Anker now has two of the MagGo Ultra Slim Qi2 power banks. There is a 5,000 mAh version and a 10,000 mAh version. Anker sent me both of these for free to review, and everything here is based on my own experience carrying and using each one. Side by side the 10,000 mAh model looks massive next to the 5,000 mAh model, but in real use the gap felt smaller than I expected. Here is how the two compare, and how I would pick between them.
Both are excellent slim Qi2 magnetic power banks. Get the 5K for the smallest, lightest everyday carry, and get the 10K when you want more charges before you have to plug it back in.
- Qi2 magnetic wireless charging with no cables needed
- Genuinely slim, the 5K barely sticks out past the camera bump
- Strong magnet that holds well on the back of the phone
- USB-C port for wired output and for recharging the bank
- Side button lights a battery indicator so you know what is left
- Available in several colors
- The 5K only recharges at up to 20 watts
- The 10K adds noticeable bump and weight when your case is off
- The 10K takes longer to recharge because of its larger battery
- The 5K gives only about two thirds of a full phone charge
Intro: Who This Is For
This one is for anyone who wants to top off their phone on the go without dealing with cables. Both of these attach magnetically to the back of your phone and charge it over Qi2, so you just slap it on and go. If you only need a small daily boost to get through the day, the 5K is probably your pick. If you travel a lot and want to go a couple of days without recharging the bank itself, the 10K makes more sense. I have used both, and below I break down where each one earns its place.
What Both Models Have in Common

These two are the same idea in two sizes. Both have the Qi2 pad on the back so you can magnetically attach them to your phone and charge wirelessly, no cable required. Both also have a USB-C port on the bottom, which you use two ways: to charge your phone hardwired, and to recharge the power bank itself with any USB-C charger. And both have a button on the side that lights up a battery indicator so you can see how much power is left. On top of that, each one comes in several fun colors.
Size and Feel: The Difference Is Smaller Than It Looks

The 10,000 mAh model is double the size of the 5,000 mAh model. It is not quite double the thickness, but it is close. Set them next to each other and the 10K looks huge. Here is the thing though: once you actually hold the phone and use it, the difference is pretty negligible, especially with a case on. When you take the case off and line them up side by side, that is when you really notice the size gap.
The 5K is the one that impressed me here. Without a case it just barely sticks out farther than the camera bump, and you almost forget it is on there. It has a really strong magnet too. I always thought the 10K felt pretty small for a Qi2 power bank, but once I started using the new 5K, I realized how much lighter and slimmer it really is. The 5K also seems to stay on the phone a little better.
How Many Charges You Actually Get
Capacity is the real reason to choose one over the other. The 5K gives you about two thirds of a full phone charge. The 10K gives you about 1 to 1.3 full phone charges for an iPhone 15 Pro. So the 5K is a daily top off that you plan on recharging every single day, and it is there to extend your phone life a bit. The 10K can give you roughly 40 to 80 percent of battery life and let you go a couple of days without plugging the bank back in.
Charging Speeds and Recharging

Both charge your phone over Qi2 when attached magnetically. If you go hardwired through the USB-C port, the 10K puts out up to 30 watts and the 5K puts out up to 20 watts, so wired is a little faster than the Qi2 mode on each.
Recharging the banks themselves works over USB-C with any USB-C charger. The 5K can only pull up to 20 watts to refill, while the 10K can pull up to 30 watts. Even with the faster input, the 10K still takes a bit longer to top off because it is a bigger battery.
Price

The 10K model typically goes for about $80, and the 5K goes for about $55. So you save a little money by going with the smaller one, on top of getting the slimmer package.
5K vs 10K: The Quick Comparison
Here is the head to head at a glance.
| 5K Ultra Slim | 10K Ultra Slim | |
|---|---|---|
| Capacity | 5,000 mAh | 10,000 mAh |
| Phone charges (iPhone 15 Pro) | About 2/3 of a charge | About 1 to 1.3 charges |
| Wired output | Up to 20 watts | Up to 30 watts |
| Recharge input | Up to 20 watts | Up to 30 watts |
| Size and feel | Slimmest, barely past camera bump | Noticeably bigger and thicker |
| Typical price | About $55 | About $80 |
Which One I Recommend
You should get the 5K if you just care about the smallest possible size and the convenience. Plan on charging it every single day and use it to extend your phone life. It is lighter, slimmer, takes up less space in a bag or a pocket, and it stays on the phone a little better. For most people who want something to throw in a bag, a purse, or keep stowed in a pocket, the 5K is the one I recommend.
Go with the 10K if you want to go a couple of days without recharging, or if you use it in short bursts and want to give your phone 40 to 80 percent more battery. If you are on the road a lot and always fighting to keep everything charged, you will appreciate the bigger one.
The Verdict

I really recommend both of these. Get the 5K if you want the slim, lightweight convenience of fast Qi2 charging and you do not mind topping it off daily. Get the 10K if you want a little more power so you do not have to charge it as often. For me, the 5K wins for everyday carry because of how little you notice it, but the 10K is the better call for travel.
