I Take This Portable Charger Everywhere I Travel and It’s 33% Off Right Now

The handy Anker 622 MagGo snaps right onto the back of my iPhone, and I take it basically everywhere I go. Prices on all colors are discounted to as low as $32 on Amazon.

I take my phone with me wherever I go, and I’m not afraid to admit that I’ve come to rely on it for just about every aspect of my life — from getting news, weather and navigation help to staying in close contact with friends, family and co-workers. That means, like many people, I live in constant fear that my iPhone’s battery will die on me right when I need it most. That is, I did until I found the Anker 622 MagGo, which CNET ranked as the best magnetic power bank with an integrated stand, and which I now take with me everywhere I go.

In my opinion, this charger is a worthwhile buy even at its full retail price of $48. But right now you can get every color for a solid discount of about 33% off. The cheapest option is dark gray, which is on sale for $32, while all other colors — lavender, white, mint green and pale blue — are all available for $34.

Here’s why I’ve stuck with this little charger for so long

Have you seen people walk around with a loop of cable hanging from their pocket to their phone? I’ve been there and hooked that loop on too many chairs and table corners. Never again. The ring of magnets in the Anker 622 MagGo aligns with the MagSafe magnets in every iPhone since the iPhone 12, latching securely and charging without wires. (The notable exception is the iPhone 16E, which does not offer MagSafe but does charge wirelessly using Qi technology. The Anker 622 MagGo will charge the iPhone 16E but won’t latch to it magnetically.)

It’s also compact — a little backpack feeding power to the phone while you’re holding it or have it stashed in a pocket, even a jeans pocket if your fit isn’t too tight.

Hey, did you know? CNET Deals texts are free, easy and save you money.

Those features alone would have convinced me but the Anker 622 also includes a fold-out back flap that props up my iPhone and can also hold the phone in its wide orientation for StandBy mode. With a power adapter such as the Anker Nano Pro (not included) and a charging cable, I’ve taught long classes with the phone angled to help me keep track of the time without checking my watch.

MagSafe-compatible charging

I’ve owned several battery chargers and each one has some sort of compromise. They’re bulky. They require a cable. They charge wirelessly but don’t include a magnet to keep the phone in place so it’s hard to maintain that connection. There’s always something.

The Anker 622 is half an inch thick and snaps onto the back of my iPhone using the MagSafe-aligned magnets. I don’t have to turn it on to start charging — power flows as soon as the connection is made.

Now, this isn’t the highest-capacity (5,000 mAh) or fastest portable charger. That’s fine. What I usually need is a way to eke out a few more hours of battery life on my iPhone. I can typically get a full top-off of my iPhone 15 Pro.

Making a stand

The other appealing feature of the Anker 622 MagGo for me is its built-in stand. Honestly, it doesn’t look like it should work well: It’s a fabric-covered set of plastic pieces that lie flush against the case, folds in two places and attaches to the back of the unit with a magnetic strip when extended. Yet I’ve had no problems with the stability of my iPhone 15 Pro or even the larger iPhone 15 Pro Max size.

This also lets me use standby mode by turning the iPhone to landscape orientation (the magnets are strong enough to hold the phone in place) when it’s on a table or desk.

Smart port placement matters

The charger gets its juice from a single USB-C port, which is positioned on the edge of the case, not the bottom. That means you can replenish it while the stand is open — many chargers’ ports are stuck on the bottom.

That USB-C port also acts as a charger for other devices when you plug in a cable, such as when your Apple Watch needs a boost.

How the Anker 622 MagGo compares to similar power banks

Before getting the Anker 622 MagGo, I carried an Anker PowerCore III 10K Wireless, which doubles the battery capacity, includes a USB-A port and charges wirelessly but without magnets to hold the phone in place. That meant if I didn’t use a cable, the phone and charger needed to be stable and level; too often I’d find the iPhone slid off its wireless perch and not charged. It’s also larger and heavier. I still use it, but it’s the power bank that goes into my carry-on suitcase as a backup charger.

Since I’ve owned this Anker 622 MagGo, the company has released a few updated models. The $60 Anker 633 packs 10,000 mAh into a thicker brick, includes a USB-A port in addition to USB-C and has a metal kickstand for resting the phone upright.

You can also consider getting the chunkier Anker MagGo Power Bank that delivers 10,000 mAh and follows the same idea of compact magnetic charging and a convenient kickstand. Its main appeals are faster 15-watt magnetic charging and Qi2 compatibility, plus a small display on the side that reports the battery capacity and an estimate of the remaining battery in hours.

(Note that some Anker power banks were part of a recent recall. Be sure to claim your free replacement or gift card if you own one of the affected devices sold between 2016 and 2022.)

TMR vs. Hall Effect Controllers: Battle of the Magnetic Sensing Tech

The magic of magnets tucked into your joysticks can put an end to drift. But which technology is superior?

