# Charmast CMA Mini USB-C Power Bank, 5000mAh

Mini: Charmast CMA is a compact 5000mAh power bank with a built-in USB-C connector for topping up compatible USB-C phones without carrying a separate charging cable. Its small claimed capacity suits emergency or short-trip backup rather than buyers seeking a high-capacity multi-charge pack.

## Before you buy

- The listing details are inconsistent: the title and feature copy claim 20W PD and 18W QC, while other details give 12 Volts, 1.6 Amps, two ports and a 1.5 Amp Hours charge-time entry. Listed dimensions of 4 x 4 x 25 millimetres also differ from the feature copy's 77.2 × 35.0 × 24.7 mm, and model information is given as both CMA and galaxy,galaxys10. Confirm the selected version's connector, charging output, dimensions and phone compatibility before buying. The claimed 1.5-hour recharge specifies a 9V-2A charger.

## A good fit for

- USB-C Android phone owners wanting a small backup charger for commuting or short outings.
- Buyers who value a built-in charging connector and do not want to pack a separate cable.

## Less suited to

- iPhone users, as the listing says this CMA version is not for iPhone.
- Buyers needing a high-capacity pack for several full charges or extended time away from a mains supply.

## Customer feedback

Customer feedback highlights the compact size, portability and convenience for travel, while reported charging speed and reliability are mixed. Some customers say it charges a phone fully, while others report only a partial charge or that the unit stops working. Durability concerns and divided views on value also appear. That feedback matters for a small 5000mAh backup pack: the form factor suits carrying for occasional top-ups, but reports do not establish consistent output or long-term reliability.
- Positive themes: Customers describe it as compact, portable and convenient to carry for travel.
- Negative themes: Some customers report durability problems, including units breaking within five months.
- Mixed feedback: Reports on charging speed and reliability vary, from full phone charges and good operation to partial charging or the unit stopping working.
- Mixed feedback: Opinions on value are divided.

## Frequently asked questions

### Does this power bank work with iPhones?
The listing says this CMA version is for Android phones with a USB-C interface and is not for iPhone. Check connector and device compatibility before ordering.
### Does it include a charging cable?
The power bank is described as having a built-in USB-C connector for charging a phone directly, so a separate phone cable is not needed for that connection. The package contents are not specified.
### How many phone charges can 5000mAh provide?
The listing estimates around 0.8–1.2 charges for an Android phone. Actual results depend on the phone and usage.
### How long does it take to recharge the power bank?
The feature copy claims about 1.5 hours using a 9V-2A quick charger. Other listed charging details are inconsistent, so confirm the required input and charger for the selected version.
