    Reasons your solar power bank is not charging

    There are many reasons why your solar power bank might not be charging. Here are the five most common ones:

    The battery has reached the end of its life

    Unfortunately, no battery lasts forever. It’s inevitable that it’ll reach the end of its lifespan after performing a certain number of cycles. If you’ve had your solar power bank for some time, your battery might have lost its ability to hold a charge.

    You’re not using it properly

    Although technically, you use your solar power bank while it’s charging (in an emergency, for instance), this practice isn’t recommended. Doing so frequently may result in your solar power bank not charging or charging erratically. When you do this, the power banks’ battery is in line (or in series) with the gadget. The result is a higher power draw which leads to excessive heating that can damage your battery.

    Your solar panel isn’t getting enough sunlight

    A common misconception is that the solar panel in your solar power bank can generate electricity on a hot day, even when placed in the shade. That is not true — solar panels require direct sunlight to work effectively. Additionally, solar power banks require a minimum amount of luminous flux per area unit (also called lux). If they don’t receive the minimum amount of lux, they won’t start charging via solar. The following image showing the charging instructions of a standard solar power bank serves as an example. Notice that it requires a minimum of 25,000 LUX sunlight to charge via solar.

    Wrong or broken charger/power cable

    If you’re trying to charge your solar power bank using a USB charger and it isn’t charging, the issue might not be your power bank. It could instead be the charger or the cable. Make sure you’re using the correct charger, one that delivers the proper voltage and current (as required by your solar power bank). If it still doesn’t work, the charger (or just its power cable) could be broken.

    Excessive battery drainage

    We recommend that you recharge your solar power bank before you drain it completely. If you drain your power bank completely, it’ll require more energy to get going again instead of charging it from a 50% state of charge. As a result, if you deplete your solar power bank entirely, it might take even longer to charge with solar, or in a worst-case scenario, it might not charge at all.

    How do I know if my solar power bank is charging?

    Charge your power bank properly. Doing this ensures that it provides you with power when you need it.

    Led indicators

    Most Solar Power Banks on the market have four tiny LED indicators that flash progressively when charging. Although they may vary in size and color, you can quickly identify them on your Solar Power Bank. Advanced models display different LED colors to indicate the charging source. After reading the User Manual from a few different Solar Power Bank models, we’ve noticed that for most models:

    • Blue LED: Indicates USB port charging
    • Green LED: Indicates solar charging

    Furthermore, the LEDs indicate the state of charge when the solar power bank isn’t charging (and the LEDs aren’t flashing). In this case, the lights represent:

    • 1 LED on = 25% state of charge
    • 2 LEDs on = 50% state of charge
    • 3 LEDs on = 75% state of charge
    • 4 LEDs on = 95%-100% state of charge

    Logically, when fully charged, your solar power bank should have its 4 LED Indicators active. As it discharges, the indicators gradually turn off.

    Because of the variety of models, you might find yourself with a device that indicates charging differently than the way we described.

    For this reason, we strongly advise that you read your device’s user manual. There, you’ll find all the information you need, specific to your solar power bank model.

    Ways to fix a solar power bank that won’t charge

    If your solar power bank isn’t charging, don’t panic! Here are a few things you can try to get it up and running again:

    Add extra solar panels

    If you’re trying to charge your power bank with solar energy after draining it completely, it may not charge at all.

    Why? The surface area of your power bank’s solar panel might be too small to generate enough electricity to get the redox reactions in the battery going.

    In this case, adding extra solar panels might fix the problem. You can attach/connect small solar panels to your solar power bank (if it supports this addition) – you can easily find them online.

    This will increase the solar input of your power bank until it recharges to at least 50%. After this point, the electricity generated by your main solar panel (without the extra ones) will probably be enough to continue charging your power bank.

    Try charging it with electricity from a wall outlet

    As mentioned above, your power bank might be too drained to start recharging only with the small energy input the solar panel provides. If this happens, don’t give up on your solar power bank just yet. Pumping up some juice from a wall outlet might bring it back to life.

