Feob 8600mAh Battery Charging Case for iPhone 12 Pro Max / 13 Pro Max / 14 Pro Max & 14 Plus (6.7 inch)
Quick take
The Feob battery charging case is designed to extend iPhone time on the go for select 6.7-inch models, using sync-through charging and 4 LED battery indicators to show remaining power. It is best for commuters and travelers who want to top up without carrying a separate power bank, but you must match the exact compatible iPhone model and you should expect wired charging only (wireless charging is not supported).
Pros and cons
Pros
- Made for specific iPhone 12 Pro Max, 13 Pro Max, 14 Plus, and 14 Pro Max (6.7-inch) compatibility
- 4 LED battery level indicators (25%, 50%, 75%, 100%) for at-a-glance power
- Sync-through design lets you charge the phone and the case together without removing it
- Claims 8600mAh capacity for longer day-to-day use and travel
Cons
- Does not support wireless charging, charging requires cables
- Compatibility is strict, it is not for mini or other Pro-sized iPhones
- Charging reliability is mixed in reviews, including reports that it stopped charging after a short time
What buyers think
Buyer-review evidence is mixed. Several reviews focus on the day-to-day convenience of extended battery life, an all-day experience for streaming, and the usefulness of the LED indicators. Other feedback indicates the case can stop charging after limited use, which is a meaningful risk to consider if your main priority is long-term charging reliability. Overall, buyers describe installation as straightforward and the case as fitting comfortably, but review evidence on performance consistency over many months is limited and not uniformly positive.
What this battery charging case does well
This is a battery case, meaning it is built to do two jobs at once: protect the phone and provide extra charging capacity while the phone stays in the case. For people who regularly run out of battery away from outlets, the practical benefit is less hassle. The design also includes a sync-through approach, so you can charge both the iPhone and the battery case without removing the device.
Compatibility you should double-check first
Before buying, confirm you have one of these supported models: iPhone 12 Pro Max, iPhone 13 Pro Max, iPhone 14 Plus, or iPhone 14 Pro Max (6.7-inch). The case is not intended for iPhone mini models or other 6.1-inch Pro models, and it is not for the iPhone 15 series. If you buy for the wrong model, you risk a poor fit or unusable charging setup.
Battery level visibility with the 4 LED indicators
The included 4 LED battery indicators (labeled at 25%, 50%, 75%, and 100%) help you decide when to plug in. This is a common pain point with portable chargers, because you do not always know how much power you have left. Here, you can get a quick read without guessing.
Designed for daily travel and outlet-light routines
Designed to be portable and easy to use, it is positioned as a travel-friendly way to keep your phone working during long days, commutes, or outdoor plans. The case also includes protective design elements intended to help guard the phone from everyday bumps and scratches.
Key limitations to know before you buy
Wireless charging is not supported
If you rely on MagSafe or other wireless charging pads, this case does not support that. Charging is wired, and the case also needs to be fully charged when you first start using it. If wireless charging convenience matters to you more than extra capacity, you may want to compare alternatives that support wireless charging.
It is not waterproof
The case is not designed for wet environments. If the battery case gets wet, it should be left to dry before use.
Long-term charging reliability has mixed review signals
Most positive review themes center on staying powered through the day, but there is at least one significant negative theme: the case stopped charging after relatively short use. Review evidence overall suggests performance can be strong, but consistency over time is not guaranteed by the available comments. If you are sensitive to downtime, consider that risk and check the return policy before committing.
Pros and cons for different types of buyers
Best for
- Owners of supported 6.7-inch iPhones who want an always-on battery boost
- Road warriors and travelers who prefer charging the case at night and using it all day
- People who like clear battery visibility (the LED indicator approach)
Not ideal for
- Anyone who needs wireless charging support (MagSafe or charging pads)
- Buyers with iPhone models outside the strict supported list
- Shoppers who cannot tolerate potential early failures or short-term charging issues
How it compares to other approaches (what to prioritize)
- Compared with a power bank + phone case: A battery case is simpler day-to-day since charging happens while the phone is in the case. The tradeoff is stricter compatibility and more device bulk.
- Compared with wireless-charging-friendly battery cases: This one is better if you are fine with wired charging. It is a mismatch if wireless charging convenience is a must-have.
- Compared with standard protective cases plus charging accessories: If your main goal is more battery capacity rather than just protection, a dedicated battery case can reduce the number of items you carry, but you are locking into a specific phone model.
Bottom line verdict
The Feob battery charging case is a good option for the right iPhone models (select 6.7-inch variants) if you want extended day-long power, easy LED battery visibility, and sync-through wired charging convenience. The biggest buying caveats are its strict compatibility, lack of wireless charging support, and mixed signals about charging reliability over time.
