Can anyone suggest a USB UPS that is compatible with the DS218+ for use in the USA and under $200?
Cheapest UPS (Uninterruptible Power Supply) For Synology and Qnap will be from CyberPower value series. They come with USB port which need to be connected to your NAS. Then within a NAS you can set the rules what happens wen electricity is gone. There is always Cheap, cheaper and cheapest UPS- what matters is the time it will last without power.

just to let you know the information. I just went and buy budget UPS PowerWalker VI 850 SHL and it works normally with my DS-418play. The NAS recognize it. Tested and it shows it can run around 57 min in battery mode. I have two disks curretnly in my NAS and Ubee router is also connected to same UPS.
Many thanks for the info, I have purchase a PowerWalker Basic VI 600 STL UPS from Amazon for £50 (cheapest I could find)- UK USA , I’m happy for you to edit and provide my feedback if you wish to use it on your website:Initial tests show that the DS720+ recognises the UPS, device info provides manufacturer as ‘1’, model ‘600’, out-of-the-box battery @ 100% charge was 2400 seconds of runtime but after a quick couple of tests, UPS battery recharge looks like it will provide at least 3600 seconds of runtime (with only basic services and a single idle docker instance running). Shutdown and unit power-on after AC power restore work flawlessly. Highly recommended for a basic and cheap line-interactive UPS.Cheers,
To enable local UPS support on Synology:
- Connect the UPS device to a USB port of the Synology NAS.
- On the UPS tab, check the Enable UPS support checkbox.
- Select when the Synology NAS should enter Safe Mode after power failure occurs.
- Choose whether or not to send a shutdown signal to the UPS device when the system enters Safe Mode. Most UPS devices can automatically turn on when power is restored.
- Click Apply.
Standalone Mode – USB
To operate under USB standalone mode, follow the steps below:
| 1. | Plug in the USB cable on the UPS to the NAS. |
| 2. | Select the option “Enable UPS Support”. |
| 3. | Choose between whether the NAS will shut down or enter auto-protection mode after the AC power fails. Specify the time in minutes that the NAS should wait before executing the option you have selected. After the NAS enters auto-protection mode, the NAS resumes the previous operation status when the power restores. |
| 4. | Click “Apply All” to confirm. |
