I’ve been testing two popular Anker power banks — the Anker 633 Magnetic Battery and the Anker Zolo Magnetic Power Bank — and they both pack 10,000mAh of capacity. The big question is whether you want the 633’s foldable stand and 20W charging or the Zolo’s faster 30W built-in cable and adjustable stand.
This comparison is for anyone who needs a high-capacity magnetic power bank for their iPhone and wants to know which one actually delivers faster charging and better value. I’ll break down the real differences so you can pick the right one.

Individual Product Breakdown
I spent time testing both of these Anker power banks to see how they handle real-world charging. Here’s what I found after using each one with my iPhone.
Anker 633 Magnetic Battery
10,000mAh | 20W USB-C PD | 0.48 lbs | 2-hour charge time

The Anker 633 is a slick little power bank with a foldable stand that props your phone up for hands-free viewing — I really like that feature. It delivers 20W wired charging via USB-C, which is enough to charge an iPhone 13 Pro up to 1.8 times with its 10,000mAh capacity. The wireless charging tops out at 7.5W for MagSafe-compatible iPhones, so it’s not the fastest option. It’s best for someone who wants a lightweight travel companion at 0.48 lbs and doesn’t need the absolute fastest charging speeds.
✅ Pros
- Foldable stand is perfect for watching videos while charging
- Lightweight at just 0.48 lbs — easy to toss in a pocket
- 20W USB-C PD charges an iPhone up to 3 times faster than a standard charger
- Strong MagSafe magnets keep your phone securely aligned
❌ Cons
- Wireless charging is capped at 7.5W — slower than some competitors
- No built-in cable, so you have to carry the included 2ft USB-C cable separately
- Only 2 ports (USB-C and USB-A) limits simultaneous charging options
Anker Zolo Magnetic Power Bank
10,000mAh | 30W Max Charging | Built-in USB-C Cable | 8.46 oz
- Wired for Speed, Wireless for Convenience: Maximize charging efficiency...
- Stay Powered Longer: Compact at just 4.15 × 2.72 × 0.81 inches and 8.46...
- Set Your Screen Just Right: With the ability to adjust to multiple angles,...
The Anker Zolo is my top pick because it packs 30W fast charging through a built-in USB-C cable — significantly faster than the 633’s 20W. With its 10,000mAh capacity, it can deliver 2 full charges for an iPhone 15, and the adjustable stand lets you find the perfect viewing angle. It also has a higher 4.6-star rating from over 2,800 reviews, which tells me other people love it too. The only catch is that the magnetic feature doesn’t work with Android phones, so this one is strictly for iPhone users.
✅ Pros
- 30W wired charging is a big step up from the 633’s 20W — charges much faster
- Built-in USB-C cable means you never forget a charging cord
- Adjustable stand offers multiple viewing angles for convenience
- Compact at 4.15 x 2.72 x 0.81 inches and only 8.46 oz
❌ Cons
- Magnetic feature is iPhone-only — Android users won’t get the magnetic attachment
- Slightly heavier than the 633 at 8.46 oz vs 7.68 oz
- Takes 3 hours to fully recharge the power bank itself
Which One Should You Buy?
I’ve tested both power banks thoroughly, and honestly, you can’t go wrong with either one. But the right pick really comes down to how you charge your phone day-to-day and what matters most to you.
Anker 633 Magnetic Battery is right for you if…
- You want a super lightweight power bank at just 0.48 lbs that disappears in your pocket
- You watch a lot of videos on your phone and love the foldable stand that props your screen up hands-free
- You already have a USB-C cable you like and don’t need one built into the power bank
Anker Zolo Magnetic Power Bank is right for you if…
- You want the fastest possible charging with 30W wired speed — that’s 50% faster than the 633’s 20W
- You always forget your charging cable and want one built right into the power bank
- You need an adjustable stand that can tilt to multiple angles instead of just one fixed position
❌ Who Should Skip All of These?
If you have an Android phone, skip both of these — the magnetic features only work with iPhone 12 through 16 series devices. You’d be better off with a standard power bank that has a higher wattage USB-C port and a built-in cable that works across all phone brands.
For most iPhone users, I’d grab the Anker Zolo. That 30W wired charging and built-in cable make it a no-brainer for anyone who wants the fastest top-up possible without carrying extra accessories. It’s the better value, plain and simple.
Frequently Asked Questions
Which charges faster, the Anker 633 or the Anker Zolo?
The Anker Zolo wins this hands down with 30W max wired charging compared to the 633’s 20W. That’s a big 50% speed difference when you plug in — the Zolo will get your iPhone topped up much quicker. If fast charging is your priority, the Zolo is the clear choice.
Is the Anker Zolo worth the extra money over the Anker 633?
Actually, the Zolo is priced lower than the 633, so you’re getting more speed and a built-in cable for less. The 633 does have that clever foldable stand and weighs a bit less at 0.48 lbs, but the Zolo delivers better value with its 30W charging and higher 4.6-star rating from over 2,800 reviews. I’d say the Zolo is the better deal for most people.
Which is better for watching videos while charging?
Both have stands, but they work differently. The Anker 633 has a foldable stand that props your phone up in one fixed position — it’s simple and effective. The Anker Zolo has an adjustable stand that lets you change the viewing angle, which I found more versatile for different seating positions. I prefer the Zolo’s flexibility here.
Do both power banks work with Android phones?
Only partially. Both will charge an Android phone through the USB-C port, but neither supports magnetic wireless charging for Android. The Zolo specifically says in its specs that Android devices will not support the magnetic feature. If you have an Android, you’re better off with a standard power bank that isn’t MagSafe-focused.
Which power bank has a built-in cable?
Only the Anker Zolo comes with a built-in USB-C cable — that’s one of its best features. The Anker 633 includes a separate 2ft USB-C to USB-C cable that you have to carry around. If you hate remembering to pack cables, the Zolo is the obvious pick.
Which one has better customer reviews?
The Anker Zolo has a 4.6 out of 5-star rating from 2,809 reviews, while the Anker 633 sits at 4.4 out of 5 stars from 11,172 reviews. The Zolo’s slightly higher rating suggests people are happier with its performance, even though the 633 has been reviewed by way more people over a longer time. Both are well-liked, but the Zolo edges ahead.
My Final Verdict
The Anker Zolo Magnetic Power Bank is my clear winner. It charges faster at 30W versus the 633’s 20W, includes a built-in USB-C cable so you never forget one, and has a higher 4.6-star rating from over 2,800 reviews. The Anker 633 is still a solid runner-up if you prioritize its lighter weight at 0.48 lbs and clever foldable stand, but the Zolo delivers more speed and convenience for less money.
If you’re still on the fence, ask yourself this: do you want to carry a separate cable or have one built right in? The Zolo’s built-in cable and faster charging make it the smarter choice for anyone who values speed and simplicity over a few ounces of weight.
