Smartphones have been dominating the market since it was first introduced to the public. Since then, more and more people want to be connected to the internet at all times. However, not everyone can recharge their phones through the conventional wall sockets all the time. This is where a reliable mobile charger comes into play. If you want to harness the power of the sun in this manner, you’ve got to get yourself the best solar phone chargers.
One of the best solar phone chargers that you can purchase on the market today is the Anker Solar Charger 21W. You don?t need to worry about the battery level of your mobile phone because this will give you clean, renewable energy wherever you are on the planet. Imagine a device that can recharge your mobile phones with 2.4A (2.4 amps) output on not just one, but two USB charging ports at the same time! You?ll be surprised what this unit can do on a very sunny day.
Anker Solar Charger 21W: Performance
Making us of its trademarked PowerIQ, Anker PowePort 21W is said to imitate the charging protocol of your phone’s original charger. PowerIQ moderates the power so that your device can accept charge in the fastest speed allowable. Unlike the usual 13.5% to 15.5% efficiency, Anker 21W makes use of SunPower Solar Panels, which has a much higher efficiency of up to 23.5%.
Its charging speed in ideal conditions (ex. sunny day with minimal clouds) is 1.5 to 2 times the charging speed when using a wall charger. Although it takes longer, this is actually very efficient for a portable charger.
As for charge times, when using two devices at the same time, it can supply enough power to support both electronic devices. It can maintain the battery power of the devices, and can even add a little (keep in mind that your devices lose charge every second just by being turned on). Anker PowerPort 21W also has power surge and short circuit protection to keep your device safe.
The Anker Powerport 21W can continue to produce power even when the skies are cloudy, which is a huge plus. Other chargers tend to stop working when it becomes shady. With Anker, having three high efficiency solar panels can account for this good feature. There is also less need to orient the panels properly since there are three of them, making them capture a lot of sunlight at any angle.
What is disadvantageous when using the Anker 21W is that it does not have a built-in battery pack. Which means it cannot store the power it receives, so it will only provide its maximum output during daytime. Other solar phone chargers have a storage capacity, hence you will be able to use them like regular power banks.
Anker Solar Charger 21W is portable enough, weighing only 14.7 ounces (or about half a kilogram).?It can fit in your bag or backpack, so you can easily carry it around with you. Whether you are using it for camping or for everyday use, it is lightweight enough to bring around.
The solar panels, which are faced with industrial-strength PET?plastic, are packed in a weather-resistant polyester canvas. And a 3-ft micro USB cable is already included.
Value, Warranty and Customer Service
The list price of Anker Solar Charger 21W is $99.99. But it is currently on sale at Amazon. For the power it provides, it is really worth the money. Other solar phone chargers out there only offer half or a third of the power Anker 21W provides.
As a bonus, you will get an 18-month warranty. And you would surely appreciate their good customer service.
