As a cheap no-frills charger, it has worked well for me, although build quality might be questionable.

What's Good?
  • Really, really compact
  • Just fast enough for iPhones
What's Not?
  • It's not a GaN charger, and quality is... questionable?

So you got your new iPhone/Samsung Galaxy flagship. What? There’s no charger? Well, you can use your existing chargers, or if this is your first flagship in ages, then you can check out the KUULAA 20W USB-PD charger (KL-CD59). It’s a really small charger with a really small price,

KUULAA 20W USB-PD Charger — What’s Good?

Really, really compact

KUULAA 20W USB-PD charger Review (4)

The KUULAA 20W USB-PD charger is smaller than the size of the UK 3-pin plug (Type-G) and it weighs just 55g. In fact, most of its dimensions are concessions to the UK plug’s shape, and only its length is owed to its charger. And almost a third of that is probably to fit the USB-A and USB-C output ports. There are more compact chargers out there, but those generally only offer a single output, while this here gives you the option to charge two devices at the same time.

When compared with the included chargers from Xiaomi and ROG, this is very obviously very compact. Now, it is worth mentioning that the ROG Phone 6D‘s charger is a 65W unit, so the extra size is justified, but Xiaomi’s old 18W and 33W chargers have no reason being this big.

Just fast enough for iPhones

KUULAA 20W USB-PD charger Review (5)

Apple’s fast charging is still a far cry from what Android OEMs are pushing out nowadays in their flagships. Technically you can fast charge at up to 27W nowadays, but 20W is plenty fast, and many YouTubers have already found that going above 20W yield little gains. The relatively small capacity of the batteries powering the iPhones also mean that even a slower charging speed is sufficient to fill up the tank at an adequate rate. For my iPhone 15 Pro, I am seeing the battery go from 16% to 67% in 30 minutes. 51% charged in half an hour is just nice, and that’s possible thanks to this charger supporting the all-important USB-PD 3.0 9V 2.22A spec.

This spec is also key for those of you who want to get the maximum 15W MagSafe charging speeds with the official Apple MagSafe Charger. There’s also support for the Qualcomm QuickCharge 3.0 standard up to 18W, but given that most devices support USB-PD, you will generally be enjoying the 20W charging speed more often than not. At least, with the current set of devices that don’t come with a charger, all of them do support USB-PD.

It’s not a GaN charger, and quality is… questionable?

KUULAA 20W GaN Fast Charger

If you look on Shopee and other places, you will often see that it is labelled as a GaN charger, when in fact it does not feature any GaN innards and instead relies on conventional SiC ones. That probably contributed to the low price. If you watch this review (in Vietnamese), it is pretty basic in terms of quality, with minimal protections in place. Having said that, I have used it for several days with my iPhone 15 Pro and I didn’t find it to warm up excessively and it worked perfectly fine. I have found no evidence to suspect it of any issues just yet.

KUULAA 20W USB-PD Charger — should you buy this?

KUULAA 20W USB-PD charger Review (1)

Maybe. I got it for just RM9.90. So the price does fit the uninspiring construction as identified by the Vietnamese reviewer. However, as a cheap no-frills charger that has worked decently for me, I still find myself leaning towards recommending it. Perhaps you would be slightly uncomfortable using it with your flagship? Well, maybe you can add one to cart to use with a future mid-range device, when they inevitable begin losing their chargers as well. On 12.12, you can get the KUULAA 20W USB-PD charger for just RM9.02 on Shopee. For your laptop or more power-hungry devices, check out our review of the Rocoren 140W GaN Fast Charger. This one has been tested to be excellent across the board.
