cloudy weather
    Reviewed in Canada on August 2, 2023
    I recently went on a two week remote fly-in kayaking trip and needed to get a solar charger for various devices. Of course, it's always a trade off between function, cost and weight. This showed up on gearlabs webpage as the "best choice" and after reading reviews for awhile I gave it a go. Unfortunately, as you can see, there was significant smoke cover for most of our trip, as such it became clear it charges small devices very quickly in the light (iphone, watch, petzyl headlamp battery, most importantly garmin inreach), fairly quickly in the shade. But it had a hard time charging my bose waterproof speaker and the battery packs I brought with. But given the smoke, they would probably have taken a fair bit less time in full light (8-10hr for full charge in smoke). But we had occasional rest days and pulled out the charger at every paddling break and meal so we could make sure our emergency devices were charged. I hadn't read fully about the waterproofing at the attachment sites so I didn't test it while paddling or in the rain (see my drytop wrapped around the attachment ports when expecting rain). My paddling partner brought in a smaller device that wasn't as fast with charging, did have multiple attachments but the cables were fixed so you couldn't have two micros or two USB C at the same time (whereas this has 3 USB ports for any combination of attachments). Overall, I love this charger. It's weightier than I'd like on a backpacking trip but for long distance outdoor events when you're bringing bigger volumes, this is at the top of my pile. And I'm looking forward to using it in skies that aren't under smoke weather warnings and evacuations....
