BigBlue 3 goes above and beyond the rest. Thanks to its impressive charging capabilities and consistent performance across the board, this panel maintains its place at the top of the pack for another year. While there may be other options that charge faster or look cooler, nothing beats this model when it comes to overall performance. When your electronics need a boost, this panel will provide a constant charge in variable conditions (from full sun to partly cloudy). In terms of features, we like the built-in emitter and zippered accessory pouch. We also appreciate this panel’s simplicity and reasonable price tag. With three USB ports and a classic fold-out design, the BigBlue is a great all-rounder that will efficiently charge most small gadgets.

One downside of this panel is its weight. Weighing in at 23.5 ounces, it’s a little heavy. As a result, it is better suited for front country use, although it will be better wherever you use it. Aside from its weight, this panel earns high marks across the board.

Best overall solar charger

With six large panels of solar cells, BigBlue is efficient, even when in partial shade.

Reasons to Avoid

The pocket is too small to hold extra cords and accessories.

Year after year, the Anker PowerPort 21W continues to be a top scorer. It has all the same features as the 15W but with 6W more power. It has fast charging: 3 hours and 40 minutes to charge the 6,000 mAh external battery in full sunlight, one of the fastest in our review. It was also great at charging multiple devices at once, and handled the charge interruptions you’d expect.

It’s not the lightest model we’ve tested, but it does a great job for its size (over 20 watts). Its tri-folding design is magazine-sized and easy to store. This competitor was hard to beat when it came to charging capabilities, weight and price.

Solar Charger – Another great performer

The Anker PowerPort 21W, an efficient three-panel solar charger, soaks up as much sunlight as possible in the Sierra sun.

Charging the battery through solar energy is difficult.

The Goertek 25,000mAh battery pack is a high capacity battery. It has three USB ports for fast charging of small electronics. We like that it has a large capacity and can fully charge the phone multiple times when the battery is dead. Additionally, the small solar panel works well enough to charge the battery with solar energy, even if it takes a few hours. Apart from all these great features, Goertek comes as one of the most reasonably priced options for a solar charger setup.

Our issues with this battery pack are similar to the issues we’ve had with other battery pack/solar options — patience is required. This product does not work as a stand alone solar charger. If you’re planning to fully charge the 25,000mAh battery from the sun, give yourself a few full days. That said, the panel will continue to charge the battery pack, even when small electronics are plugged in, a feature we appreciate.

Unlike the limited energy stored in a battery pack, a USB solar charger offers a small power plant that can generate electricity for your phone and small electronics to charge them when the sun comes out. Save that energy for later. After spending more than 60 hours testing 12 models, we’re convinced that the BigBlue 28W USB Solar Charger is the best portable solar charger for those who need to charge their gadgets and power in an emergency or off-grid situation. Need to stay connected.

Our choice

• BigBlue 28W USB Solar Charger
• Best portable solar charger

This lightweight solar charger gives you the most usable power for its size. In addition, it has three output ports to charge more devices than the competition at the same time.

The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and has unique features that make it more versatile and durable, including three output ports (vs. on chargers), a weatherproof port protector. , and an extensive yet lightweight array of panels to capture every last ray of sunlight. While other models come close to matching it in terms of power, the Big Blue is also smaller and lighter than other options with similar output, so it fits more easily in a camping bag, hiking daypack, or emergency kit. May be.

• X-Dragon 20W Sunpower Solar Charger
• Similar power, less features

If you can’t get our pick, this model is about the same size and just as powerful but equipped with fewer ports and panels.

If BigBlue isn’t available, we also like the X-Dragon 20W SunPower Solar Charger. In testing, it was second only to our top pick in terms of how much power it produced throughout the day, and it even produced slightly more when the sun was at its peak in the afternoon. While this model will charge your devices as fast as our top picks, the X-Dragon lacks the handy extras—like an extra charging port and port protector—that make the BigBlue stand out.

SunJack 60 Watt Foldable ETFE Monocrystalline Solar Panel Charger is a brand new gadget. The company claims that this is the world’s most powerful compact weatherproof 60W solar charger. This solar panel has a power of up to 60 W thanks to four monocrystalline panels.

You can use the 19 V port to connect the gadget to a power station. In addition, you can charge two devices simultaneously directly from the panel via the 40 W USB-C and 18 W USB-A ports. An IC chip intelligently improves charging speed without overcharging. The ETFE outer layer ensures that the gadget is waterproof and dustproof, reducing the risk of damage from drops or shocks. The coating allows up to 95% UV transmittance to make the panel highly efficient.