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer meaningful edges when implemented properly. Hall effect and TMR (tunnel magnetoresistance or tunneling magnetoresistance) sensors are two such technologies. Hall effect sensors have found their way into a wide variety of devices, including keyboards and gaming controllers, including some of our favorites like the GameSir Super Nova.

More recently, TMR sensors have started to appear in these devices as well. Is it a better technology for gaming? With multiple options vying for your lunch money, it’s worth understanding the differences to decide which is more worthy of living inside your next game controller or keyboard.

How Hall effect joysticks work

We’ve previously broken down the difference between Hall effect tech and traditional potentiometers in controller joysticks, but here’s a quick rundown on how Hall effect sensors work. A Hall effect joystick moves a magnet over a sensor circuit, and the magnetic field affects the circuit’s voltage. The sensor in the circuit measures these voltage shifts and maps them to controller inputs. Element14 has a lovely visual explanation of this effect here.

The advantage this tech has over potentiometer-based joysticks used in controllers for decades is that the magnet and sensor don’t need to make physical contact. There’s no rubbing action to slowly wear away and degrade the sensor. So, in theory, Hall effect joysticks should remain accurate for the long haul.

How TMR joysticks work

While TMR works differently, it’s a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet in the vicinity of the sensor. So far, it’s the same, right? Except with TMR, this shifting magnetic field changes the resistance in the sensor instead of the voltage.

There’s a useful demonstration of a sensor in action here. Just like Hall effect joysticks, TMR joysticks don’t rely on physical contact to register inputs and therefore won’t suffer the wear and drift that affects potentiometer-based joysticks.

Which is better, Hall effect or TMR?

There’s no hard and fast answer to which technology is better. After all, the actual implementation of the technology and the hardware it’s built into can be just as important, if not more so. Both technologies can provide accurate sensing, and neither requires physical contact with the sensing chip, so both can be used for precise controls that won’t encounter stick drift. That said, there are some potential advantages to TMR.

According to Coto Technology, who, in fairness, make TMR sensors, they can be more sensitive, allowing for either greater precision or the use of smaller magnets. Since the Hall effect is subtler, it relies on amplification and ultimately requires extra power. While power requirements vary from sensor to sensor, GameSir claims its TMR joysticks use about one-tenth the power of mainstream Hall effect joysticks. Cherry is another brand highlighting the lower power consumption of TMR sensors, albeit in the brand’s keyboard switches.

The greater precision is an opportunity for TMR joysticks to come out ahead, but that will depend more on the controller itself than the technology. Strange response curves, a big dead zone (which shouldn’t be needed), or low polling rates could prevent a perfectly good TMR sensor from beating a comparable Hall effect sensor in a better optimized controller.

The power savings will likely be the advantage most of us really feel. While it won’t matter for wired controllers, power savings can go a long way for wireless ones. Take the Razer Wolverine V3 Pro, for instance, a Hall effect controller offering 20 hours of battery life from a 4.5-watt-hour battery with support for a 1,000Hz polling rate on a wireless connection. Razer also offers the Wolverine V3 Pro 8K PC, a near-identical controller with the same battery offering TMR sensors. They claim the TMR version can go for 36 hours on a charge, though that’s presumably before cranking it up to an 8,000Hz polling rate — something Razer possibly left off the Hall effect model because of power usage.

The disadvantage of the TMR sensor would be its cost, but it appears that it’s negligible when factored into the entire price of a controller. Both versions of the aforementioned Razer controller are $199. Both 8BitDo and GameSir have managed to stick them into reasonably priced controllers like the 8BitDo Ultimate 2, GameSir G7 Pro and GameSir Cyclone 2.

So which wins?

It seems TMR joysticks have all the advantages of Hall effect joysticks and then some, bringing better power efficiency that can help in wireless applications. The one big downside might be price, but from what we’ve seen right now, that doesn’t seem to be much of an issue. You can even find both technologies in controllers that cost less than some potentiometer models, like the Xbox Elite Series 2 controller.

Caveats to consider

For all the hype, neither Hall effect nor TMR joysticks are perfect. One of their key selling points is that they won’t experience stick drift, but there are still elements of the joystick that can wear down. The ring around the joystick can lose its smoothness. The stick material can wear down (ever tried to use a controller with the rubber worn off its joystick? It’s not pleasant). The linkages that hold the joystick upright and the springs that keep it stiff can loosen, degrade and fill with dust. All of these can impact the continued use of the joystick, even if the Hall effect or TMR sensor itself is in perfect operating order.

So you might not get stick drift from a bad sensor, but you could get stick drift from a stick that simply doesn’t return to its original resting position. That’s when having a controller that’s serviceable or has swappable parts, like the PDP Victrix Pro BFG, could matter just as much as having one with Hall effect or TMR joysticks.
