IKEA makes cheap USB power adapters

The leakage on the 30W adapter is still within an expectable range for the test standards, the testing I show is the worst case leakage and doesn't consider the impedance of the human body as part of the circuit. It may be detectable but it can still be considered safe. The 45W adapter is still better from a leakage perspective.

Reaching 90% efficiency at 10% load shows how far we've come with small-scale SMPS since the 2000s.

This is the first reviewer I’ve seen that addresses the tingling feeling from adapters. Amazing work

“This video has lots of call-forwards I’m never going to get to.” Optimism and realism were thrown into a blender and I like the result.

Am i the only one who has a high trust in ikea even when it comes to power adapters? It feels like ikea just don't want to make a quick buck they actually want to have a good quality reputation. (I'm Swedish so it may affect my opinion)

"- That's my charger! - No, it's mine! It has the blue sticker on it!" They probably figure it would be mixed up like in a summer camp. Or at home. 😂

At least you don't run the risk of buying a fake adapter from any IKEA store. Grab one if you happen to be shopping there. 15 bucks is probably less than the tip you are forced to give at a restaurant nowadays.

No idea why I watched this as I’m not in the market for Ikea USB adapters but I’m glad I did. I have a 3 socket one from elsewhere which tingles when I charge my iPad with the higher power socket. It’s gone in the bin. I always thought there was something off about that tingle.

IKEA really has some wonderful electronics considering they arent an electronic company. Their automatic blinds are wonderful! I've set up my apple Home to open the curtains when I say "good morning". I feel like I live in a movie every time I do that.

Pickup some rechargeable AAA and AA batteries while you're there. They are made in Japan and probably the best in the market.

OMG so that tingling feeling IS real! I thought I imagined it.

The 30W isn't that bad imo. It meets all the needs of an average person (unlike enthusiasts) - it's safe, it works, it's cheap. If someone wants a charger as cheap as possible that just works, it's not a bad choice.

Although you did measure 252 μA of "AC leakage current" which is indeed above the maximum touch current permitted by IEC60601-1 for Class II devices (250 μA), unfortunately, this isn't how it's supposed to be measured. The Vitrek V74 gives you the "direct" AC leakage current through the DUT and the return connection which goes through an internal ~10 ohm current shunt (at least that's what's in my V63). The standardized touch current tests such as the 'equipment leakage' test requires a special HBM (Human Body Model) circuit to be placed in series, this more accurately represents a realistic touch current a person would experience which will always be lower than the direct AC leakage figure of 252 μA which you measured. So rest assured this unit is still safe and within spec, it likely just has a slightly large Y class capacitor than the lower wattage unit. Also surprised you only tested the unit up to 500 V, the Vitrek V74 is perfect for the 3 kV ACrms insulation withstanding test as required in IEC60950-1 for Class II for ITE devices like this one, I find if a charger is poorly made it will fail this 3 kV test with arcing and sometimes with catastrophic insulation breakdown.

These 2 models are not yet in Australia but I use their older models because they are packed full of safety features and their certifications are believable. So I feel confident using them for small projects all around the house.

When you go to IKEA, pick up one of those free paper tape measures they have in the furniture dept. Keep it folded in your wallet. Weighs nothing.

Grabbed one from Ikea, works great with Pixel phone and Samsung galaxy, provides fast charging on both phones. Thanks for the review. 👍

Thanks for the vid! They are indeed big in comparison with the latest GaN chargers. Looking forward to the teardown!

If they work, they are safe to use and they are cheap they are good enough for me! Thanks for these videos.

Appreciate you looking into these!

Nice measurements and great tools! Good to know I bought the best “travel” charger.
