Anker 24w Portable Solar Charger

Best Solar Phone Charger – Solar iPhone Charger Review

Price: $80Best features: Flexibility

Most solar chargers use the same kind of solar panels like the ones that go on your roof, made of the element silicon. The Anker Portable Solar Charger does something different and has solar cells made of copper indium gallium selenide, or CIGS. These are a type of thin-film solar panel that is physically flexible, meaning you can bend the panel itself without breaking it. This added flexibility makes the Anker charger a good option for more rugged trips if youre worried about damage to your gear. Importantly, the charger needs to be in direct sunlight and connected to your phone to charge, as there is no connected battery pack. However, you can always buy a separate one and charge it up for power when the sun is not out. Ankers product still has enough power to be effective, and it can support charging three different devices at once.

Charging Your Mobile Phone

with solar power works in one of two ways:

  • A solar panel charges a rechargeable battery, that in turn charges your mobile. This means you can charge your phone even when there is no sunlight – at night for example – so long as youve charged your battery during the day. The battery can be an internal Lithium-ion or removable AA NiCads or NiMHs .

    • With this type of arrangement, the capacity of the battery will determine the number of times you can recharge your phone before you need to use the solar panel again.

    • Internal Li-ion batteries are an excellent lightweight, high capacity option, but it may be useful to have removable AA/AAA batteries if you can use these for other devices.

    • The power of the solar panel will determine how quickly the internal battery is charged. The speed at which your phone is charged from the batteries will not change.

    • Beware, many chargers do not have a blocking diode to stop power draining back from the phone into the battery. You should always monitor charging and disconnect your phone from an empty battery.

    As USB ports have become increasingly prevalent as a means of charging in recent years, more solar panels have come onto the market with a USB connection. Examples include the MMP USB charger , MMP and Sunlinq panels, and the Powerfilm USB charger.

    Best Solar Phone Charger For Hiking

    Portability is the most important factor when shopping for a solar phone charger for hiking. Look for a charger thats lightweight and which you can hang from the back of your backpack to charge your phone on the go.

    It should be foldable so you can easily pack it in your bag when you dont need it.

    High output is not super important since youll be in the sun for hours. A 5W-21W solar charger is enough to charge one or two phones at the same time.

    Multiple Device Charging Speed

    The 21W from Anker is a powerhouse when it comes to charging multiple devices. Like the BigBlue, the Anker was able to deliver some charge to two devices simultaneously, which is certainly impressive for a panel of its relatively small size. The Anker 21 charged our phone 4% when plugged in next to a battery pack, which is similar to panels of the same size, and earns the Anker a high score in this metric.

    If You Want To Charge Your Phone With Solar Power Get Two Products Instead

    There all-in-one products that pair a battery with larger solar arrays that work quite well, but after taking a close look at the available options I think the best solution for most people is to buy two separate products: a good portable solar panel, and a battery that fits your needs.

    With this approach, you can select a solar panel large enough to fit your particular power requirements, and also choose a battery that has the features you need. For example, you might want a battery with Qi wireless charging, which is a feature not found in cheaper products.

    How Do You Know What Solar Battery Size You Have To Choose

    The answer depends on how much power you want to generate. A standard solar charge for boat battery may have a terminal voltage rating of up to 20V. However, they function at an ideal power required by a 12V battery to attain full charge.

    Traditionally, solar chargers are measured in terms of Amps since it is easier to determine how much amp-hours they use in a day.

    If youre confused about what solar battery size you should use on your boat, the rule of thumb is to divide its total capacity by two. The resultant number is the size of the battery it can maintain. For instance, a 2000 mA solar boat charger can maintain a battery of up to 100Ah.

    Best Budget Solar Charger

    Blavors Solar Power Bank does a little bit of everything, and does so at a very attractive price.

    You Can Find A Multitude Of Products For Charging Your Phone Or Other Small Device With Solar Power But Most Have Underwhelming Performance Here’s A Better Solution

    If you want to use solar energy to keep your smartphone or portable electronics charged, you can find hundreds of choices on Amazon. We took a close look at a few of them in an earlier article.

    While some of them do a pretty good job, itâs also true that most of them donât work nearly as well as most people expect. If a product is advertised as a solar phone charger, you generally expect it to actually charge your phone on a sunny day.

    Unfortunately, many of the products on the market fail to do just that.

    There are a few reasons. One is that these devices have too few solar cells, often advertising 5 watts or less of solar generation. 5 watts is equivalent to the small USB chargers that are included with most smartphones. If they actually achieved that power output, these products would do a decent job.

