Review: Anker 733 Power Bank (GaNPrime PowerCore 65W)

It was not too long ago when GaN chargers became the latest and greatest in device powering technology. Due to their efficiency, GaN chargers can transfer more power to your devices with less energy being lost to heat. They considerably outperform previous generation silicon charging solutions which run hotter, charge slower, and are generally larger in size. If you have not already switched to GaN chargers for your various devices, you are doing yourself a disservice. However, what if you had a  GaN charger which also doubled as portable power bank? That is where the Anker 733 Power Bank comes in.

Anker already has quite a selection of GaNPrime chargers themselves, which you can check out by clicking here. Those products reach the kind of 100W charge rate that you would expect from a GaN charger. Even with the Anker 733 Power Bank only reaching a max output of 65W, I was still intrigued by the potential applications with a hybrid product such as this.

Let’s check out the $99.99 Anker 733 Power Bank (GaNPrime PowerCore 65W) to see what it brings to the table.

The Anker 733 Power Bank is a product from Anker’s GaNPrime lineup of charging solutions. As it is from the GaNPrime line, it houses an array of power and safety management technologies. With MultiProtect, the power bank has protection against short-circuits, overload, over-voltage and over-heating. ActiveShield provides temperature monitoring to ensure the safe charging of your devices. Lastly, PowerIQ allows the charger to monitor power needs of connected devices, automatically allocating power distribution to efficiently charge each device.

The Anker 733 Power Bank houses a 10,000mAh battery and is capable of a maximum power output of 65W. It has two USB Type-C ports and one USB Type-A port, making it capable of charging three devices simultaneously. The power bank houses foldaway outlet prongs, allowing it to also double as a GaN wall charger. The unit also has a four-LED indicator button that you can press to check the battery’s charge level.

The potency of the Anker 733 Power Bank’s charge rates depend on the amount of devices connected and what mode the unit is in, Wall Charger or Portable Charger. When plugged into the wall, the Anker 733 Power Bank’s highest rates of power output becomes available while its internal battery simultaneously recharges. The maximum output you can get from the 733 is 65W on a single device when the power bank is plugged in. However, when it is in portable charger mode (or “unplugged”), you still get up to a respectable 30W charge rate on a single device. The Anker 733 Power Bank product page has some handy graphics that illustrate the various charge rate scenarios.

As far as base specs and features goes, the Anker 733 Power Bank impresses from the start. We have reviewed our fair share of power bank products here at RFMag. However, it has been some time since we have encountered a power bank whose output surpasses the 18W mark. Simply being a portable power bank that can deal out an impressive 30W while unplugged is impressive enough. However, with its ability to double as a GaN wall charger that reaches up to 65W output, this product is then further solidified as a great travel companion.

Luckily for us, we got our hands on an Anker 733 Power Bank right before our trip to Seattle to check out Pax West. So, we got the opportunity to immediately toss the Anker 733 Power Bank at some common on-the-go charging scenarios. The 733 got right to work, turning a single hotel room outlet into a high speed charging station for three devices.

Without dissecting the individual charge rates for this HyperX Clutch controller and this Cleer Alpha headset, I could tell that the PowerIQ was hard at work. The bulk of the power was going to my Galaxy S22, whose onscreen display reported that it was recharging at “super fast” speeds. The Samsung Galaxy S22 (not “S22+” or Ultra) can charge at a maximum rate of 25W. This is well under the maximum 30W output that the Anker 733 Power Bank can reach in portable charger mode, let alone wall charger mode. Needless to say, it was easy to leave the 733 to allocate the maximum power outputs for all of my devices whenever I had down time during the show.

In one scenario, I used the Anker 733 Power Bank to charge my Samsung Galaxy S22 when it was at 37%. I had an hour to spare before heading out, so I set a one-hour timer to see how much charge the phone would get. As it turns out, one hour was plenty since the phone reached a 100% charge with four minutes to spare. That is a nice 63% charge in 56 minutes. I would imagine the charge would be considerably more if this was the S22+ or S22 Ultra, which can charge at rates of up to 45W. Speaking strictly about portable charger mode, that 10,000mAh battery is able to give the Galaxy S22 two full charges.

In another scenario, I checked to see for how long the Anker 733 Power Bank could sustain a light laptop such as the Lenovo X280 while in portable charger mode. I let the X280 drop down to an 80% charge before connecting it to the Anker 733 Power Bank via a 100W USB Type-C cable. After about 1 hour and 6 minutes, the laptop got back to a full charge. For about 48 minutes more, the laptop proceeded to work directly off of the power that the Anker 733 Power Bank was providing. After that, the Anker 733 Power Bank’s battery was then depleted.

I only used the X280 to field emails during the time, so the laptop was not doing anything particularly processor-intensive. However, 1 hour and 54 minutes of total additional use time was still pretty impressive.

As for charging the Anker 733 Power Bank itself, it took a little less than two hours and a half to recharge to 100% from complete battery depletion. This is not the first power bank we encountered with foldaway outlet prongs. However, it is a feature that is always very appreciated on any portable power bank.

Final Thoughts

At $99.99, the Anker 733 Power Bank (GaNPrime PowerCore 65W) is a great buy for the techie traveler or anyone looking to expand a power outlet to charge multiple devices when traveling. When used as a wall charger, it powers up to three devices at a maximum of 65W. That is perfect for travelers that find themselves in hotel rooms with limited power outlets. When used as a portable charger, you still have a 10,000mAh battery that recharges devices at a still respectable 30W. That is enough to power your laptop, tablet, phone and more, adding hours to your usage time. The only thing you have to worry about is having your power cable(s) handy.

The Anker 733 Power Bank (GaNPrime PowerCore 65W) is the fastest and most efficient 10,000mAh power bank we have used yet. If you have a need for portable power, respectably fast GaN charging or both, $99.99 is a more than reasonable price for a product that delivers like this one does.
