Best MagSafe Battery Packs For iPhone 17 (2026)
A MagSafe-style battery pack snaps onto the back of an iPhone 17 and charges it wirelessly, so you can top up without carrying a cable.
These five picks are all current, magnetic and sized for a pocket, and they differ mainly in capacity, thickness and how much detail the makers publish.

Why most wireless speeds here top out at 15W
Anker’s iPhone 17 charging guide says the iPhone 17, 17 Pro and 17 Pro Max can reach up to 25W on MagSafe or Qi2 chargers, while the iPhone Air is capped at 20W.
Four of the five packs below list a wireless output of up to 15W, so expect a slower top-up than a wall-powered 25W charger gives you, and only the Anker MagGo 2 Pro lists 25W.
That is normal for a pocket battery, and it keeps heat and bulk down.
1. Anker Nano Power Bank (5K, MagGo, Slim): slimmest pick
This is the thinnest and lightest pack here, which makes it the easiest one to leave attached all day.
Specs: 5,000mAh | up to 15W wireless | 0.34 in (8.6 mm) thick | 122 g | $54.99 Anker list price
Pros:
- Very thin at 8.6 mm.
- Anker lists 15W wireless output for MagSafe-compatible iPhones.
Cons:
- Anker says real output is about 2,750 to 3,500mAh after energy loss.
- Cards, keys and metal attachments can interfere with charging.
2. Baseus PicoGo 10,000mAh Qi2: most capacity
The PicoGo doubles the capacity of the Anker Nano while staying under 15 mm thick.
Specs: 10,000mAh | Qi2 up to 15W wireless | one USB-C port up to 27W | 14.9 mm thick | 172 g
Pros:
- 10,000mAh is enough for more than one top-up.
- 27W USB-C helps when you charge a second device by cable.
Cons:
- At 172 g it is noticeably heavier than the 5K packs.
- Baseus does not list an included cable on this model, since the built-in-cable version is a separate model.
3. Anker MagGo Power Bank (10K, Slim): 10K from Anker
This is Anker’s slimmer 10,000mAh option, and it adds a USB-C port that is rated higher than the Nano’s.
Specs: 10,000mAh | 5W, 7.5W or 15W wireless | USB-C up to 30W | 0.58 in (14.7 mm) thick | 7.62 oz (215.9 g)
Pros:
- 10,000mAh in a pack under 15 mm thick.
- High USB-C rating for charging other devices.
Cons:
- At 215.9 g it is the heaviest pick here.
- Anker’s page does not state Qi2 certification and shows a lower total-output figure next to the 30W claim.
4. TRKOY W5 5000mAh: thin 5K alternative
The W5 is a 5,000mAh magnetic pack aimed at iPhone 12 through 17 owners who want something small.
Specs: 5,000mAh | magnetic wireless, wattage not listed | USB-C 5V/3A | 11.8 mm thick | 15N magnet
Pros:
- The listing states a 15N magnetic force.
- Thin at a listed 11.8 mm.
Cons:
- No wireless wattage or Qi2 certification is listed in the retailer page we checked.
- The listing gives conflicting weight (120 g and 130 g) and thickness figures, so confirm them before you buy.
5. Anker MagGo 2 Pro (10K, Qi2 25W): fastest wireless
This is the only pack here that lists 25W wireless output, and it adds a fan and a status display.
Specs: 10,000mAh | Qi2 25W wireless | 45W USB-C two-way | 0.7 in thick | 7.76 oz | 9to5Mac lists $109.99
Pros:
- Anker says it can take an iPhone 17 Pro to 50% in about 25 minutes, according to 9to5Mac.
- Active cooling, a built-in kickstand and a display for battery level, speed and temperature.
Cons:
- At 7.76 oz and 0.7 in it is the heaviest and thickest pack on this list.
- Anker’s product page does not state iPhone 17 compatibility, so check that your model and case suit a Qi2 25W pack.
How do they compare side by side?
| Product | Capacity | Wireless | USB-C | Thickness | Weight |
|---|---|---|---|---|---|
| Anker Nano 5K | 5,000mAh | Up to 15W | Not clearly stated | 8.6 mm | 122 g |
| Baseus PicoGo | 10,000mAh | Qi2 up to 15W | Up to 27W | 14.9 mm | 172 g |
| Anker MagGo 10K Slim | 10,000mAh | Up to 15W | Up to 30W | 14.7 mm | 215.9 g |
| TRKOY W5 | 5,000mAh | Not listed | 5V/3A | 11.8 mm (listed) | 120 g or 130 g (listed) |
| Anker MagGo 2 Pro | 10,000mAh | Qi2 25W | 45W two-way | 0.7 in | 7.76 oz |
How do you choose the right one?
Start with the capacity number, but remember that makers list the battery rating, not what reaches your phone.
Anker says the 5,000mAh Nano delivers about 2,750 to 3,500mAh and the 10K MagGo about 6,000 to 7,000mAh once energy loss is counted.
- Thin and light: pick a 5K pack for a quick top-up.
- All-day or travel use: pick a 10K pack and accept the extra weight.
- Charging other gadgets: compare the USB-C ratings in the table.
Anker also warns that cases thicker than 2.5 mm can weaken the magnetic connection, so a slim case helps the pack stay attached.
Why is Apple’s MagSafe Battery not on this list?
Apple’s support page says its MagSafe Battery was created exclusively for iPhone Air, and it lists iPhone Air as the only compatible phone.
Apple’s page offers up to 12W of wireless charging on iPhone Air and does not mention iPhone 17.
For an iPhone 17, the third-party packs above are the safer choice.
Which one should you buy?
Buy the Anker Nano if you want the thinnest pack that stays on your phone all day.
Buy the Baseus PicoGo if you want 10,000mAh with a 27W USB-C port.
Buy the Anker MagGo 2 Pro if you want the fastest listed wireless speed and can live with the extra bulk.
