What are the special features of MicroUPS series ?

What are the special features of hashwhy MicroUPS series ?

hashwhy is a brand of RegalDream Technologies. RegalDream technologies launched its first product of 5V 2A MicroUPS series in June 2020. The product was well received by customers. As the first product, it had its flaws as it wasn’t designed to work well with all devices and under all circumstances, because we didn’t anticipate the users using them for those purposes. When the range of devices that the MicroUPS was used to power increased, it enlightened us with a set of new features that would improve the performance of MicroUPS series a lot.

The hashwhy 12V 2A MicroUPS for routers and modems, and the hashwhy 5V 3A MicroUPS for Google Mesh Routers, Raspberry Pi and other 5V IoT devices and boards, incorporated a lot of those improvements and features which we believed, was necessary for better compatibility and functioning. 

Adaptive Cable Compensation

Problem: The first generation of MicroUPS was run on 5V only and was designed to work well with 5V 2A devices, which were located 1-2m away from the MicroUPS. The DC voltages drop a lot when cheaper cables are used and also when the cable length increased. When the users connected a very long cable from adapter to MicroUPS, this resulted in low voltage to the devices connected to the MicroUPS.

How we solved it: hashwhy MicroUPS is equipped with adaptive cable compensation, which means that the device, even if it receives a slightly low voltage, converts the voltage to a stable level, 5V or 12V, depending on the device. This enabled the device to accommodate longer cable lengths as well us improve its performance when a lower quality cable is used.

hashwhy MicroUPS Adptive Cable Compensation enables it to give out stable voltage even if the adapter, cable length or cable quality causes an issue with the voltage

Zero Lag Switch Over

Problem: The first generation of MicroUPS had a 3-4ms switch over delay and there were visible voltage dips and spikes in the first generation of MicroUPS. This, on most occasions, didn’t create any problems to the devices connected. But, nonetheless, improving performance of your device is always how the company strives for a better product.

How did we improve: The new hashwhy MicroUPS series has almost no visible spikes on switching over from battery to the main supply, or from main supply to the battery. The switch over delay was improved to < 1ms, to be far superior in terms of performance.

A representative image of hashwhy MicroUPS switch over from main supply to battery power when the adapter power is switched off.

Voltage Stabilisation

Problem: The first generation of MicroUPS didn’t have a function of voltage stabilisation. It only functioned as a UPS, as most ones in the market does. If the adapter had some stability issues with the voltages, the first generation MicroUPS didn’t make the voltage stable. This meant that, unstable adapters caused issues with the devices connected.

How did we improve: New generation MicroUPS series was introduced with Voltage Stabilisation techniques. This meant that the MicroUPS actively compensates for any voltage drops from the adapter, thereby ensuring a better voltage output to the connected device. Since the device gets a stable supply voltage, the performance and the life of the device could be projected to be better in the long run.

hashwhy MicroUPS series can make the voltages stable so that your devices get a stable voltage, to perform better and for longer life.

Smart Charging

Smart charging ensures that the charging of the batteries of the MicroUPS is cut off when it is full. MicroUPS series incorporates this feature. The IC inside the MicroUPS can sense the battery voltage. It has a built-in charge profile algorithm and programmed charging rate for the lithium ion battery packs connected to them. This ensures that the product charges only when required. The charging happens in parallel to powering the device. Unlike some Mini DC UPS which needs to charge initially to power on, hashwhy MicroUPS can power your devices from the moment you turn it on. It doesn’t have to be charged separately or even touched, once you install the device. It can charge by itself when the power is back on, and also stop charging when the battery is full. No human intervention or care is required for the device.

hashwhy MicroUPS can charge and cut off charging on its own. It is smart enough.

These features and improvements happened because we worked closely with our customers from 2020. The customers were happy to share their feedbacks and contact us for support, stating their issues, which has helped us improve. We would like to thank our customers, for helping us improve. It didn’t happen because we could design, it happened because they showed us the path. This article is dedicated to their sincere efforts to help us grow.

hashwhy 5V MicroUPS for 5V Wireless CCTV Home Security Cameras

hashwhy 5V MicroUPS for 5V Wireless CCTV Home Security Cameras

The market has now wireless CCTV Home security cameras from Mi, Yi IoT, RealMe, Qubo, Ezwiz etc which run on 5V. The independent cameras can be easily placed anywhere and are connected to the internet. They are a cost effective way for surveillance as they don’t need DVR or other expensive and bulky accessories. They also come with easy plug and play, which also reduces the wiring expenses.

