Ultra-thin wireless back clip battery for iPhone 12 models with polymer lithium ion technology

This wireless back clip battery provides iPhone 12 users with a discreet power solution that attaches directly to their device without creating excessive bulk. Measuring just 18mm thick, the ultra-thin TPU soft bag design houses advanced polymer lithium ion battery technology specifically calibrated for different iPhone 12 models. Available in black with a plastic outer shell, the battery features a practical multi-U port output system and clip-on attachment mechanism that makes it simple to add extended battery life to your mobile device when away from power sources.
Features and Construction

The back clip battery combines several functional elements into a cohesive design that prioritises slim proportions while delivering reliable power. Its construction focuses on compatibility with iPhone 12 dimensions and power requirements while maintaining a profile that doesn't interfere with everyday phone use.
Material and Build
The battery utilises polymer lithium ion technology housed within a TPU soft bag material that provides flexibility and protection for the internal components. This combination allows for the ultra-thin 18mm profile while maintaining the necessary battery capacity for iPhone 12 devices. The outer shell is constructed from durable plastic that forms the clip mechanism and provides structural support for the entire unit.
Size and Practical Fit
With dimensions measuring 167mm in length by 70mm in width, the battery is proportioned to match iPhone 12 models while leaving necessary clearances for buttons and ports. The 18mm thickness represents the slimmest dimension, allowing the battery to sit closely against the phone's back surface without creating noticeable protrusion. The clip mechanism securely attaches to the phone while the overall dimensions ensure balanced weight distribution.
Uses and Placement

This back clip battery serves as a practical power solution for various mobile situations where extended battery life is needed without access to traditional charging points. Its design specifically addresses the needs of iPhone 12 users who require additional power capacity throughout their day.
Event or Professional Use
For professional environments or event situations where charging opportunities are limited, the back clip battery provides reliable supplementary power. The multi-U port output offers flexibility for connecting different cable types, while the clip-on design means the battery stays securely attached during movement. The specific capacity allocations—4700mAh for iPhone 12 mini or 4800mAh for other iPhone 12 models—ensure appropriate power delivery for each device variant.
Everyday Home Use
In domestic settings, the battery serves as a convenient backup power source that eliminates the need to remain near wall outlets. The ultra-thin TPU soft bag construction makes it comfortable to hold while using the phone, and the black colourway maintains visual consistency with most iPhone 12 models. The clip mechanism allows for easy attachment and removal as power needs fluctuate throughout the day.
Benefits and Buying Value

This product offers practical advantages for iPhone 12 users seeking extended battery life without compromising their device's handling characteristics. The design focuses on compatibility, convenience, and proportional sizing that addresses common limitations of external battery solutions.
Reuse and Low Maintenance
The polymer lithium ion battery technology provides rechargeable capabilities that support repeated use cycles, while the TPU soft bag material offers protection against everyday wear. The multi-U port output accommodates various cable types, reducing the need for specialised adapters. The clip mechanism maintains its grip through regular attachment and removal cycles without requiring adjustment.
Why Choose This Product
This back clip battery distinguishes itself through its iPhone 12-specific design that includes model-appropriate power capacities and proportional dimensions. The ultra-thin 18mm profile represents a significant reduction in bulk compared to many external battery solutions, while the TPU soft bag construction provides durability without excessive weight. The integrated multi-U port output offers connection versatility that adapts to different charging cable requirements.
