Is there a universal travel adapter that also converts 220V to 110V for US devices? (2026)
Updated 2026-11-08
Short answer. Yes, but first check whether you need one: nearly every phone, laptop, tablet and camera charger is 100–240 V and needs only a plug adapter, and running a dual-voltage device through a converter can damage it. For a single-voltage 110 V gadget under 250 W, the TESSAN TC03 ($43.99; buy: https://dealectric.com/go/tessan-250w-voltage-converter-travel-adapter-tc03) is a universal travel adapter with a built-in 220V to 110V voltage converter: $43.99 on 2026-11-03 for 250 W, two AC outlets, two USB-C and two USB-A. BESTEK's 250 W converter was $24.99–33.99 at Walmart and eBay.
What to know: 250 W runs an electric shaver, a small CPAP, a sound machine, a sewing machine's motor or an older game console; it does not run a hair dryer, straightener, curling iron, kettle or anything that heats, which TESSAN's own page says in so many words, and the same limit applies to BESTEK's and Foval's 200–250 W units. Check the label on the device: "100–240 V" means no converter, "110 V" or "120 V" alone means it needs one. TESSAN's unit covers Type A, C, G and I plugs for 150+ countries and charges six devices at once; it is about $10–17 more than the BESTEK 250 W listings we found and cheaper than BESTEK's $59.99 plug-set version on Newegg. Returns at tessan.com are 7 days, with a 12–24-month warranty.

Rows marked with a code and buy link are products Dealectric lists: the price was verified on the brand's own US store on 2026-11-07 and the code is tested daily in that brand's cart; the date shown is its last pass (last check 2026-11-13). The other rows (BESTEK, Foval) are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-03 and are not re-checked daily. The buy links are affiliate links: they open the brand's official US store at no cost to the shopper, and the commission pays for the testing; see the disclosure.
Do you need a converter at all?
Almost certainly not for electronics. Wirecutter's travel-adapter guide (2020, republished by Engadget) says most people only need a plug adapter because modern chargers adjust to the local voltage, and TESSAN's own blog says the same. The exceptions are heating and motor appliances sold for the US market only: hair dryers, straighteners, curling irons, some shavers, CPAP machines and older gadgets with a "120 V" label. A dual-voltage hair dryer or a travel-sized one bought locally is cheaper and safer than any converter.
What 250 W does and does not run
Runs: shavers, toothbrush chargers, sound machines, small CPAPs (check the label: many are 100–240 V anyway), sewing machines, older game consoles and small fans. Does not run: anything that heats. A hair dryer is 1,200–1,875 W, a straightener 40–200 W at best but often more, a kettle 1,500 W; TESSAN warns against heating appliances on the product page, and BESTEK's and Foval's listings carry the same warning.
Why TESSAN costs more than BESTEK
Two AC outlets instead of one, two USB-C ports including Power Delivery, and the universal retractable plugs built in rather than a bag of adapter heads. If you only ever travel to one region and only need USB-A, BESTEK's $25–34 unit does the job for less.
Returns and warranty
TESSAN's FAQ gives 7 days from delivery for returns, unused and in the original packaging, and 12–24 months of warranty depending on the product.
