Costco Members: 2-Pack Anker Fast Charging 67W and 30W GaN Wall Chargers

Is this overkill for an iPhone?

Is this overkill for an iPhone?

Anybody know if these can reliably be used in 220v Europe travel with adapter? Brought three chargers along a few years ago and only a 1amp Motorola survived. One burned up within 2 days, the other a week. All were clearly stamped for up to 220/240v. Had to buy one locally to ensure we could keep our devices charged the rest of the trip.

Gann??? I saw but didn't buy since it didn't say Gann on box

I would rather have just the 67W for $18-20. Is the 30W useful for charging a laptop? I guess you look at it like a free charger at home for your phone. I like the 67W multi port with small form factor because you can take it anywhere and charge multiple devices. its great for a college student who is on campus and can bring just one small charger to charge all his devices between classes or at the library.

If you're interested in this for your Samsung S24 Ultra or any newer devices and hoping to get that sweet sweet Samsung Super Fast Charging 2.0, I'll save you some time. TLDR: this won't do it, but it kinda will. SFC2.0 requires 9V/5A, this charger is 9V/3A. You'll also need to be a 5A (100w+ cable, sold separately). They're cheap, around $10-$20 for 2 nylon ones from anker with great warranty. It's not common knowledge, so many will buy a regular cable and not achieve the best speeds.

The 67w charger appears to be the Anker Prime 67W GaN charger (rb.gy/zv0hu0). There's multiple charging standards: Power delivery, quick charge, PPS... so it doesn't help with Anker introducing their own standards with PIQ (explained here: rb.gy/somo9r). Most companies 'trick' you by selling a 30w charger with multiple ports while not achieving the full 30w while using a single port (max wattage for each port: 20w + 15w) or a '65w charger' that can't fully provide 65w. It's an issue since many laptops can run on 45-65w chargers, people buy the 65w charger as a replacement for their large OEM brick only to find out it's not strong enough.

Good news is that Anker's been around for a long time and reputable. Don't expect max speeds while using multiple ports simultaneously, but with single port charging each USB-C port provides the full 67w whereas usb is 22.5w. It's typical for charging bricks that DO PROVIDE the full charging speed to only offer it on ONE PORT. You'd have to read the manual and know which one it is. Not the case here.

It's also a GaN charger which means less heat, lasts longer, smaller size among other benefits. It also has all the newest features included like Active Shield 2.0 which monitors the temperature and optimizes charging rate by adjusting it. Heat=Bad for your battery. If you normally buy no name brand chargers or china ones or noticed your charger/phone getting very hot, it's most likely the charger. It could also be an issue with your phone's software which is unlikely, much more likely to be a cheap/bad cable and/or charging brick. FYI anker has a great warranty, lifetime replacements on some cables, years for other products. They replaced a few of my cables that went bad after 5 years.

Back to charging... Anker Power IQ 4.0 (PIQ4) means USB Power Delivery 3.1 + Programmable Power Supply (PPS). Basically the charger will negotiate with your device on how fast to charge it. In most cases you get 45w charging around 10-25%, 35w til 50-80% or so and it drastically drops afterwards to trickle charging. A kind reddit soul expunges more on PIQ4 here: rb.gy/xug714
If you want the summary of PIQ version support, it's:
Power IQ 1.0: Supports 5V/2.4A max
Power IQ 2.0: Compatible with QC 3.0 + Power IQ 1.0
Power IQ 3.0: Compatible with QC 3.0 + PD 3.0 + Power IQ 1.0
Power IQ 4.0: Compatible with QC 3.0 + PD 3.0 + Power IQ 1.0 + Dynamic Power Distribution(automatically detects and adjusts the voltage output of connected devices and shortens the overall charging time).

Finally, here's a statement from anker on why you aren't getting Samsung Super-Fast Charging 2.0 (SFC2.0) (rb.gy/hdwkdj).

"In summary, the following prerequisites are required to achieve Super fast charging 2.0" mode:
-A USB-C to USB-C cable rated at 5A (100W)
-A Samsung phone supports 45W fast charging
-A 45W or powerful charger that follows the latest 9V/5A PPS charging protocol, such as our 736 Nano II Charger and GaNPrime Chargers."

This 67w charger is 9V/3A, not 9V/5A. Which means your phone won't show SFC2.0, at least consistently. I have a variety of chargers and many from anker. Some show SFC2.0 initially for a few minutes but reverts to fast charging. The difference on the S24Ultra with SFC2.0 vs Fast charging is only about 10min for 0-100%. I personally charge up to 80% since the s24u provides roughly 12hrs screen-on time, 2-3 days screen-off time, or 19-23 hrs mixed usage. SFC2.0 will charge the phone from 0-80 in 20-30min whereas fast charging will take 40-60minutes. Either way, it's a great charger, at a great price, from a reputable company (Anker+Costco). It's a shame that costco doesn't provide much information on the box or website but hopefully this'll save some people the frustration and headache. Anker's warranty is usually very generous at a few years and this may be covered under costco's electronics free additional warranty. Make sure to keep a photocopy of your receipt and anker will replace it a few years down the road if any issues occur.

If you really want SFC2.0, there aren't many options. But I can attest to the Anker 313 45w charging block, currently $20 on amazon, with Anker 333 6ft 2-pk charging cables currently $12 on amazon. Most will be happy with this deal from costco for the warranty and 2 charger package. But for a similar price you can use the charging features on a flagship phone. Anker just had a valentine's day sale with many items 50% off, set an alert on slickdeals for the 313 & 333 and I'm sure you could get both for cheaper. Don't fall for the trap of getting a 'more powerful' 65w charging brick or ones with multiple ports, they seem like better value but aren't capable of doing SFC2.0.
