FAQs

Q1: Will this power my DS220j or DS218+?
Yes—designed to match OEM specs (12 V, 5 A). Reddit users confirm compatibility with DS220j and DS218+ NAS units.

Q2: Are the electrical protections safe?
Yes—built-in safeguards like over-current, over-voltage, short-circuit, and thermal cut-off ensure safe operation.

Q3: How do I confirm the connector fits?
It uses the Synology standard 4-pin barrel connector; verify your NAS model uses this plug before purchase.

Q4: Can I use this worldwide?
Yes—input voltage covers 100–240 V AC, so it works globally with local power standards.

Q5: Do I need original Synology adapters?
Not necessarily. Community feedback suggests that output compliance matters most—not OEM branding.
