Manufacturer description

The GuanTing Universal AC Adapter replaces the wall power supply for digital blood pressure monitors and other 6V devices, so you stop feeding batteries into a machine you use every day. It accepts AC100V-240V at 50/60Hz and outputs a regulated DC6V at 2A, covering any device that draws up to 12W. The standard barrel connector measures 5.5mm x 2.1mm with inner-positive polarity, and GuanTing ships eight interchangeable DC plug tips so one adapter can serve several devices around the house. Compatibility is spelled out rather than implied: the listing names HEM-742C, HHP-AM11, HV-F311…

SpecPicks Verdict

SpecPicks scored GuanTing Universal AC Adapter 6V 2A Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. GuanTing's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will this work with my Omron blood pressure monitor?

GuanTing lists HEM-742C, HEM-1111, HEM-7123, HEM-7130, HEM-7131, HEM-7282t and HEM-8713 as compatible, along with HHP-AM11 and HV-F311. Any device rated for DC6V at 0-2000mA should work if the plug size and polarity match.

What size is the plug?

The main barrel connector is 5.5mm x 2.1mm with inner-positive, outer-negative polarity. Eight additional changeable DC plug tips are included for other socket sizes.

Can I use it outside the US?

The adapter accepts AC100V-240V at 50/60Hz, so it handles both 110V and 220V mains. You would still need the appropriate wall-plug adapter for the outlet type in your country.

How much power can it actually deliver?

Output is DC6V at 2A, or 0-12W total. GuanTing recommends keeping sustained draw under 80% of that rating, roughly 9.6W, to protect longevity.

Is it safe to leave plugged in?

It ships with over-voltage, over-current, short-circuit, overload and surge protection in a fireproof shell, and is CE, FCC and DoE VI certified. Check the product listing for current warranty terms.