The portable solar panel weighs 4.8 lbs (2.18 kg) and can be folded to 11.5 x 14.5 x 1.5-in (~29.2 x 36.8 x 3.8 cm), for easy transportation. A mesh pocket on the device enables you to store small gadgets like a power bank.

You can buy Sunjack 60 Watt Foldable ETFE Monocrystalline Solar Panel Charger for US$169.95. Alternatively, you can buy a solar panel bundled with a 100 W 25600 mAh power bank for US$249.95. The power bank has three fast charging ports, including a 100 W output or 60 W PD input USB-C port.

For carrying and storage, the four panels fold together in an extended ‘w’ configuration, with the end panels having elongated frames for easy transport. These mimic the (famous) Jacquary solar panels, so they’re a bit of a clone, but they go the extra mile in terms of electronics, as we’ll see:

Opening the panels is easy enough, although it’s a bit clumsy to attach the four velcro-attached supporting legs – it gets easier with practice! The panels sit at 45 degrees, which is a fixed angle, although you can always lay the panels flat on the ground or prop them up against something else if you absolutely feel like you need the sun during the charging period. But a better ‘tech’ is needed (don’t forget that the sun moves significantly every day!!).

So, we are in the sun and the power is available. By hand, the various outputs are clearly labeled on the plastic end molding on the back of the right-hand panel – these ports are protected from light rain by a 1″ lip, should the shower crop up – the rest of the panel is completely But are waterproof. If it starts raining, mind you, you still won’t get much solar power, so you run the risk of folding the whole thing over and blowing the wind over the exposed ports. are avoiding

Firefly 120W Solar Panels

So the results. I should preface everything by saying that even though the panel is rated to produce 120W, it’s under full sun, standing for panels all the time – in practice, just panels in one place. Except you are dealing with significant degrees of difference. . In the angle at which the sun’s rays strike. Then there is usually a mismatch between the height of the sun in the sky and the angle at which you set the panels. Finally, add in the alarming, if not perfect cloud cover (especially in the UK) and the most I’m expecting from this tech, even in the middle of summer, is around 80W.

But it’s still enough to pass effectively:

Firefly 120W Solar Panels

• USB-A up to 60W using Quick Charge 3.0 protocol.
• USB-A up to 10W, limited to 5V and up to 2A – for devices that don’t need much power to charge.
• USB Type C up to 60W, this time using the Power Delivery 3.0 protocol.
• DC output at 20V and up to 6A, so 120W (theoretical) max.

DC output at 20V and up to 6A via (solar) standard XT60 port, so 120W (theoretical) max again. The XT60 can easily be combined with a ‘Pro’ solar management system, for example, in a caravan.

Now, of course, if the panel itself is only delivering 40W, on a bright sunny or cloudy day, that puts a limit on what a single port can deliver, plus the power generated by your plug-ins. must be divided between I, reducing the effective power through each. Very noticeable and you have to do a bit of mental math if you want to get ambitious with something like this!

It’s worth noting that, not shown in the pictures, Firefly provides a variety of convenient leads, notably XT60 to MC4 (another solar standard) and coaxial DC to DC with multiple interchangeable ‘tips’. , one of which is the designed Jacqueline Power Station which I will look at next. In short, whatever you want to plug it into, there will be a USB connector or DC jack/lead that will fit.

In a real-world test, I had a smartphone plugged into the Type-C and a small power bank was happily charging via USB-A, then the additional (round) DC output on my Jackery Power Station. All together, all happy, and all for free, from the sun(!).

Now for the price – this is a semi-pro kit and in this case comes in at £190, semi-pro prices on Amazon UK. Which I think is pretty decent – aside from the slightly wonky (orange) solar connector (which I don’t plan on using, so it didn’t bother me), the build and materials are top-notch. Equipped with a proper charge store (Jacquery 500, in my case, which I’m reviewing separately here), the Firefly 120 is truly portable (if not pocketable!) and realistic in terms of power output. It is useful.

The FlexSolar 120W Foldable Solar Panel Kit is a portable, four-panel monocrystalline solar panel set with an integrated junction box as well as a separate solar charge controller for temporary off-grid charging needs such as camping, hunting, etc. , or designed for RVing.

The FlexSolar Kit shipped in its display box which worried me at first because solar panels can be fragile if not handled properly. Fortunately, the kit was well packed in foam and undamaged upon arrival. This box details all the features of the solar panel kit as well as its technical specifications.

Design and features

The design of the FlexSolar 120W Kit is similar to most portable solar panels with a few exceptions. A unique aspect of the FlexSolar is the included carrying case. The case is a simple fabric bag with two zippers that run along the edges of the panels. A heavy duty rubber carrying handle attaches directly to the folded panels.

