## At a glance

- Two built-in cables are advertised as Lightning and USB-C, reducing the need to pack separate charging leads.
- The listing describes a digital display, pass-through charging and a slim form factor.
- The stated 10,000mAh capacity is intended for portable backup charging, with the listing naming phones and other USB-C devices as compatible.

## Pros

- Built-in Lightning and USB-C cables can simplify carrying a charger for a mix of older Apple and USB-C devices.
- Compact listed dimensions and a 176 g listed weight make it a practical format for travel bags or pockets.
- Pass-through charging is claimed, allowing the bank and a connected device to charge together.

## Cons

- A 10,000mAh bank is a portable top-up option rather than a substitute for a larger-capacity power source on extended trips.

## Before you buy

- The listing is inconsistent about outputs and charging specifications. Its details table says 2 ports and 3 A, while feature text claims charging up to 4 devices simultaneously, 20W PD output and 18W USB-C input. It also gives thickness as both 0.6 and 0.61 inches, and recharge time as 3 hours without specifying conditions. Confirm the selected version's connections and charging rates before relying on those figures. The stated 50%-70% usable-capacity estimate is a listing claim, not a guaranteed number of device charges.

## A good fit for

- Travelers who want a compact backup battery with built-in Lightning and USB-C leads.
- People charging compatible phones or small USB-C devices who value a digital display and pass-through charging.

## Less suited to

- Buyers who need a confirmed multi-device output count or a clearly specified charging rate before purchase.
- People needing a high-capacity bank for prolonged off-grid use.

## Customer feedback

Customer feedback highlights perceived fast charging, compact size and travel convenience, with customers also mentioning the built-in Lightning and USB-C cords, display, light weight and compatibility across devices. These impressions fit the listed portable 10,000mAh format, but they do not resolve the conflicting output and charging-rate claims. Ratings are mostly five-star, with a smaller low-rating share, and the available rating data does not explain the reasons behind either view.
- Positive themes: Customers mention charging speed and compact size as useful qualities.
- Positive themes: Feedback notes the built-in Lightning and USB-C cords, digital display and portability.
- Positive themes: Customers describe the charger as versatile across older Apple devices and other USB-C peripherals.

## Frequently asked questions

### What capacity does the VIYISI G1212 list?
The specifications list a capacity of 10000 milliamp\_hours. The listing estimates that 50%-70% of that capacity may be delivered to other devices, so actual device charges depend on conversion losses and use.
### Which cables are built in?
The feature description claims one Lightning cable and one USB-C cable. The details table separately lists USB Type C as the connector type, so verify the cable arrangement on the selected listing if it is essential.
### Can it charge devices while the power bank is recharging?
Pass-through charging is claimed in the listing, but operating performance is not independently verified.
### How many devices can it charge at once?
The details table lists 2 ports, while feature text claims up to 4 devices at once using the built-in leads and USB-A and USB-C ports. The stated configurations conflict, so confirm the number of usable outputs before buying.