RegalDream Technologies (our parent company) has launched the MicroUPS for 5V devices in June 2020 ( https://www.amazon.in/dp/B07YQ8C5PC ) The product came with 5000mAh battery capacity and a 5V 2A output capability. The above video shows the endurance test for the 5000mAh version of MicroUPS with the Mi 1080p home smart security camera.

hashwhy MicroUPS takes in the same battery backup capacity from its predecessor. hashwhy MicroUPS also has a better switching characteristic and a 3A current capacity compared to the 5V 2A output of the earlier version. hashwhy MicroUPS also has a USB C port to enable users the ease to plug in their devices. The output port is still the USB A port.

Some users had found the backup to be inadequate for their use. Thus we have brought in bigger batteries for the same. hashwhy MicroUPS now comes in 3 battery configurations, 5000mAh, 7500mAh and 10000mAh. The power handling capability remains the same.

The following is the maximum expected backup hours obtained while testing, with minimal movement on the camera. When using the IR night visions and motion sensors, the cameras showed a much less backup time, dropping up to 50% for cameras with very powerful IR lights, such as the Mi 1080p steady state and Ezviz steady 1080p smart security camera. The following is the result obtained on Mi 1080p 360 degree camera.

10000 mAh

It is advisable to opt for 5000mAh version if you need a small backup duration and 10000mAh if you need a very long power backup duration for almost a days outage, especially in remote areas. The power backup duration can drop down for other cameras. For instance, ezviz camera runs for about 5-7 hours only on 5000mAh, with IR sensors on. If your application is indoors or where the light is low, we would recommend that you add more battery power to your buy list as the IR consumes a significant amount of power when in night vision.

The Expected Maximum Backup Hours for Some CCTV Wireless Cameras

The following results are collected from the users who use hashwhy devices. These are real life figures and could vary depending on configurations and power consumption of your device, such as IR and night vision usages. These are for references only, and are in no way guaranteed. A normal CCTV camera consumes very less power during the day, and significantly higher power during the night, when it has to emit IR or do image processing. Given below are the maximum backup duration experienced. These can vary with cameras and their configurations. For example, the Mi 360 degree camera, which normally runs for more than 11 hours during the day on the 5000mAh MicroUPS, lasts only for 70% of that time, when it is in low light vision for a few hours. If the hours are extended and the movements and other power consuming features are more, the back up duration can drop down significantly.

Typical Installation Methods - Indoor & Outdoor

The most common method how our MicroUPS is installed for a CCTV is inside a 6×6 inch junction box, which is easily available. The MicroUPS is housed inside the junction box, and is invisible to a normal person. They believe that the camera goes off with power and they can’t see the UPS. Thus, the UPS system is secured from a common man. Even if the main power is switched off, the camera still remains on from the battery. The camera is usually placed on top of the junction box as well. This ensures that the wires from the UPS to the CCTV Camera is not accessible to be cut off. The wire from the UPS out is taken through a small opening just below the CCTV Camera. This is the most adopted method as this requires the intruder to remove the camera or UPS to escape surveillance and both are placed in a very high inaccessible area. This method is also used as a back-up camera for the normal DVR systems to check if someone is tampering with the DVR to ensure a second layer of safety.

MicroUPS is not water-proof on its own. The CCTV installation service providers install the MicroUPS in the 6×6 inch junction box, and seal the box, which prevents water from getting in. Also, placing the junction box in a water free location, and then extending the wire to the outdoor camera could also be used for installing the MicroUPS outdoors, especially in outdoor remote locations.

12V hashwhy MicroUPS for Routers & Modems | Up to 14 hours backup

12V hashwhy MicroUPS for Routers & Modems

hashwhy has introduced MicroUPS 12V series for routers, modems and other 12V devices, which needs upto 2A of continuous current. The most important query that is asked is about the backup duration to be expected for the devices, especially the routers.

hashwhy MicroUPS 12V comes with 2 models, which differs in their sole purpose and battery capacity. The smaller version comes with 5000mAh and the other version comes with 10000mAh battery capacity, which is ample enough for a long power outage. Both have the same dimensions and power capabilities, though the bigger one has almost 100g of additional weight

hashwhy 12V 2A MicroUPS 5000mAh version is designed for people who experience small outages frequently and once in a while, experience longer outages. The bigger, 10000mAh version is for people who experience longer and more frequent outages. It will mostly last for long hours to let you complete your work or gaming in peace, without interruption.

To find the back up hours, we tested the MicroUPS with a few routers, such as the Jio FTTH router, which is rates 12V 2A, the iBall ADSL 2+ router which consumes 12V 1A, BSNL FTTH Modem from Alphion, GPON from other vendors such as Asianet, ACT, Hathway, DEN, KeralaVision, Airtel and a few other private vendors. The power consumptions varied with devices though they were rated for the same absolute maximum power ratings. For instance, a device rated 12V 1A used more power at times than another device which was rated for the same 12V 1A.