What makes the case a bonus, besides the fact that it adds an extra layer of protection for the panels, is the Velcro pouch on the front, perfect for keeping FlexSolar accessories handy and secure.

Inside the pouch is a small elastic band that fits perfectly around the solar charge controller, a nice design touch.

The solar charge controller that ships with the FlexSolar Kit is pretty basic but definitely adds to the usefulness of the kit. The controller works by protecting connected devices from overcharging, overvoltage and short circuits, as well as adding the ability to charge different types of batteries, such as lead-acid batteries used in cars or RVs. The controller has three buttons to navigate its menus and an LCD screen. The unit also has two USB ports for directly charging devices such as tablets or phones.

The solar charge controller as well as the FlexSolar ships with four cables with Anderson connectors. Interchangeable Anderson power connectors are commonly used to deliver high power electrical current.

Two of the included cables are Andersen bare wire, the bare wire ends are inserted into the terminals of the solar charge controller and the Andersen ends can be connected to another Andersen connector.

An Anderson two alligator clip cable is used to connect the charge controller to the batteries.

The DC5521 cable from Andersen is designed to use any of the 10 adapter plugs and connect the Andersen cable to a solar panel junction box to any power station.

After being removed from the carrying case in the folded configuration, the FlexSolar panels are secured on one side by heavy fabric.

Front flap secures panels closed with Velcro.

Inside the integrated zippered mesh bag is a junction box attached to the back of the panel.

The junction box has a hardwired 10-foot cable with an Anderson plug at the end that connects to power stations using 10-in-1 adapters. It also has three charging ports. A USB 2.0 port that connects to the end of a coiled cable, a USB 3.0 port, and a USB-C port that allows the FlexSolar to charge some devices at 60 watts. The 60W PD USB-C port enables you to charge from both a power station and a hardwired Anderson cable simultaneously as long as your unit has the option to accept charges from both. With an optional cable, you can also use the junction box to chain two 120W panels in parallel.

Unfolded, the panels clock in at about five and a half hours.

The FlexSolar panels were able to pump about 70 to 74 watts of power to the Yeti, which is far less than the 120 watts it’s capable of under ideal conditions, but still impressive for daytime.

If I wanted, I could also connect a 60W USB-C to USB-C cable from the junction box to the Yeti’s 60W PD port to grab some extra charging power.

I had a problem with the 8mm adapter plug. While I found it useful to include various connector points, the length of the plug made it a bit unstable and it fell off a few times with barely a jolt. Again, not a huge problem but I made sure to secure the input with some tape to prevent it from falling off.

I also tested the FlexSolar and its solar charge controller using my FJ Cruiser’s car battery with some great results.

I put solar panels on top of my FJ for convenience which is usually the type of setup you can use in an emergency if you’re out in the woods and your car battery dies.

Again making sure to connect the controller to the battery before connecting it to the panels, I was able to deliver about 12V power to my car battery. Over time the panels will be able to fully recharge the battery even if I’m using it to power other devices at the same time. In a typical RV setup an inverter runs off the battery powering my equipment and then the controller and panels recharge the battery as it runs down. The controller USB ports can also be used in this configuration.

If I were even more power hungry, I could use the USB ports on the solar panel junction box to power more devices at the same time.

Being able to solar charge my car battery is a game changer for me and earned the FlexSolar a spot in my FJ’s emergency kit.

Overall, I was really impressed with the price, portability, and performance of the FlexSolar 120W Kit. Not only does this increase the utility of my Goal Zero Yeti 1000 it can power all my power banks at the same time for as long as the sun shines.

Which I like.

Easy to set up and break down.

The included charge controller adds extended functionality out of the box.

Multiple ports allow simultaneous charging from panels and charge controller.

Which needs to be improved.

Panels and junction boxes are only IP65 rated, not fully waterproof.

There is no included or integrated stand for the panels.

Final thoughts

The FlexSolar 120W Foldable Solar Panel Kit is an affordable, versatile alternative to most similarly powered solar panels. The panels themselves are sturdy, portable and easy to set up although it would be nice if they were more water resistant. The included charge controller adds a lot of value to the kit by allowing you to set it up in multiple configurations depending on the situation. Additionally, the 10-in-1 connector set, charging cables, and multiple ports will work with almost any power station, electronic device, or power bank. The best feature of FlexSolar is that all this versatility comes at a bargain price of $199. Whether kept in your vehicle as an emergency battery charger or as part of a basic RV setup, the FlexSolar 120W Foldable Solar Panel Kit is a great buy.
