What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

When your adapter is closer to you, your data cable can reach further. This will ensure that your devices can stay within a comfortable operation zone.

What is a good charging experience? You can move the phone and operate it freely while charging.

Traditional charger have to be plugged into power socket, and power socket carrys AC electricity, which is dangerous to humen. It results that people have to reach out for a charger, but a charger never reach out for people.

The DC power which VoltBot use, is completely safe, which means abolutely NO shock harzard. Our creator will perform eating it in the video at the bottom of this page. No longer need to keep distance from chargers.

Overnight charging on bed? It might be a good news for those who likes to play phone before falling asleep.  

1. LCD 

VoltBot provides a visual charging experience:

  • Display dynamic charging voltage & current. 
  • Display real-time charging speed(power circle). 
  • Display quick charging state. 
  • Display history data, curve.

It is exciting to watch electricity streaming into your devices. Look into the details of charging.

2. APP 

VoltBot has an APP. VoltBot will broadcast a WiFi hotspot named 'VoltBot', the phone can join the hotspot and talk to VoltBot with APP.

With APP, curves of charging current can be observed, with which the actual battery capacity can be calculated. 

VoltBot consists of 4 charging engines, providing 4 independent charging channels. Each channel can be matched to the best quick charge protocol. With quick charge, VoltBot can accelerate charging speed up to 70~75%.

VoltBot supports quick charging protocols, including QC3.0/QC2.0, FCP, AFC, SFCP, Apple 2.4A, BC1.2, PumpExpress and samsung 2A.

Estimate speed ups: (examples, not all listed)

  • iPhone6+/6s+/7/8/X can speed up 70% than small white charger. 
  • iPhone6s can speed up 30% than original charger. 
  • Android devices have too many types, please refer to manufacture's manuals.
  • Full support of Android devices. 
  • Full support of Apple devices.
  • Full support of other phones, such as BlackBerry, Moto, HTC, Nokia and Windows Phone.
  • Full support of other USB devices, such as PAD, PDA, mp3, earphone, bracelet, and etc.

How many adapters have you collected? 10? 20? Hmm...  

You'll no longer need to count, because VoltBot can replace them all. VoltBot can give you any voltage through 2.5V~12V, and this ability even ensures VoltBot a good tool to conduct physics experiment.

VoltBot can be phone charger or pad charger.

 VoltBot can also be adapter of wireless router.

VoltBot can connect to cigar-lighter plug-in, directly utilizing power generated by car.

The benefits of having charger near bed is obvious. Because messages and calls arrive now and then, if we do overnight charging near bed, it would be easier for us to reach out for phone.

There are some advantageous factors of VoltBot to be placed near bed. 

VoltBot equipped environmental light sensor to auto adjust its backlight power. So its screen will go dim when you fall asleep. And a side key is implemented, you can also switch the screen on/off mannually by pressing it (same as phone). Auto-Backlight is default on. However, some people may have special tastes, wishing screen to be shining in the night. Just use the APP or web-browser, configuration interface is there.

Left: Auto-Backlight Off                                   Right: Auto-Backlight On

We also implement Auto-Cut-Off function to further protect your battery. You can find the demo video in the bottom of this page.

VoltBot brings you into a world of physics hobby and electronics DIY. Under DC Supply Mode, DC voltage within range from 2.50V to 12.50V can be synthesized immediately. It can be used to power your gadgets and home-made circuits. Real-time current displayed on VoltBot's LCD and power curves monitored by its APP helps you to analyze your gadgets' working condition. Compared to a conventional DC power supply, VoltBot is much smaller.

 1. Smart Power Supply

VoltBot is a smart DC Power Supply. It has 4 independent output channels. Each channel has a high-speed digital power engine inside. Those engines provide low ripples and fast transitions. Their efficiency is optimized to achieve low self-heat and high stability. With converters converting USB plug-in into dual-screw jacks or banana jacks, it is possible to use VoltBot the same way like a traditional DC power supply.

Real-time voltage and current is printed on LCD. Power curves can be read with APP.

2. Easy to setup

Easily switching between Charger Mode or DC Supply Mode. Beneath DC Supply Mode, VoltBot is always ready to output the voltage exactly as you tapped-in.

Web Page 

VoltBot embeds a page server inside. This feature eables you access VoltBot by most devices such as Pad, laptop, or Phone. No APP installation is compelled. With this feature, we guarantee your VoltBot will be accessable 100 years later, and can be accessed globaly.

Touch-Key

There are 4 touch key designed on upper edge of VoltBot, you can use those key to setup VoltBot quickly, toggle between common voltages(3.3V 4.0V 5.0V 9.0V). A demo video of touch-key is uploaded at the bottom of this page.

App 

The App (VoltRobot) also has configuration interface.

The volume of VoltBot is only 3% of the traditional Power Supply. It’s portable and saves a lot of desktop space. VoltBot provides a perfect solution for common user: electronic fans, DIY makers, and students.

To create an experiment comprised of serveral electronic gadgets, one big problem is that different gadgets require different power inputs.VoltBot will fit the gadgets' needs.

VoltBot has Wi-Fi connectivity, which meas it can be accessed not only in one room, but also globally. With Internet status and control of every power channel can be accessed remotely.

VoltBot also has UART interface, you can directly embed it into in-field system as a module, controlling and monitoring the power with your Arduino, Raspberry Pi, Embedded System and industrial controller.
