Since we live in the times of high tech and one of our biggest fears is that our gadgets won’t last through the day, today’s article is about choosing the best solar power bank. As usual, we’ve combed the internet and found the best deals for our readers, so keep reading because you’re in for a real treat.
The thing about solar power banks is that they’re some type of neo- perpeetuum-mobile, i.e. solar-powered stuff enjoys a form of free and (almost) perpetual energy. Well, at least until you drop your solar power bank in the pool, or whatever catastrophic event takes place (like your rechargeable battery dying on you).
Now, since we live in smart world, you’ll definitely require a smart energy solution to keep your phone or your laptop charged while you’re browsing the “interwebz” for cat pictures, and here the solar power bank comes into play, due to its inherent qualities: reliability and efficiency. Okay, there’s also a “coolness” factor embedded in this type of gear, but let’s skip that for the time being.
The concept behind a solar power bank is pretty straight forward: get a high-quality pack of rechargeable batteries, slap a solar charger (a micro solar panel with an inverter and all that jazz) on top of it, and voila: you’ve got endless juice to power up your high-tech paraphernalia. And speaking of mobility and high-tech gear, it makes perfect sense to keep your laptop charged at all times, especially if you’re constantly using an external hard drive or, why not, a travel router.
How to Choose the Best Solar Power Bank
Since solar power banks are the ideal companion for travelers, the best ones are compact and easy to carry around, so look closely at metrics like weight and size. We know, that sounds pretty obvious, and the same stands true for the next issue: size matters. Now, before getting all giddy and giggly on us, no, we’re not thinking about what you’re thinking, but more like capacity matters.
When you go shopping for a solar power bank, make sure you know exactly what you’re hoping to charge with it. To make it simple, the portable charger’s capacity must match (in an ideal world, to exceed) the capacity of the battery of the smartphone or whatever device it’s going to charge. Battery capacity is measured in mAh aka milliamp hours, and the general rule of thumb is that if you want to charge a 3,000 mAh smartphone battery, it would be great to have a solar power bank with at least the same output.
By the way, a 5,000 mAh power bank will only charge a 5,000 mAh battery one time, hence if you want to charge multiple devices, think big (capacity, right?). And since we’re talking about charging batteries, make sure your power bank comes with safety features, like protection of short circuit and protection of overcharge. The former cuts power automatically when a short circuit occurs, while the latter protects the battery from, well, you see where this is going.
Another thing to take into consideration is the specs of the wall charger used for the device you’re going to charge with the power bank. While most smartphones require at least 5 watts/1 amp to charge correctly, more powerful gear like a tablet or a laptop will expect up to 12 watts/2.4 amps. If the solar power bank can’t match that output, you’ll be facing excruciatingly long charging times, and that’s not cool. The idea is to go for a high output power bank to get the juices flowing into your smartphone in the shortest amount of time.
Finally, check out the input/output ports, to make sure they’re enough for your specific needs (the number and type of USB ports for example), and also if they’re rated for the device they’re going to charge. Also, look into “how do I connect my stuff to the solar power bank”, or charging inputs. Remember that fast charging (charging speed is an issue with many people nowadays) is a nice feature to have, but that requires a compatible power bank, a compatible cable and, most importantly, a compatible device.

RAVPower Solar Charger 20000mAh
The Best Solar Power Bank for Camping

To give you a hint about what 25,000mAh looks like in the real world, the GoerTeK is capable of charging an iPhone X seven times before requiring a “refill”.
However, it’s worth mentioning that if you don’t have a 5V/2A adapter and a power supply available, it may take between 3 and 7 days to fully charge the Li-Polymer battery via the solar panel, which is kind of normal for this type of gear. The GoerTeK can charge up to three devices simultaneously, which is very convenient, and it’s built from a tough plastic; and before you ask, that means it will resist wear and tear with flying colors.

Hiluckey Solar Charger 25000mAh

Now, even if we’re talking mainland China tech, this solar charger is very different from your “vanilla” 25k mAh, and that’s due to its smart folding design. While other solar bans make require up to 3-4 days to fully charge if left outside in the sun, due to their small-sized solar panel, the Hiluckey boasts a 4-panel folding design.
More exactly, once unfolded, you’ll benefit from 4 tiny solar panels compared to a regular solar “plant” that only has one, which means this device will self-recharge way more quicker, due to better solar energy conversion.

The Best Budget Solar Power Bank

The thing about the RLERON 24k is that it looks like a regular gadget, missing on the popular ruggedized/outdoorsy finish of its brethren, and maybe that’s why it’s a literal bestseller. Strangely enough, it does feature a LED flashlight, yet there are no outdoors friendly features, such as integrated hanging hooks and whatnot.
