How Do Portable Solar Chargers Work?

At the remarkably low price points of even the highest-quality chargers on this list, it’s easy to think that there must be some sort of magic at work; that surely no renewable technology can be fitted into such a small device, for so cheap? Well, in fact that’s exactly what’s happening here. Solar panel technology doesn’t have to mean massive 12 foot solar panels arranged in long rows in fields, or affixed to the roofs of houses. Today, solar panels can fit inside your pocket or backpack.

So how exactly do portable solar chargers work? It’s really pretty straightforward. Each unit, or power bank, is essentially a hand-sized battery in which electricity (generated by a solar panel) is stored, and from which your devices take the electricity they need to charge, via USB cables plugged into the base of the solar charger and then into your device(s). On top of the unit, a solar panel is built in.

Solar panels are comprised of many small photovoltaic cells, which themselves are comprised of polycrystalline or monocrystalline (mono being the most efficient) silicon. This silicon reacts chemically and physically when exposed to sunlight (in a process known as the ‘photovoltaic effect’) to produce electricity. In essence, like a plant’s biological cells convert sunlight into carbohydrates, photovoltaic cells convert sunlight into electricity. This electricity is then stored in the battery pack for you to charge your device with whenever you like.

The cells of your charger’s solar panel are covered and protected by a thin film of waterproof, weatherproof, UV-resistant glass or plastic (the casing of the entire device is equally durable), ensuring that they can not only continue generating electricity in adverse weather conditions, but will last for a long time, before needing repair or replacement.

Many of the best portable solar chargers come with several USB ports, so that you can charge several devices at once, and some even come with additional features, such as doubling up as a high-powered LED torch: perfect for the outdoor adventurer and camper.

Pros and Cons of a Portable Solar Charger

We know all this might seem too good to be true, and whilst we think that a portable solar charger really is just that good, it’s worth taking a look at the pros and cons of these products. As with all solar energy products, there are both disadvantages and advantages.


  1. Affordable. Even the most up-market, reliable, and customer-recommended portable solar chargers on the market will likely cost no more than $30 or $40, which for renewable technology is a total steal. Remember as well that you won’t need to spend a single cent on energy bills to charge your devices when using solar power.
  2. Lightweight and durable. Most of you who are looking through this list of portable solar chargers are probably thinking about taking yours out with you on camping trips, hikes, holiday or a road trip, since it’s out there – in the great outdoors – that you’ll need portable electricity the most. What’s so great about these devices is that they will not only not weigh you down, they’ll also last a long time, and won’t be hampered by even extreme weather conditions.
  3. Additional features. With solar technology coming on leaps and bounds, it’s no surprise that many of these portable chargers come with impressive additional features, such as wireless charging capabilities, and in-built torches.
  4. Charge your devices over and over. On a full charge, most of the portable chargers on this list can charge your phone and/or tablet many times over – ideal when so many modern smartphones require a full charge on a daily basis!


  1. Charging times. Whilst on a full charge there’s no denying the usefulness and efficiency of these solar portable chargers, it’s getting to the full charge that can be problematic in the first place. Portable solar chargers require anywhere from 6-15 hours of sunlight exposure to reach a full charge. Whilst 6 hours is more than achievable when camping in a sunny area, 15 hours becomes quite difficult to achieve unless stationary for a few days (and to be honest, even then you’d rather that the device charged faster).
  2. Sunlight dependent. This goes for all solar technology as standard, and should come as no surprise: solar powered technology requires solar power. If you’re in an area that’s overcast, or are receiving little sunlight during the day, your charger will take much longer to charge, and thus will not charge your devices as well as it otherwise could.
  3. Slow charging. Solar-generated electricity, as a rule, still isn’t quite at the level of regular grid electricity. As such, you will notice that your devices generally take longer to charge via a portable solar charger than they would when plugged into a wall socket. Not much longer, but still, noticeably so.

Solar Powered Portable Charger Buyer’s Guide

What are the main features to consider when purchasing a solar powered portable charger?


Obviously a primary issue to consider is power output. Obviously a 10W panel will generate more energy than a 5W panel but continuous changes in solar panel tech mean that this value is not set in stone. A 3W model may effectively charge more than a model with higher wattage. The rule of thumb is usually to consider a model with at least a 7W output for smartphones, ramping it up to 15 watts to charge more than one device at a time or more energy consuming appliances such as laptops or tablets.

A more important parameter to consider would be to check out the amperage capabilities of your prospective charger. Next-gen smartphones and tablets are best compatible with models that can offer at least 2 amperes per hour while charging.

Energy Conversion

Another obviously very important factor is how much solar energy is effectively converted and just as important, the actual charging speed. As we’ve seen most models on our list boast a conversion rate between 20-25%. Consider that at that rate, the full charge of say, an iPhone 7 takes around 3 hours in optimal conditions, meaning direct sunlight over a sustained period.

Weight, Size and Portability

As we’ve seen there are some huge size and weight differences between the different models we’ve listed. Obviously the larger a panel the more devices you’ll be able to recharge at a faster rate, but lugging around a massive solar panel when on a trek, hike, camping trip or bike ride isn’t exactly fun so consider the actual use of the solar charger you intend to buy.

An ultralight model is basically a solar powered phone charger, more useful as a survival gear accessory for short outings or emergencies. A larger panel may be heftier to transport but it will guarantee charging of multiple devices. Camper and boat trips are the perfect setting for the latter for example. Remember that all these models come with accompanying items, such as separate power banks and cables so plan accordingly.


Closely related to power output, the number of connections and USB ports a solar charger can offer is of paramount importance. Whether you need an emergency charge for you phone to take a nice pic during an outing or long-term electrical sustenance for a week long camping trip. Figure out which devices to bring with you and how important it is that they stay adequately charged.


Like with any appliance, especially intended for prolonged outdoor use, durability and resistance to the elements is a huge factor. All models reviewed here have high endurance ratings, some being almost completely water-proof. Check for warranties as well, as a model that damages or malfunctions easily can overshadow all its other features if it can’t be refunded or replaced.


The number of additional accessories a solar portable charger can offer is very important. Relying only the sun for energy may be awesome as it is cost-effective and eco-friendly but you can’t count on solar power at all times. Rechargeable battery packs are always a great back-up feature to have in these cases. Other accessories such as eye-holes for hanging, kickstands, durable cables and power indicators are also useful features to look out for.

Final Verdict

Portable solar chargers are a neat, high-tech, effective and environmentally friendly way to keep your electronics charged outdoors or to have supplementary energy during any sort of emergency. Their usefulness as modern solar powered tech products is evident. Considering all the factors above plus the price tag our choice remains the Blavor Solar Charger. A no-brainer choice due to its compactness, versatility and compatibility which make it one of the best well-rounded portable solar charges on the market in 2021.


How effective are portable solar chargers?

Depending on the model, size of the panel and energy output, portable solar chargers can effectively charge multiple devices. Though obviously less rapid than a conventional charger, most models can fully charge in 3 hours of direct sunlight. Models with supplementary battery packs can offer even more charging capabilities.

How resistant to outside elements is the average solar charger?

All models reviewed in this list have very high resistance ratings making them ideal to use in adverse conditions within reason.

What are some important extra accessories to look out for in a portable solar charger?

Durable cables, number of extra USB ports, attachment flaps and power indicators are some of the most sough-after additional features for a solar charger.

Can solar powered chargers power different accessories?

Usually solar powered chargers do more than your typical phone charger. Meaning they can charge multiple compatible devices (even at the same time depending on the model). This can include: laptops, tablets, cameras, smartwatches, GPS devices and even certain car batteries.
