# TRKOY 45W 20,000mAh Portable Power Bank

TRKOY's 45W portable power bank pairs a listed 20,000mAh capacity with a built-in USB-C cable for phone top-ups away from an outlet. Its compact dimensions and fast-charge claims suit travel and everyday carry, though the listing is inconsistent about its ports and how many devices it can charge at once.

## Before you buy

- The listing is inconsistent about connections and simultaneous charging: specifications state 2 ports, while feature text describes one USB-C and one USB output, two built-in Type-C cables, and charging up to four devices. Confirm the selected unit's actual ports, cables and simultaneous output before buying. Its claims of 45W charging, up to four iPhone 15 charges, and 35% smaller size are listing claims, not independently verified results. The page also gives different service periods, stating 1 Year in details and 3 years in product copy.

## A good fit for

- Travelers and commuters seeking a high-capacity phone power bank with a built-in cable.
- Phone users who want a displayed remaining-charge estimate and claim-supported fast charging.

## Less suited to

- Buyers who need confirmed multi-device simultaneous charging or a clearly specified port layout.
- People seeking an independently verified charging rate or real-world number of device recharges.

## Customer feedback

Customer feedback highlights perceived capacity, compactness, portability, the built-in cable and quick phone top-ups. Those reports align with the power bank's intended everyday and travel use, but do not establish a measured charging rate or confirm the listing's disputed cable and multi-device configuration. The aggregate ratings are strongly positive overall, while a smaller share of ratings is less favorable, and ratings alone do not explain why.
- Positive themes: Customer feedback praises the perceived battery capacity and quick phone top-ups.
- Positive themes: Customers also praise its compact size, portability and built-in cable.

## Frequently asked questions

### Does the TRKOY power bank have a built-in cable?
Yes. The listing claims a built-in USB-C cable. It also describes two Type-C cables in feature text, so confirm the exact cable arrangement on the selected listing.
### How many devices can it charge at the same time?
The page claims up to four devices but also lists two ports and gives differing descriptions of its cables and outputs. The simultaneous charging arrangement is unconfirmed.
### Is 45W charging guaranteed for every phone?
No. The listing claims 45W and PD/QC support, but charging speed depends on the connected device and conditions. The listed claim is not an independent measurement.
### How many phone charges should I expect?
The listing claims up to four charges for an iPhone 15, but actual recharges vary by phone and usage. It also notes that conversion losses reduce usable capacity.