    Place it in direct sunlight for an extended period

    Solar Power Banks can take over 50 hours to recharge using solar energy. Considering how many hours of sunlight are in a day, it could take an entire week to recharge your solar power bank.

    For this reason, it may seem like it isn’t charging, when in reality, it’s just taking a long time.

    To maximize sunlight absorption and overall efficiency, one way of speeding up this process is to place your solar power bank in direct sunlight for an extended period.

    Check for any loose connections

    A more elaborate way to fix your solar power bank requires some skills. If you have previous experience repairing electronics, you could try opening your solar power bank to check for any fraying or loose connections.

    For instance, your solar power bank might not be charging because the wire that connects the solar panel to the circuit board is loose.

    In this case, using a soldering iron to solder the loose wire will fix the broken.

    Check if the battery is dead

    This one also requires exposing the inner pieces of your solar power bank.

    Depending on the battery’s chemistry (and its nominal voltage), you can tell if it’s dead by using a voltmeter to check its voltage.

    If you conclude that it’s dead, the only way to fix your solar power bank would be to replace the battery. This procedure might not be cost-effective, so do your research before buying a replacement battery.

    Here’s a little tip: You can also use the voltmeter to measure the output voltage of the solar panel. Maybe the battery is fine, but the solar panel isn’t generating any electricity.

    If you’ve exhausted all your options, and cannot find a way to fix your solar power bank, it’s time to invest in a new one.

    How Does Solar Power Bank Work?

    In Brief, Solar energy is the electrical power that is derived from sunlight. The conversion of this power can either be directly using photovoltaics or indirectly through a concentrated solar panel system. These solar panel systems make use of lenses or mirrors to FOCUS sunlight on a small beam.

    When we talk of solar power chargers, the name says it all; it is a battery storage unit of power that derives its energy directly from sunlight. They can be very useful during trips or when there are power shortages. They are becoming popular as each day goes by as more Smart devices are being invented and they need more power to work and last for a day. Generally, the power banks act as a backup.

    Most people who own a solar charger power bank, do not know how they work and it is very rare to find a seller explaining to a customer how these gadgets work. Solar power banks have special lenses that concentrate the sunlight on a small beam in order to charge the batteries inside. The battery has a circuit that controls the power flow obtained from the sunlight. These batteries store the electrical energy converted from the sun, which is later used to charge various electrical devices like mobile phones.

    What Are The Advantages Of Solar Power Banks?

    You can use them anywhere! As you know, there are no wires needed with a solar-powered device. You only need to find enough sunlight and place your charger in direct sunlight to charge it up. No matter where you are in the world, you can find some sunshine if you wish to charge your phone or laptop.

    They’re environmentally friendly! Another advantage of using solar-powered devices is that they’re environmentally friendly; there’s no pollution from them whatsoever since they don’t release any carbon dioxide into the air like other batteries do when they’re depleted and thrown away after use (because there’s no way for them to be recycled).

    They’re durable! Solar-powered devices are also very durable compared with other types of chargers because there are no moving parts inside them (unlike with regular batteries). Therefore, there’s no chance of them breaking down quickly.

    What Are The Disadvantages Of Solar Power Banks?

    Solar panels take a long time to charge up. If you’re planning on using your solar power bank for emergency purposes, you might be disappointed by how much time it takes for the device to fully charge. In fact, most solar panels can only generate about 2-3 watts per hour — meaning that it could take up to 10 hours for the device to reach full capacity when exposed to direct sunlight.

    Another disadvantage of solar power banks is that they are generally quite bulky and heavy compared to regular power banks which don’t rely on solar energy. This means that they’re not always ideal for carrying around in your all day long!

    Benefits of Using a Solar-Powered Battery Charger

    Solar battery packs are the most energy-efficient and economical devices that someone can have. They no doubt make life so much easier. There are numerous benefits that they bring to our lives. They include;

    They can charge without any electrical input. This means that they have no associated costs that they bring along.

    They can be used anywhere, You just need to have access to sunlight.

    They are very versatile and can charge any basic gadget. You will never have to worry about any electrical shortages as the sunlight will always be present even for a little while.

