Stopped working after a few days

Purchased this and did not work with a Laser 20000mAh Portable Charger but worked with a 10000mAh charger.

It worked for a few days then would only stay on for maybe fifteen minutes. Contacted seller two days ago and have not heard anything back.

Response from Colin Hickey | Sept. 24, 2024

Those two days were a weekend. Customer contacted me on a Saturday and I replied on Monday, I try to keep my weekends to spend with family which I don't think is unreasonable. I am a one person store and not amazon. Customer has not replied to my message but has had a full refund.

I always try to work with customers if any issues do occur.

Great product! Works exactly as described.

This is the product that I was searching for. I was trying to use a power bank to provide power to a low-power Bluetooth device via USB, but the power bank turns off automatically after about two minutes. So I ordered two of this keep-alive unit. The seller shipped the products literally on the next day, and the package crossed the Atlantic Ocean in seven days, and appeared at my doorstep in the following week.
I tested the two units on the same power bank with auto power-off feature, and was happy to report that they both work exactly as described. They successfully disabled the auto-off feature of the power bank, thus keeping it on in a sustained manner. The connected Bluetooth unit has been receiving sustained power for more than an hour thus far, without causing any apparent power drain on the power bank.
The attached case was definitely built to last, with a strong semi-transparent white plastic, although it's a little thick in height, making the device almost like a cube. I don't think I can post a picture here, but the actual dimensions of the product are: L = 45mm (including 13mm as the length of the exposed male USB connector), W = 25mm, H = 18mm). But I guess it's good design by leaving sufficient space inside it to facilitate heat dissipation.
Overall very good product! I will definitely recommend it.

It works

I bought a couple and they are all good and they work as expected. I have yet to test and comment on the longevity of the units that I have with me, but so far in my experience, I must say the creator did a phenomenal job on these small useful devices.

Jay | Oct. 8, 2023

man o man - This experience sucked

Item did not come with instruction - QR CODE Goes no where due to a down server. I assemble it based on images, plug it in, does not work. Show it to the maker, says its done right, then says my battery must be the issue. Bought what i thought was an assembled kit as well, the full kit, but it was parts.
Offers to refund me the goods less shipping, after a month, I have still yet to get it. Sure he means well, but ill never buy here again.

Response from Colin Hickey | Oct. 10, 2023

Jay bought a kit by mistake when he was after assembled units. I have tried to work with them to come to a solution but i was not able to give them a refund label to ship from the US to the UK for free as he'd ordered the wrong thing by mistake. I issued a refund minus the postage so he got two products for free which was done 13 days ago promptly after they accepted the offer. I am sorry that it did not meet their expectations but i am a small single person company and not Amazon.

Raven | Sept. 19, 2023

Super Simple

These are really amazing, compact keep-alives that can be used with lots of different projects, such as stringing together multiple USB power banks. Simple and reliable with a 3D printed case too. Shipping was really quick as well! It would be neat if they had a way to vary how much power they "blip", without needing to go to the do-it-yourself version (for someone like me who's not great with soldering). Thanks for the amazing work you do!

Matt | Aug. 24, 2023

Excellent!

Great product, solves my problem. Very fast shipping, I received it in the US within about a week of placing the order. Thanks!

Essential device

Hello. Apologies for my poor English.
I respect Mr Colin's maintenance and communication with users on Discord.
I purchased Colin's RS485-WiFi module and used it on my EPEver Tracer AN3210 series. This was what I was looking for in terms of UI, functionality and size. It is an essential device for me and It has been in use for a full year and is now in its second year of use and am very happy with it. Due to the incredible increase in electricity prices due to the war in Ukraine, I bought an additional charger with a maximum of 60A as I plan to add more PV and generate more than 30A. We bought a PWM type controller and an MPPT type controller, both from EPEver, which have RS485 terminals and can connect an MT50 monitor.
I am going to try now that both can be monitored with the RS485-WiFi module.
Question for Colin. My only problem is that the start time of the day has shifted and it is now 7:00 am and the month starts on the 4th and I want to fix this, I unplugged the RS485-WiFi from the charger connector and reconnected it, but this did not fix it, so I unplugged the battery connection and the solar connection that feeds the charger and disconnected the power completely. Is the solution to disconnect the battery connection and the solar panel connection that feeds the charger and disconnect the power supply completely and reconnect it again? I would do this at the beginning of the month.

Stopped working after a week of use.

Worked well for a week then stopped working as designed. Will not keep power bank activated anymore longer than the default.

Response from Colin Hickey | April 12, 2023

Always happy to help if your having issues, just drop me a message.

Thanks
Colin

Rick | March 28, 2023

Quality Product

Functions exactly as described. Keeps my battery pack from shutting don due to low current draw. Excellent seller to work with.

Saiful Azree | March 26, 2023

Solve my issues..

Been looking for a device that can make the power bank continuously supply to my sensors. Bought a few of them. Feel a bit warm when connected but they work. Thanks.

Pierpaolo | Feb. 23, 2023

Works perfectly with all my power banks

Simple and great design, easy to assemble. The optional case closes perfectly if you have the foresight to mount the capacitors so that they do not protrude too much from the printed circuit.

David | Feb. 14, 2023

Works very well on 4210AN controllers.

Plug and play in my 4210AN controllers.
I tried it on several of my controllers and it worked well on all of them.

Samppa | Jan. 29, 2023

Perfect. This is exactly what I needed.

Really quick delivery and product is as described. Early days so far but I've connected this to a battery with led strip lights with a motion sensor and module is ticking over to keep the battery alive. Not sure about the battery drainage but all looking good so far.

