Why Did My Laptop Charge Very Slowly with My Phone on My Gan Charger?

I plugged my phone and laptop into my new GaN charger expecting fast speeds for both. Instead, my laptop charged at a crawl, and I was left frustrated and confused.

Do I Need a Real Compass for Navigation Instead of My Foldable Solar Panel’s?

by Bernard Ryan

I used to think the compass on my foldable solar panel was good enough for hiking. It turns out that little magnetic sensor can lead you astray when you need direction most. That built-in compass is often just a cheap digital sensor affected by the panel’s own electrical current. In my experience, a real magnetic … Read more

If your solar charge controller keeps showing error codes or shutting down, the fix might be as simple as changing how you mount it. Mounting it vertically is not a suggestion, but a key requirement for proper cooling and reliable operation. Most charge controllers use natural convection to cool their internal components. When mounted flat, … Read more

A dead or bad charge controller can leave you stranded without power for your phone or GPS. If your solar or wind controller has failed, you need a safe backup plan to keep your devices running. Many boaters don’t realize their outboard motor’s alternator or a simple battery-to-battery charger can bypass a faulty controller. I … Read more

Why Am I Not Happy with My Solar Charge Controller Dying so Early?

by Bernard Ryan

I was frustrated when my solar charge controller failed after just two years. You probably feel the same way if your system stopped working way too soon.

Why is My Gan USB Charger Not Providing the Full 100W it Advertised?

by Bernard Ryan

You plug in your new GaN charger expecting 100W of power, but your laptop charges slowly. This is frustrating, and it happens more often than you might think. The advertised 100W is only possible under perfect conditions with the right cable and device. Real-world factors like heat, cable quality, and multiple ports all cut into … Read more

Is My Foldable Solar Panel Cheap Because the Quality is Poor?

by Bernard Ryan

You bought a cheap foldable solar panel and now you’re worried the quality is terrible. I get it — we all want gear that works without draining our bank accounts.

Why Does the Coil Whine on My Gan USB Charger Get Louder when I Plug in Devices?

by Bernard Ryan

You plug a device into your GaN charger, and suddenly that faint hum becomes a noticeable whine. This coil whine getting louder is a common annoyance that makes you wonder if your expensive charger is breaking. This noise isn’t usually a sign of failure but rather a physical reaction to increased electrical stress. The higher … Read more

Why Was One Unit of My Foldable Solar Panel Defective Right Out of the Box?

by Bernard Ryan

You just unboxed a brand new foldable solar panel, but one unit won’t charge. It is frustrating when expensive gear fails before you even use it.
