## Description

Lucstar USB Timer Charging Controller with Appointment and Working for Protecting Camera Phone Tablet Household Fans Applianc - desertcart.com

Review: Dependable. Helps to keep battery charging to 80% - I've had several devices (phones and tablets) whose batteries could barely hold a charge after two years. Back then I was a "plug it in all night" kind of guy, and my tablet was plugged in probably 20 hours a day. I had heard the theory that this treatment led to battery damage, so decided I'd try keeping the battery charge between 20% - 80%. This meant I'd need a way to stop charging at the 80% mark. I installed the Android app AccuBattery, which you can configure to have an alarm go off at a chosen charge percentage. This works fine if you're sitting at your desk and hear the alarm, but doesn't work in other situations, such as if you need to charge your phone at night! I then tried a USB device that goes between the charger and your phone, and connects to your phone via a Bluetooth app. Software on the phone would send a signal to the device at 80% charge point, telling it to shut down the charging current. This sounded like the perfect solution, but there were hassles with making sure the correct device was connected via Bluetooth (I would have both my phone and charger bedside, for example) and for some reason, over time, this device would no longer provide any more than the tiniest trickle of charge, meaning my phone would never get charged. Or ... the bluetooth app would stop running, meaning I'd wake up to a phone at 100% charge. So finally I tried this timer charger, and finally I have something that works! With a bit of testing I know approximately how fast each of my devices charges (what percentage they charge in an hour), so I can pretty accurately estimate how long I'll need to charge something in order to get to 80%. For example, my phone charges about 66% in an hour, so if it's down to 20% I'll set the time for 50 minutes and after that time it will be close to 80%. Another plus is that this can be used on any kind of device, even Kindle e-readers. I have never used the "time to turn on" functionality, so cannot comment on it. In fact, I would prefer for it not to have that functionality, so that the top and bottom buttons can be hour up/down, minute up/down, but this is a minor quibble.
Review: Good for maximizing power bank - This little gadget is small enough (and reasonably priced) where it has a lot of value added for those trying to maximize the life of a battery bank. I use it when traveling, and will (for example) put it on an hour long charge before this device will automatically cut power thereby saving the life of the battery bank. That charge is enough to get me through another day. Without it, the battery bank will continue discharging (all night for example) and I will only get one or two charges. With this thing, I can go a week! Cons: If you have a smart battery and want to put a delay on it to when to start charging, the smart battery will cut power and the charge will never happen. Additionally, this device has no memory, so every time you connect the timer, you have to re-program it. But, for the price and functionality, I love it. Thanks guys!

## Questions & Answers

**Q: Whats the qualtiy?**
A: To Dave V:
The current model that I received in March 2021 does have a setting
retrieval feature.  The next day you want to use it, just press the "C" button twice and it displays the last countdown time that you used, and it will start charging after a few seconds.  It does have to be plugged into power the whole time for this feature to work.  It doesn't store the last timer value in eeprom.

**Q: Is that possible to turn off and automatically turn on after a certain period of time? Any help or suggestion will be appreciated.**
A: NOPE, that was what I assumed as that would be logical but nope.
However, it is easy to tell the device that you want to charge for the same amount that you did the last time by just pushing the center button twice.  This is what I do and one of the advantages is that I don't charge every day on the phone that I use this device. Hence, just push the button twice and walk away.  (But I agree it is a poor solution to an obvious need)

**Q: Does it allow usb data transfer? also while off (not charging)? i would like to use it while tethering a phone to a pc, with the pc supplying power.**
A: Sorry, it doesn't support the data transfer.

**Q: How long is the cable?**
A: The attached cable that connects it to the charger is approximately 22" long. Then you plug whatever USB cable you want into the charging controller and plug the other end into your phone, tablet, what-have-you.

### ⭐ Very Low charging speed
*by P***P on August 27, 2022*

First: The timer I received is scratched up and definitely used. So Beware, the seller is reselling used as though new. Second: The product claims this USB timer can do up to 3 amps. (That's 3,000 mAH) I have tried plugging this thing into several different chargers and none of them even come close to 3 amps. When plugged into my 2 amp charger, I see a charging current on my phone of around .3 amps (300 mAH) The best I can get is around .5 amps when plugged into my 2.4 amp charger. I've even tried a 3 amp charger and it performs worse for some reason. Third thing: The charging current is wildly inconsistent. It's all over the place. I've attached two screenshots of my android app called AccuBattery which measures amperage, voltage and battery life. You can see in the screenshots one is giving about .1 amps and the other is just about .5 amps. This is while plugged into my 2.4 amp charger. Pretty pathetic performance given that the product promises 3 amps. That being said, my unit currently works. Just nowhere near what is promised.