The power consumption also varied with the speed of connectivity and the number of devices connected for the same make router. For instance, Jio FTTH Fiber router which is rated for 12V 2A, consumed about 50% more current when data was transmitted at 100mbps, than when it was idle. Given below is the expected backup hours which was obtained while testing with various devices. The backup hours can vary depending on your device, but this should stand as a benchmark on which version should you go for. For instance hashwhy MicroUPS 12V 2A 10000mAh could be used as UPS for Jio Fiber FTTH modem and when transmitting data at 100mbps, it gave a backup duration of 6 hours.

The above data is compiled from various devices which as rated for the absolute maximum given in the bubble on the left. The backup hours experienced are given as a bar graph correspondingly.

5V hashwhy Micro UPS for RaspberryPi, Embedded Boards and devices

5V UPS for RaspberryPi, Embedded Boards and devices

Consumer embedded boards are widely used by hobbyist as well as for Internet of Things (IoT) related products and projects. Most start-ups rely on the embedded boards to demonstrate proof of working, as well as to run their end products on these boards. Some popular names being RaspberryPi, Nvidia Jetson Nano, Beagle Bone, Arduino boards, OrangePi, BananaPi boards etc.

Some applications require that the embedded boards or products run without power interruptions. hashwhy MicroUPS is designed with this in mind. The hashwhy UPS is designed to provide 5V output of uninterrupted supply. The device can give upto 3A of continuous current, which is ample for most embedded boards.

RaspberryPi 4B comes with USB-C power port and up to 2.5A current requirement at maximum. hashwhy MicroUPS comes with 5000mAh, 7500mAh and 10,0000mAh battery options for sufficient backup.

The most common query being asked, is how much of a back up duration can be expected from the hashwhy 5V UPS, when used with the embedded boards. To answer the same, we tested the hashwhy UPS with RasbperryPi 4B (2GB) version. The 10,000mAh version of hashwhy UPS was used for the test.

To check for the backup hours, a python script was run in the RaspberryPi board, which wrote the minutes passed into a file in the storage card. To simulate the complete processor usage, a processor test was run on browser (Chromium).

The RasbperryPi was run on RaspberryPi OS (Buster) desktop edition, with SSH and VNC enabled. Ethernet was plugged in all throughout the test. The python script, the processor test online was run till the hashwhy UPS shut down the Pi, depleting its complete power capacity.

The Python Script used to check the time is as follows:

from datetime import datetime
from time import sleep
while 1:
with open('scr.txt', 'a') as file:
file.write('Working at: %s\n' %datetime.now())
print('Working at %s' %datetime.now())
with open('timerun.txt', 'a') as file:
file.write('Worked for %s min' %x)
print('Worked for %s min' %x)

The processor usage and the RaspberryPi desktop was viewed using VNC when the test was done. A sample screen is given below.

hashwhy MicroUPS test with RaspberryPi 4

Starting Time: 2021-11-29 20:36:43.100338

Ending Time: 2021-11-30 04:23:10.734506

The RaspberryPi 4B was run for 7 hours, 46 minutes and 27 seconds on the hashwhy 5V UPS 10,000mAh version on the test, without any interruptions.


hashwhy 5V UPS has 3 versions for the 3A current output model, 5000mAh, 7500mAh and 10000mAh. The test was done on the 10,000mAh version. Mathematically converting the data for the rough expected backup time, the following are the expected backup duration for the other models under the same test conditions.

0 h
0 h
0 h

The backup duration would vary depending on the power consumption of the processor, the peripherals connected and the features used. This test is to be treated as a reference for the expected backup duration.

To calculate the expected power backup, we could also divide the expected nominal capacity by the average power consumption of the board or device. The energy contained in the 5V UPS is given below

0 Wh
0 Wh
0 Wh

The average power consumption of the RaspberryPi under test was roughly 4.76W (after factoring in the power loss). We could mathematically derive the backup hours expected by dividing the energy in Wh by the power consumption in Watts (W). It is to be noted that there could be a rough 90-95% efficiency of the device and there could be power losses in the cable as well. A thick and shorter cable would increase the efficiency and thereby increase the backup hours and also the voltage available at the input of the device / board.

We went ahead, and tested the back up duration for RaspberryPi 4B, with the 10000mAh hashwhy MicroUPS, with the processor running at 30-60% of its maximum throughput. The ethernet was plugged in all the time, and VNC server was turned on. The RaspberryPi didn’t have any other headers or devices attached to it. The RaspberryPi ran for 10 hours and 19 minutes without interruption.

Starting Time: 2021-11-30 10:35:36.063460

Ending Time: 2021-11-30 20:55:05.092117


Interpreting the above results mathematically for the other variants available, the following are the expected power backups when using hashwhy 5V 3A MicroUPS.