    What are the Types of Solar Energy Chargers?

    There are very many manufacturers, and all of them have different concepts and designs. As a result, there are various different models and types in the market. These are the most popular types:

    Small, portable models which are designed to charge a wide range of small devices, including cell phones, mobile phones, iPods,s or any other small portable gadget.

    The fold-out models are designed for automobiles. They sit on the dashboard and are plugged into the cigar lighter socket to charge the vehicle battery when it is not in use.

    Public chargers are installed in public places for people to use for free.

    Next, we will discuss and feature the 10 best solar power chargers of the first type which is Small portable models.


    Solar power is the best alternative power source that can help us take care of the environment. It can help reduce the reliance on fossil fuels.

    When you think about it, it is also very cheap considering the lifetime of benefits that one is going to get. There are even smaller systems that can supplement household power needs. This can be an important step in establishing a sustainable power grid.

    WBPINE 24000mAh Solar Power Bank Review

    The WBPINE 24000mAh Solar Power Bank Review is an all-around superstar when it comes to battery life, solar charging ability, and portability all rolled into one relatively small package.

    WBPINE 24000mAh Solar Power Bank

    We purchased the WBPINE 24000mAh Solar Power Bank so our expert reviewer could thoroughly test and assess it. Keep reading for our full product review.

    If you’re in the market for a portable solar power bank, then you want to find a device that maximizes power and efficiency. The two main factors are the battery size and the number and wattage of the solar panels. There are single-panel solar power banks with large batteries or even power banks with up to five solar panels that FOCUS on solar energy conversion.

    The WBPINE 24000mAh offers an attractive blend of battery and solar power. You get a massive battery, three capable solar panels, and a portable and durable design that makes this device great for extended outdoor use.

    Design: Attractive but with a few quirks

    Weighing in at one pound, this solar power bank is definitely a little hefty. But that’s not a surprise given the massive 24000mAh lithium polymer battery. It resembles a smartphone in shape and dimensions, but because of the large battery and the two solar panels that fold out, the size is more comparable to three smartphones stacked on top of each other.

    Stowing the panels for travel is easy. Simply fold them in and secure them with the convenient snap closure, sort of like a wallet. The manufacturer also supplies a carabiner that you can hook to the leather loop attached to the clasping mechanism. (With the carabiner attached, clasping the device together is a little more difficult.) Also, because of the weight of the product, we did find that the snap can easily come undone or get twisted up with motion.

    The WBPINE 24000mAh offers an attractive blend of battery and solar power.

    We did not carry it around with the solar panels unfolded, but if you have a larger pack, we think this is definitely a comfortable option. And because of the heavy-duty plastic and faux-leather materials, it definitely stands up to some jostling. We knocked it around a bit on rocks and grass and found it to be quite durable.

    There’s a great built-in LED flashlight on the back of the device with three light modes: steady, SOS, and strobe. Operating this light is not as straightforward as pressing the button, which is another design hiccup we noticed—instead, you have to press and hold the power button for a second or two and then press it again to cycle through the other modes.

    At the same end as the flashlight, you’ll find two USB 2.0 ports and one micro-USB port. They’re all protected by a cover that locks into place to keep out water and debris.

    The power indicator panel is located around the corner from the USB ports. The green light means it’s picking up a charge, and the other four indicators (each representing 25% battery capacity) flash blue when charging or in need of a charge, or solid blue when powered. Because this panel is small and on the side of the device, it’s not as easy to read the charge level—but that’s probably not a huge concern when in motion.

    The WBPINE 24000mAh features an Intelligent Protection System to keep the device safe from short-circuiting, but there’s no waterproof rating. We found light rain didn’t impact it too much, but the manufacturer also recommends avoiding submerging the device in water. Based on our experience with the power bank in a few seconds of heavy rain, we recommend keeping it dry as much as you can, and would caution against exposure to water other than light rain.

    Setup Process: A little lengthy but worth the wait

    Out of the box, this solar power bank was about half charged. Though it’s possible to reach a full battery with a day or two of powerful sun, the manufacturer recommends plugging it in the first time for maximum charge capacity and for the best charging performance.