Łukasz | Dec. 6, 2022

Everything is OK.

The product complies with the description, but in my case it did not work with Powerbank Baseus BS-30KP365.

Roy | Nov. 11, 2022

Does exactly what it said it would do.

I needed something to stop my power bank switching off (VariCore V20i charger/power bank) when I connected my modded FX chronograph. It was switching off after 10 seconds due to low current draw. This little module did the job perfectly. I ordered the extra 3d printed case and it keeps everything compact and protected. I can now use my chronagraph for as long as I want. The 2 3000mHa 20700's should last for months before needing charging.
Communication has been fantastic with email notifications all the way from order to delivery . The module was packaged very well in a small box and arrived in perfect condition.

Stanislav | July 18, 2022

Great

Thank you, works fine.
Looking forward to complete my project for bicycle lightning via powerbank :)

Niklas | June 21, 2022

3

3 because it doesn't work with all my power banks, and I understand they all have different configurations.

Good overall

Csaba | May 3, 2022

Great product not for AN series.

I purchased this for an epever tracer 3210AN. For the RJ45 the right pinout is T568B. However the COM port of the Tracer AN can only supply 100mA. This is not enough for the ESP8266 WIFI to work so it will freezee. If you supply enough current with other power source then it works great. Need to redesign this in order to work with Tracer AN series out of box.

Response from Colin Hickey | May 3, 2022

Hi,
Is it a brand new AN series as there are many people using it with AN models currently. I’m wondering if they have made a change to all models going forward.

Thanks
Colin

Don | Nov. 30, 2021

Perfect!

Just what I needed for Big Clive's Super Computer, and various other projects.
Bypasses the Power Bank Auto-Off feature with absolute negligible power drain.
Excellent quality product. Well made (complete with 3D Printed Case).
Competitively priced, Well packaged, Fast International shipping (AU).
A pleasure to deal with. Many Thanks! :)

Teemu | Nov. 8, 2021

Great!

This is exactly what I wanted! I have few low current devices and now I can use them with a power bank with this adapter. Fast delivery (including customs clearance with new EU restrictions). Thank you! :)

Stefan | Oct. 13, 2021

funktioniert nicht wirklich

Schlechte Beschreibung, Takt viel zu schnell, da kann man gleich einen einfachen Lastwiderstand verwenden.....

Julien | Oct. 12, 2021

Excellent little kit

Very straightforward and works a treat!
Colin's been very helpful through a small logistical SNAFU :-)

James | Sept. 22, 2021

Exactly What I Needed!

Wow, this thing works great.... It keeps my little power bank powering my STM32 development board from shutting down in my prototype. Perfect! Thank you so much for offering this little device for sale! Great price too. --Jim, Boston, USA

Sam | June 28, 2021

Great little device

No problems at all with this kit: basic construction, simple easy to follow instructions. Everything required was supplied, works well.

Andrew | May 4, 2021

Tidy, Neat, and integrates well

I purchased this to work with a 50A Tracer. It's replicated and more the internal metering available on the MT50 and I'm using it to publish directly to MQTT where home-assistant takes over any plotting and status changes.

Delivery to AU was good (covid delays considering), the 3D printed case needed a very minor tweak to get the USB outlet aligned for programming the latest lolin D1 minis, but in normal production use (one RJ45 cable from the charge controller), this is a non-issue.
The discord community is active, and there's a steady stream of minor tweaks and improvements happening on GitHub.

"Yes, I would buy again" :-)

Raven | Feb. 1, 2021

It works!

This gadget's perfect to help keep USB power banks from falling asleep, and the little orange cases they come in are really solid. I used a USB power meter to see how much power it uses on its own (without anything attached), and it reported 49 mA per hour. Shipping was fast too. Thank you!

Mark | Dec. 13, 2020

Great! Does exactly what it should.

Keeps my power bank alive when powering most low-powered devices I tried. Easy to assemble (provided you can solder and can read resistor colour bands) and the optional case fits perfectly. I might recommend adding a marking on the pcb to differentiate the male and female usb connectors, as one could solder them in the wrong positions. I figured it out by looking at the photo. Maybe I missed something? But this only took two minutes to figure out.

Frank | Dec. 13, 2020

The Keep Alive Timer kept my powerbank alive as described.

The shipping form UK to NL took a bit, but the package arrived in good shape. The PCB was of giid quality and the soldering was easy. Once assembled the product kept my powerbank on.

John | July 10, 2020

Very cool!

Delighted to get a properly finished product well packed and delivered quickly! Nicely soldered in a very clean 3D printed case that closes with a very comforting but easy 'snap'. I wonder if Colin would offer a case with embedded initials for an extra sum?

Volker | June 13, 2019

alles o.k.

Bin sehr zu frieden , ein schönes bauteil. es funktioniert sehr gut . die beiliegende Anleitung zur Inbetriebnahme war sehr hilfreich

Brett | Feb. 5, 2019

Perfect!

I ordered this to test with a BN series common negative charge controller - it works perfectly!
It arrived pre-programmed with ESP-Link firmware, setup was as simple as connecting to the ESP wifi, browsing to the ESP's web interface on http://192.168.4.1 and setting the name and password for the network I wanted to connect it to.
I'm using socat on linux to connect the virtual COM port and Colin's scripts to dump data into InfluxDB for graphing in Grafana.

This is a well designed solution and I look forward to purchasing more when they're available.

Michael | Oct. 30, 2018

Easy to assemble, works great
