Essager’s cleaner take on pocket charging
Essager has built a solid reputation in the AliExpress power bank niche by focusing on practical hardware rather than flashy extras. This model follows that pattern with a slim metal body, magnetic alignment, and charging specs that make sense for daily carry instead of desk-only use.
It is the kind of accessory that solves a simple problem: how to keep an iPhone topped up without adding much bulk to the phone itself. The 13.5mm profile and 108.4 x 66mm footprint suggest a design meant to disappear into a pocket or small sling bag, so what does that mean in real use?
13.5mm thickness: why the shape matters more than the number
At 13.5mm thick, this power bank is slim enough to feel manageable when attached to the back of a phone, especially compared with older brick-style battery packs. The metal shell should also help it feel more rigid in hand, which matters when you are stacking a phone, case, and charger into one compact unit.
Users commonly mention that the unit feels thin for its capacity, and that impression lines up with the dimensions on paper. The trade-off is simple: you get a more portable battery, not a featherweight one, so the next question is how much charging performance it actually delivers.
20W wired output and wireless charging: what you can expect

The USB-C port supports up to 20W output, which is enough for fast top-ups on modern iPhone models and a useful fallback when wireless charging is not ideal. The wireless side is rated at 7.5W or 15W, so it is better suited to convenient topping up than to the fastest possible charging session.
Its charging distance is listed at 5mm or less, which means slim cases are the safer match if you want stable magnetic contact. According to users, the magnet holds firmly and the charge remains stable, which is exactly what matters when you are walking, commuting, or using the phone one-handed.
10,000mAh capacity: enough for a full day out
With 10,000mAh on board, this power bank is aimed at one to two meaningful phone charges rather than emergency micro-boosts. Real-world feedback suggests it can comfortably carry a phone through a long day, and some users report enough reserve for more than one recharge depending on the device.
The energy conversion rate is listed at 70% or higher, which is typical for compact lithium-polymer packs and reminds buyers not to expect the full rated capacity at the phone end. That is still a practical amount for travel, workdays, and event use, especially when the alternative is hunting for a wall socket.
Metal shell, safety protection, and the small details that matter

The metal casing gives the product a more premium feel than soft-touch plastic competitors, and it should resist scuffs better in a bag with keys or cables. Protection features include temperature control at 60°C and over-voltage protection at 13.2V, which adds a reassuring layer for regular everyday use.
It also supports two-way quick charge through USB-C, so the same port handles both input and output, reducing cable clutter. That makes it a neater choice than older multi-port battery packs, and the included LED lamp feature adds a small but useful utility for low-light situations.
Who this power bank suits best
This model makes the most sense for iPhone users who want a magnetic attachment experience without moving to a bulkier charging stand. It is also a sensible pick for people who value a clean look, since the gray finish and compact shape give it a restrained, modern feel rather than a gadget-heavy appearance.
For Android users, the wireless function still works within the supported standard, but the magnetic convenience is less central unless the phone case is compatible. Customers have described the build as well made and the charging as quick, which supports the idea that this is a dependable travel companion rather than a novelty accessory.