    But solar cells only generate their rated power output under bright, clear skies and cold temperatures, which small solar phone cases will rarely do.

    The worst type of solar phone case looks like the one above: a cheap case with just one small layer of solar cells on the rear. Youâre meant to place your phone face-down in sunlight to charge your phone. In addition to having too few cells this also means that, unless youâre outdoors at noon, the solar cells wonât be perpendicular to the sun, causing the power output to suffer.

    How Much Power Do You Need To Charge A Phone

    Before I tested the solar panel, I wanted to verify my test setup by using the multimeter to measure the power output of a basic USB charger. If your phone came with a charger, it was probably a cheap 5 watt model. This is also the kind you find at the checkout aisle of any store. You probably have several of these around the house.

    Plugging the multimeter into an Apple 5 watt charger, I measured the output as 4.8 watts , which is just a little shy of its rating.

    This is really the minimum power output you need to charge a smartphone. With 5 watts, it will take several hours to charge a phone that is completely dead.

    For this reason, Iâm testing a 10 watt solar panel. I want extra solar cells to make sure I can reach at least 5 watts in good sunlight.

    Best For Fast Charging

    Features: 25,000mAh | Charge up to six times faster | Waterproof and shock-/dust-resistant

    The Hiluckey 25,000mAh Powerbank uses four high-efficiency panels and up to 1A input current in a vibrant orange. This means that you can charge your devices up to six times faster than competitor models.

The auto-detection feature is an added convenience, automatically searching out your devices for a more stable and reliable connection. It is compatible with both Apple and Android devices, as well as iPads and other tablets. In fact, you get multiple uses out of this powerbank because its Li-polymer battery can charge tablets up to 4 times and phones up to 10 times.

    An added bonus is the unit’s durability. It is not only waterproof but also resistant to both shock and dust. A multi-function LED flashlight helps light the way if your phone is dead, offering an SOS mode to signal help in the event of an emergency. The built-in hook offers easy storage when you are done using your powerbank.


    Limitations Of All Solar Phone Chargers

    Solar recharging power bank! Lights, USB phone charger!

    The biggest limitation of ALL solar phone chargers is also what makes them so great: the sun.

    Without direct sunshine falling on your solar charger, its not going to charge your phone or will do so painfully slowly.

    This is especially a bad problem for combo solar chargers that have integrated battery packs. They often include such low capacity solar panels that it would take days of perfect sunshine to recharge the battery.

    Normally, you wont get perfect sunshine, even in the summer. Clouds can form, or you may be traveling through a thickly wooded area.

    Thats why I recommend you get the highest wattage solar phone charger you can afford. It will charge your phone faster even with limited sun exposure time.

    If you are planning to spend more than a couple of days in the wild, dont get an integrated solar charger+power bank unit. According to most campers, this type of integrated charger will frustrate you because of the low wattage solar panels, sometimes as low as 1 watt. Instead, get a high capacity solar-only charger and buy a couple of battery packs to charge with it.

    Another issue with many solar phone chargers is their lack of versatility. They can only produce enough power for small devices.

    Unlike larger portable solar chargers, you cannot use them to power your laptop, lamp or medical device.

    The payoff is that you’ll get a charger small enough to put in your pocket.

    Buying Guide To Choose The Best Phone Solar Charger

    The value or worth of a product is always subjective. But to make things easier, here is my short list of factors you should consider while buying something.

    • Choose the best product you can find: Quality is the most important consideration when buying phone solar charger. If you want a product to be durable and offer good value, look for one of excellent quality.
    • Invest in the best durable product: How long does your phone solar charger normally last before breaking down? The investment is worth it if you have a product that exceeds your lifespan expectations.
    • Always buy from a reputable brand: Established brands are more reliable than new ones since they have a long history of success. Some vendors are also renowned for providing excellent customer service.
    • Take note of consumer reviews on various websites: Review sites such as Amazon can provide you with information about other persons shopping experiences.

    Consider these elements before purchasing phone solar charger:

    How Long Does A Solar Phone Charger Take To Charge A Phone

    If the solar phone charger has a built-in power bank, your phone will charge in 2-3 hours depending on how much power the USB port delivers and the battery capacity of your phone.

    If your solar phone charger doesnt have a battery, meaning you are charging directly from the solar panels, charging time depends on how much sunshine there is and the wattage of the solar panels.

    A 21W solar phone charger can fully charge a phone in as little as 2-3 hours in direct sunlight. In poor sunlight with a low-wattage solar phone charger, it can take a whole day or even a couple of days to charge your phone.
