Electrical energy storage is an exciting and ever-changing aspect of our digital lives these days. Burgeoning futuristic technologies like high-density supercapacitors and graphene nanomaterials show how eager we are to store and transmit power more efficiently. The lithium ion battery has come to be our most viable solution for energy storage in most small electronic devices. Over the past forty years many improvements have been made to increase energy density and efficiency of Li-ion batteries. The significance of this technology led its orignal developers to be awarded the 2019 Nobel Prize in Chemistry. Lithium polymer batteries are one variation of this technology which yield a more reliable and lighter-weight battery. This is currently the most desirable battery type for portable and accessible energy storage, or power banks.

It can be frustrating when your cell phone, tablet, wireless earbuds, drone, smart watch, portable speaker or other wireless device runs out of battery power at the wrong time. That's where lithium polymer batteries come in. A small lightweight bank will complete the modern digital life, whatever your lifestyle. You may need one on the go throughout your working day, to keep in your briefcase on the subway or in your purse while going between meetings. Perhaps your embarking on an outdoor adventure where you'll need something more durable with more charge capacity. An eventful day at the zoo with your family could easily require some portable energy. Or when you're just at home or the office, you may need a small, simple, and efficient wireless charging station that doesn't require the hassle of cables. Whatever your needs, there is an occasion-based power bank for you.

ON THE GO

All of our banks use a smart control system, a tiny microcontroller that constantly monitors the system and regulates electricity intelligently to maximize charging efficiency and minimize loss. For everday "on the go" use, we offer four small and economical types for various applications. All come with a 10000 mAh charge capacity (enough to charge an iPhone 4s about four times), fit easily in your pocket, come in black or white, and boast the same quality and efficiency of all of our products. The A1 model is the simplest with two USB output ports and a MicroUSB input port to charge the bank. It has a 4-LED indicator to show how much charge is in the bank. The A2 model also has two USB outputs but can be charged with MicroUSB or the newer USB-C connector for faster charging. It also comes with a digital display, more precisely showing the charge level to a percentage point. The A3 model has the same four ports as the A2, but the faster USB-C port can be used both ways: to charge a device from the bank or to charge the bank itself. So it can charge up to three devices at once. The B1 model is a sleaker design, smaller (about the area of a credit card) but slightly thicker than other models, and boasts the same charging ports as the A3.

ADVENTURE CHARGING

For more rugged use and a higher charge capacity, we offer three adventure models. At 30000 mAh storage capacity (enough to charge an iPhone 4s about twelve times), these banks will give you an abundance of excited electrons for days. The C1 comes in white, red or black with a textured surface and displays the charge level precisely as a percentage on a digital display. It has two USB outputs, a USB-C input and output, a MicroUSB input and an Apple Lightning input. The C2 is the Cadillac of our adventure chargers. At first glance you'll notice the lustrous, colorful display which can show the charge perentage as well as the output voltage and amperage, a nice perk for us nerds out there. It has four USB outputs, a MicroUSB input, a USB-C input or output, and an iPhone port. One of the USB outputs is a Quick Charge (QC) enabled, for ultra-fast charging of compatible devices. The USB-C port uses the Power Delivery (PD) protocol so the bank itself can charge at 18W, allowing the bank to charge from empty to full in ten hours. The C3 model has a very minimalistic design with nothing on the face of the bank. The charge level is discretely indicated by four LEDs on the side and the same ports as the C1 model. This adventure line is great for spending days in remote areas without electricity, such as a multi-day backpacking trek or a few days at a remote cabin in the woods.

HOME CHARGING

A modern home isn't complete without a wireless charging station. The inconvenience of plugging and unplugging, as well as the need to periodically replace damaged cables is eliminated with wireless QI technology. We have three stylish models to choose from with slight variations between them, all with overcurrent, overheat, and over-voltage protection. The H1 comes in black or white, round or square. It uses the USB-C input for charging and provides up to 15W of power output, enough for any portable device to charge as quickly as possible. The H2 is round with a matte finish, provides 10W of power, and uses MicroUSB to charge. It also has an intelligent system which can detect a 9V device and charge it automatically. The H3 is a model manufactured by Samsung, a trusted brand by many of us. It charges by MicroUSB and offers 5W of output power.

EVENT CHARGING

For a simple power bank to take to an event such as a festival or outdoor camping, our event charging models are ideal. The W1 with a 10000 mAh capacity, charges from 0% to 50% in thirty minutes and only takes three hours to fully charge. It has one USB-C input and one USB-C output. The D1 has a 20000 mAh capacity (enough to charge an iPhone 4s about eight times), can be charged by the USB-C port or the MicroUSB port, and it has two USB outputs. The D2 has a sleak minimal design, holds 20000 mAh of charge and comes with a four-LED indicator of the charge level. It has two QC-enabled USB outputs for fast charging of devices and a two-way USB-C port that can charge devices or charge the bank. The D2 can also be charged via a MicroUSB port.
