True Wireless Power Bank for Ultra Convenience

HK$ 780,519

Smartphone, bulky power bank, and charging cables - carrying all of them with you is usually a big mess. How often have you left your cable behind by accident? Or too tired after work you forgot to charge up your mobile devices? Ennercell can solve all these problems for you, so you can finally be free from all the tangled cables that bind you.  

Farewell Cables
Farewell Cables

Reduce everyday struggles and lead the cable-free charging trend with the Ennercell True Wireless battery pack. With double-sided Qi wireless charging coils, you can charge your devices and recharge Ennercell completely wireless. 

Ennercell was designed to be so compact and slim that it can fit into the tightest of jean pockets, not just your backpacks, so you can keep your devices charged wherever you go.

Qi Wireless Fast Charging

Ennercell is a Qi-certified wireless charging battery pack. That means, it's compatible with all Qi enabled devices, including your AirPods. With a battery capacity of 5000mAh, Ennercell can fast charge your iPhone and Android devices at 7.5W and 10W power, respectively. 

Wireless Pass-Through Charging

Ennercell is equipped with circuitry that supports pass-through charging, allowing you to wirelessly charge the Ennercell and your phone at once. Just sandwich the Ennercell between your smartphone and your charging pad and you can forget about it. The pass-through feature ensures the least amount of strain on the battery cell by charging your smartphone first before charging itself. 

Minimal & Light

Ennercell weighs only 122g. It's so minimal and light, you won't feel it there. Also, since it can charge your mobile devices cable-free, you'll never have a tangled mess in your pockets ever again. 


Super Fast Recharge

Ennercell features one waterproof USB Type-C port for super fast recharge. Equipped with PD3.0 (Power Delivery) standard, it can be recharged up to 70% in under 30 minutes.

Use as Charging Pad

Ennercell also doubles as a wireless charging pad when connected to a power source with a charging cable. Now you have a charging pad at home and a portable battery pack for you to take on the go. 

Charge Two Devices

Ennercell can charge up to two devices at the same time. One wirelessly and the other through its Type-C port. 

Water Resistant

Ennercell's buttonless design and waterproof Type-C port allows it to be dust-proof and waterproof with an IP67 rating under IEC standard 60529. 

Reusable Gel Pad

Ennercell can stick on the back of your device with a reusable gel pad and charge it conveniently without cables, so you can toss them in your bag, or hold them in your hand without worries of disruption.  

While many other Kickstarter campaigns end their job after shipments, we go a step further and offer a 1 year warranty that covers defects in materials, faulty batteries and any malfunctions after you receive your Ennercell. We have a very close working relationship with our supplier network in China and are very confident in our quality control procedures. 

Ennercell also has worldwide product liability insurance that covers personal injuries or property damage caused by the product with a USD 1,000.000 limit. 

Ennercell evolved from a bulky complex design, with too many output/input ports, into its current minimal version.
Ennercell evolved from a bulky complex design, with too many output/input ports, into its current minimal version.

From the beginning, we knew we wanted to make a battery pack that is minimal, light and compact, but powerful enough to be useful on a daily basis. We needed an innovative idea that can truly make people's lives easier.

Once we got the idea for a true wireless battery pack, we jumped on this chance to design something that is perfectly balanced for beauty, utility, and most important of all, convenience.

We knew size would be a very important factor in the design so we made the case prototypes of our first designs using FDM 3D-printing to check how small we can make (1). Then, using the same method, made the first prototypes of the internal frame that holds the internal components together (2). After we were able to finalize the design, we used the SLA 3D-printing to create the actual appearance prototype of the case that would look more like the final product (3). Finally, we made production prototypes of the cases using injection molds to test out the production method (4).

During the prototyping process, we tested for performance as well as safety. We needed to ensure Ennercell can have optimal power output (left). And safety was a big concern for us so we monitored the internal operating temperatures too (right)

Ennercell is buttonless. Therefore, we installed a shake activation mechanism to turn on wireless charging mode. In the video above, Samuel demonstrates how to activate the Ennercell, charge a Samsung Galaxy S8 and AirPod case wirelessly, charge two devices at the same time, and using the wireless pass-through feature to charge the Ennercell and iPhone X together, respectively.

The Ennercell team, led by Samuel (Man Fai Chan), has over 5 years experience in creating battery packs and mobile accessories. We have been developing a local brand called Infinity in Hong Kong since 2013 and have expanded to over 1,000 sales points in Hong Kong, Macau, Taiwan, and Australia. We were able to collect first-hand feedback from customers, which helped us to understand the inconveniences people encountered with their electronic gadgets. We used all the data collected to keep perfecting the design until we ended up with the Ennercell.

We've spent the past year on developing Ennercell and have completed many of the steps, including tooling, needed to go to the manufacturing stage. Now, we are on Kickstarter to get a large enough MOQ to help drive down the cost of production so we can bring you a true wireless battery pack at the most reasonable price possible. You can also help us by giving us feedback on Ennercell so we can perfect it even more before we enter the final manufacturing stage. Thank for taking the time to read through our campaign!

Risks and challenges

Bringing a brand new product to market is always risky. But this isn't our first rodeo. We've been making powerbanks and other mobile accessories for over 5 years now, so we are very familiar with the whole manufacturing process. To limit the risks to Kickstarter backers, we've waited until we finished manufacturing tooling before launching the campaign. The only other risk would be logistics, as shipping out rechargeable batteries has always been a safety concern. That's why we've taken extra precautions for safety certifications and also hiring a safe logistics company to ensure the safe delivery of all your rewards.
