Key Features
-
Magnetic wireless charging: Thanks to the built-in MagSafe-compatible alignment magnetics, the device snaps securely to the back of your iPhone (12 series and later) allowing wireless power delivery up to 7.5 W. Anker Singapore+1
-
Wired USB-C support: In addition to wireless, you get a USB-C output (max 12 W, 5 V/2.4 A) to charge non-magnetic devices or to top up the power bank itself. Anker Singapore
-
Portable capacity: With 5,000 mAh of battery capacity, it provides a meaningful boost to your device when you’re away from the wall outlet — for example, up to ~19 hours extra video playback on an iPhone 14 Pro Max (as stated by Anker). Anker Singapore
-
Durability & safety: The battery is designed to retain ~90% of its capacity after 20 months of use (according to Anker), outperforming typical industry standards. It also features temperature-monitoring sensors to maintain safe charging conditions. Anker Singapore
-
Universal MagSafe compatibility: Works with iPhones that support MagSafe (12/13/14/15) and wireless charging cases; note: non-magnetic or very thick protective cases may reduce the magnet hold or wireless performance. Anker Singapore+1
Why It’s Good
-
Convenience: You don’t have to fumble with wires each time you need a top-up—just snap your phone on the back and go.
-
Portability: Its compact size makes it ideal for commuting, travelling, or everyday carry in a bag or jacket pocket.
-
Brand reliability: Anker has a solid reputation for build quality and after-sales support; you’re choosing more than just specs.
-
Safety-focused: Good heat / temperature management makes it safer than many generic power banks.
Good to Know / Points of Attention
-
Capacity limitations: At 5,000 mAh, this power bank won’t fully recharge larger phones more than once. Expect maybe ~0.6-0.8 full charges depending on your phone and usage. Anker Singapore
-
Wireless speed capped: The wireless output is up to 7.5 W max (in this model) — not as fast as some larger/premium magnets which support 15 W wireless.
-
Case and accessory impact: If your phone case is non-magnetic, extremely thick, or has metal/attachments on the back, the magnet hold or wireless functionality may be disrupted.
-
Wired output modest: The USB-C output is only up to ~12 W, so if you’re looking for very fast wired charging of e.g. a tablet, you may wish to supplement with a higher-output charger.
