There is no verified set of 13 distinct Anker-family gadgets in the available product information, so padding this roundup to match the original count would be misleading. These six compact picks have model-specific details that make their carry size and purpose easier to assess. The dimensions, weights, capacities and output ratings below are manufacturer specifications, not independent test results.
How to choose a genuinely compact gadget
“Mini” can mean a small plug-in charger, a light power bank, or a thin magnetic battery that takes up little depth but spans much of a phone’s back. Compare dimensions and weight alongside capacity, output, connectors and your device’s compatibility. Manufacturer ratings describe maximum output under specified conditions; they do not guarantee that every device will charge at that rate.

Compact Anker power banks
Anker Nano Power Bank A1653: light and built to plug into USB-C
Anker lists the A1653 at 5,000mAh, 3.5 ounces and 3.03 × 1.45 × 0.98 inches, with a foldable built-in USB-C connector and up to 18W total output. It suits someone who wants a small backup bank without packing a separate cable for a compatible USB-C device. For listed iPhone generations, Anker says to use a separate USB-C-to-Lightning cable. The connector is not compatible with phone cases thicker than 0.19 inches (4.9mm); Anker also advises holding the phone and bank while charging because the connector folds into the device. Check the A1653 product page for its device-family compatibility details.

Anker Nano Power Bank A1638: more capacity and a retractable cable
The A1638 has 10,000mAh capacity, measures 3.21 × 1.99 × 1.42 inches and weighs 0.51 pound, according to Anker. Its built-in retractable USB-C cable and USB-A port reduce the need to carry a charging lead, while the USB-C path is rated for up to 45W. This is the larger, heavier choice over the A1653, with twice the stated capacity and a higher USB-C output ceiling. Confirm your device’s charging requirements and the model’s current availability on Anker’s A1638 page.

Portable soundcore speakers: check the exact model
soundcore’s mini-speaker collection includes models such as the Select 4 Go and Boom Go 3i and describes the category as “pocket-sized, travel-friendly.” A collection page is not enough to compare an individual speaker’s dimensions, battery life or water resistance: those claims vary by model. Check the selected speaker’s own item page for those specifications rather than assuming a category-level figure applies to every product.
