ZeroLemon Solar Juice Battery Power Bank Review 3I believe that one of the most valuable accessories any techie can carry around with them is a portable battery. They are invaluable when you need to charge your devices in an emergency or even light your pathway back home (a lot of batteries offer a flashlight). The Solar Juice Battery Power Bank from ZeroLemon is an exceptional piece of technology and I’m excited to be able to tell you about my experience with it.

For the past few weeks, I’ve had the opportunity to test out the 20,000 mAh Solar Juice Power Bank. First of all, I want to make a note about the sheer amount of battery life this power bank contains. As a point of reference, a standard mobile phone – let’s say an iPhone 6 – has a 1,810 mAh battery within the device. You could successfully recharge an iPhone 6 11 times with a fully charged 20,000 mAh battery. And so it is with the Solar Juice Power Bank. I’ve used it to recharge several devices over the course of several days and not had it falter while providing power outwardly.

ZeroLemon Solar Juice Battery Power Bank Review 4This battery pack has two standard USB ports. Each port is a 2.1 A output that allows for simultaneous charging at high speeds. The battery pack can be recharged in one of two ways – either through the Micro USB input port or through the solar panel. The battery itself is a top grade A cell Lithium Polymer battery – the strongest, most durable type in the world. The solar panel is a powerful 1.2 W monocrystalline solar panel.

Now, it’s very important to note that with the capacity of this battery and the work that the solar panel has to do, it can take up to 8 hours of direct sunlight to recharge the battery. It can be used in an emergency situation and according to the manufacturer, “SolarJuice can charge your iPhone about 50% power for emergency after being solar ZeroLemon Solar Juice Battery Power Bank Review 5charged for 8 hours under normal sunlight…” During testing, I had the battery in direct sunlight for about an hour, and didn’t notice any huge change in the battery’s charged status. That being said, the manufacturer has stated that it takes an extended period of time for a difference to be noted.

Another unique feature to this battery is that it’s shockproof and water resistant. The ports are open on the pack though so complete submersion in water is not recommended. This power bank also comes equipped with a small LED flashlight that was not working on my particular unit. I take this to be a defect in the particular battery I have. All other features were working as they should be.

ZeroLemon Solar Juice Battery Power Bank Review 6I have really enjoyed testing out the Solar Juice Power Bank and am looking forward to a lot of use in the days to come. One this I need to note is that it is quite heavy. It weighs in at 490g, which is just a little less than 4 times the weight of an iPhone 6.

This is definitely a wonderful battery pack to own. It’s great for camping trips and weekend excursions. I would recommend it for survival kits of any type. With the right connector, you could provide power to a myriad of life-saving devices.