    We followed the directions and plugged the device in to charge via the included micro-USB cord. The initial charge took seven hours.

    After some use, we did test the WBPINE’s solar charging capacity. Stating with 0% charge, four hours in direct sun on a sunny day brought the device up to 25% (it did get very hot to the touch, however.)

    Four hours in partial sun resulted in the same gain of about 25% charge. The manufacturer claims that it can fully charge over a 20- to 26-hour period. We experienced too much rainy weather to really be able to test that, but judging from just the more short-term tests we conducted, the solar charging function is one of the best aspects of this device.

    Charging Speed: Fast and steady

    After initially charging it on a power source, we maxed out the WBPINE solar power bank by testing out a few different devices including an iPhone 6S Plus, iPhone X, Kindle Fire, and Google Nexus 5X.

    First, we gauged whether or not the charging speed was accurate. We took a reading of the device against each of these smartphones and tablets using a USB multimeter, which captured the voltage and amperage measurements. The manufacturer claims a charging speed of 5.V/2.1A, and that seemed to be pretty accurate.

    The iPhone 6S Plus read at 5.04V/.89A and so did the Google Nexus 5X. The iPhone X came to 5.04V/.97A and the Kindle Fire’s charging speed read 5.02V/.96A.

    Short bursts of sun can still do a lot to boost the battery.

    In terms of actual charging time by device, the iPhone 6S Plus and iPhone X took about two hours, the Google Nexus 5X took just shy of three hours, and the Kindle Fire charged in four hours.

    We also found the charging speed to be quite fast. In 30 minutes, the Kindle Fire went from 0% to 7% and the Google Nexus 5X reached 29%.

    As for the average charging time of the WBPINE, we recharged it a total of three times and found the average complete charging time to be nine hours. That’s relatively slow, but the payoff is worth it since the battery will last for an impressive amount of time.

    Battery Life: Head of the class

    WBPINE claims that you could rely on this solar power bank for two weeks to charge cell phones. With adequate daily sun, this could probably very well be the case. Even our mix of sunny and cloudy weather over a week in the city showed that short bursts of sun can still do a lot to boost the battery.

    On a single charge, we found that we could fully charge two phones, an Android tablet, and simultaneously bring up a phone from 0%-90% while also streaming media for three hours.

    We also tested the battery capacity by attaching a drained Kindle Fire to the WBPINE and streaming YouTube videos until the charger ran out of juice. We found that we could easily rely on this power bank for nearly 11 hours of continuous use.

    Price: A little pricey, but it depends on what you’re looking for

    The WBPINE 24000mAh Solar Power Bank retails for 44.99, which isn’t bad considering the enormous battery. But there are options that offer a slightly larger battery for less, although with fewer solar panels. Others come with additional features like Qi wireless charging and a slightly larger battery for just a few dollars more. But if you want the battery and solar conversion power the WBPINE 24000mAh offers, we’d say this power bank is worth the price.

    Competition: Weighing solar and battery power

    The Hiluckey 25000mAh Solar Charger is nearly a carbon copy of the WBPINE 24000mAH, except for a couple of big differences. The Hiluckey offers 1000mAh more in battery power and an extra solar panel for a few dollars more than the WBPINE. While this option does offer more solar power wattage, it also adds on more weight, which can be a drawback if you’re trying to keep your pack as light as possible.

    Then there’s the Elzle 20000mAh Wireless Solar Charger, which offers a Qi Wireless charging bank in addition to three solar panels and a 20000mAh battery. For about the same price as the WBPINE, the Elzle offers two USB inputs plus wireless charging capabilities, which would allow you to charge a Qi-enabled smartphone and two other devices. It does have a smaller battery capacity, though, so if you don’t need the wireless charging ability, the WBPINE is the better option.

    Provides stellar battery power and effective supplementary solar charging—a great charger for a trip off the grid.

    Its durability leaves something to be desired (don’t leave it outside in any heavy rain), but for the average adventurer, the WBPINE 24000mAh will likely fit the bill as a charging source for smartphones and tablets on your next adventure off the beaten path.
