Also: The 5 best solar lanterns of 2023 Alternatively, solar lanterns and battery packs may not charge properly if the weather isn’t ideal. Your best bet is to invest in a portable solar charger made of panels that can do the job quickly and effectively. But which panel is the best? It’s helpful to understand how electricity works before you begin shopping. Also: The 5 best camping chairs of 2023 Many people use the analogy of piped water: Think of voltage as water pressure and amperage as the size of the pipe. Electricity generation depends on both voltage and amperage, so solar chargers are evaluated by multiplying voltage and amperage, which gives you the ‘wattage’ advertised on solar panels. In other words, if a charger collectively puts out 5 Volts via one 2.4 Amp USB, it generates 12 watts of power. We looked at panels that range between 15 and 28 watts and that offer enough power without added bulkiness. Also: The best car gadgets, according to auto and tech experts But even in bright sunlight, most panels don’t reach advertised levels of volts and therefore watts. Plus, some devices always charge at lower amps. Some portable chargers can function in any weather, while others go into a tailspin when clouds hover overhead and then fail to reconnect afterward. Size and weight are also key factors to consider while you shop for a portable charger. I analyzed the market to find you the best portable solar charger for your budget and needs. This portable solar charger ensures your devices stay juiced while you enjoy camping, hiking, and more. It features smart IC chip technology, which recognizes which device(s) you’re charging and adapts currents to maximize charging speeds – its speed is similar to a wall charger. The compact, foldable design makes it convenient for travel. The solar charger weighs under two pounds, and with its ETFE construction, it’s more than capable of handling your rugged adventures. Best of all, it works with any device using USB for charging. It means iPads, iPhones, Samsung, and Google devices will all work with this charger. It comes with a 12-month, hassle-free warranty to offer you peace of mind and protection. It may be a sheer coincidence that the most dependable but oversized panel on this list (BigBlue) is also the nickname for one of the most dependable but gigantic technology companies in the world (IBM). Just as IBM burnished its reputation in personal computing, BigBlue has quickly become the de facto benchmark in the sub-30W solar panel universe. This solar charger is heavy, considering it has 4 panels hooked up to 3 USB ports. It’s not as fast as Anker’s charger, but customer reviews rave about the device’s impeccable reliability and ability to charge devices in all sorts of weather. For cloudy conditions, this solar charger is the absolute king. Plus, it features a stellar auto-restart function, which allows it to reboot after cloud interruption. Hardy PET polymer panels and canvas material make it durable, while rubber gaskets protect USB ports from water. When you factor in the newly reduced $58 price tag, the excellent features of this device may outweigh its hefty design. It can also offer you a feeling of quiet confidence in the middle of nowhere, armed with the most reliable power source that money can buy. Ryno Tuff is the ’little powerhouse that can’ on this list. It punches above its weight when it comes to charging speed. Testers say that Ryno Tuff’s 3 panels deliver consistent output quickly in bright sunlight. It can charge your phone up to 33% in just 30 minutes via the two USB ports. Plus, The Ryno Tuff can even charge two phones at once, which most panels can’t successfully do. The supercharger’s only Achilles’ heel? It begins to stutter when clouds roll overhead, unlike shade-tolerant chargers like BigBlue. But these are mere trifles when you consider its raw speed and rugged build. Plus, this solar charger has an ultra-compact and light physique at 16.6 ounces, and an attractive price of $63. Who knows, after some tinkering in the lab over the next year, Ryno may be the panel to beat. The X-Dragon is versatile, allowing you to charge a wide variety of devices quickly, thanks to its high-efficiency conversion rate. Its rate of 23.5% is significantly higher than the 15% standard conversion rate found with other solar chargers. It means it doesn’t require much sunlight to keep your devices juiced when you’re on outdoor adventures. And it can adapt the power to deliver the fastest current under direct sunlight. It achieves this with its built-in smart chip, which has the ability to adjust the current-voltage based on the connected device to maximize charging capabilities. The solar panel is built to withstand your rugged adventures. It features weather-resistant Oxford fabric. It keeps your devices safe with its surge and short circuit protection. Choetech’s 19W solar charger has been around for a decade, and it will be around for at least another. This ultra-compact charger is the smallest on our list, and it will effortlessly slide into your pack. Plus, it’s almost as lightweight as the Ryno Tuff. The small charger is a beast that can juice up devices almost as fast as the Ryno Tuff through its 2.5 Amp dual USB charging ports. The Choetech has a reputation for being a very stable charger, able to reach 9W. Plus, it adapts well to clouds that may come and go. Built with embedded metal rings for enhanced attachment onto backpacks, Choetech is an irresistible pick at the current price of $35 at Walmart. It’s a worthy rival to the Ryno Tuff on any given day. It can quickly charge two devices at once and consistently renews charging after cloud interruptions. It’s a pretty durable piece of equipment. Best of all, it doesn’t sacrifice on size – it is one of the smallest and most lightweight options on the list. They also had to excel in charging on sunny days as a minimum requirement. Chargers also had to be rugged, portable, and available at an affordable price point. They also had to be highly regarded by reputed gear testers and consumers alike. I also considered pricing, offering models that ranged in price from $35 to almost $80. In turn, the solar chargers I chose deliver superior value. For camping and trekking, anything above 28W may be too big to schlep around. Anything less than 15W could get you in trouble – smaller panels have more trouble charging, especially in dodgy weather. Plus, many devices won’t charge at all with a weak power source. If you’ll mostly experience sunny weather on your outings, look for one that is powerful, lightweight, and compact. If you want a solar charger that is reliable in different weather conditions, look for an option with large panels. Also: The best camping gear and tools A better idea is to purchase a separate external battery pack that you can charge during the day and then use to power your other devices at night. Look for a battery that has a solid weight-to-storage ratio. And make sure that it has the ports your devices require before you buy it. Otherwise, you’ll likely have to buy an adapter to use it.
