The Choetech 24W portable solar panel USB charger shows what you can achieve when an enterprising group focuses on making a quality USB power delivery solar panel charger.

Review: Choetech 24W portable solar panel USB charger

This Choetech 24W portable solar panel is a foldable four-panel cell for hikers, campers and beachgoers. It is not meant for fixed installation, but it is IP65 weather-resistant so you can use it in the rain. It uses PET laminated solar panels with high-wear welded PVC fabric.

First, it uses 24% efficiency monocrystalline silicon cells that are well above the portable solar panels that seem to range from 10-15% for the much cheaper thin-film and polycrystalline silicon panels.

Next it has the smarts to deliver either regulated 2 x 5V/2.4A (24W) outputs at the same time or one up to 5V/4A (20W) for a quick charge.

The Choetech 24W portable solar panel charger has

  • 2 x 5V/2.4A ports (or one x 5V/4A) via smart IC chip regulation that detects USB pin signals and prevents overcharging. LED indicator.
  • iPhone 7.5W compatible for iPhone 8 and later
  • Samsung Galaxy compatible for 15W for faster charging (USB PD 1.0 5V/3A compatible)
  • Charges any micro-USB or earlier Lightning device (BC 1.2, 5V and up to 5A draw compatible)
  • Size: Folded 260 x 160 x 40mm or unfolded 790 x 260 x 20mm x approx. 500g
  • Has an integrated mini-pouch for cables or a phone
  • Comes with a lightweight foldable backpack for use while walking
  • Comes with four carabiner clips for easy mounting
  • Is IP65 rated

It is well made, edges are nicely sealed, and the quality is evident.

Tests

Our test was over three days (8-10 hours) in good summer sun conditions. Mostly it sat flat on an east facing table until lunchtime and then to a west facing ledge and slightly angled to catch the sun. Naturally, charging ability depends on capturing the most available sunlight.

  • When charging an empty 5200mAh security camera battery (camera working as well) it took just eight hours.
  • It fast charged an empty 10,000mAh power battery bank in the just over six hours.
  • It fully charged two working smartphones (both with 4,000mAh batteries) in just over six hours.

OK these times are about twice as long as a 240V plug-in charger but the power is free!

GadgetGuy’s take: Choetech 24W portable solar panel provides excellent USB power

One caveat – it only works during sunlight hours and being a flat panel, you need to occasionally re-orient it towards the ever-changing angle of the sun.

If you marry this with a 20000+mAh USB-C Power Bank you have the means to run your USB-C/Thunderbolt laptop, 4000mAh smartphone and other USB devices day or night. In fact, I suspect if you use the battery in circuit all the time it would be a better combination as the battery has USB-C PD 2.0 outputs.

I see not only cyclists, campers and hikers et al using it but on construction sites and remote locations to top up the battery bank. I can’t vouch for 365-day use as it is a portable device, but it looks like it would last.

For what it is – it is a 10-out-of-10. And it shows that an efficient solar panel charger costs the same or less than many other name brands!
