AI Verdict
A 10000mAh power bank with built-in Lightning, USB-C, and Micro-USB cables, plus 3 additional outputs, for users prioritizing cable-free convenience on a budget.
This 10000mAh power bank is a situational fit, primarily for its built-in cables that simplify carrying for light daily use or short trips. However, its reported slow charging speeds for devices and long recharge times for the unit itself mean it won't keep up with demanding users or those needing quick power boosts. The convenience of integrated cables is its main draw, but it comes with compromises in performance and durability.
If you need faster charging and more robust build quality, look for power banks with higher wattage USB-C PD (Power Delivery) output and input specifications, and consider models from brands known for durability.

What Buyers Say
While this Charmast power bank boasts a 4.5/5 rating from over 18,000 reviews, a deeper look reveals consistent issues despite its popularity. The main draw is definitely the built-in cables, which many users find incredibly convenient for travel and daily carry, eliminating cable clutter. However, a significant number of buyers report surprisingly slow charging for their devices, making the '3A Fast Charging' claim questionable in practice. The power bank itself also takes a long time to recharge, and some users have experienced durability problems with the built-in cables and casing after a short period of use.
âUgh, I bought this for the built-in cables and they're super handy, but my phone charges SO SLOWLY and the power bank dies way faster than I thought it would. My USB-C cable already feels flimsy after a month. So annoying!â
Common Praise
- The built-in Lightning, USB-C, and Micro-USB cables are incredibly convenient, removing the need to carry separate cords.
- The slim profile (5.68''x2.63''x0.69'') and light weight (0.53lb) make it easy to carry in a pocket or small bag.
- The digital LED display showing exact battery percentage is helpful for knowing when to recharge.
- The ability to charge up to 6 devices simultaneously is useful for multi-device users.
- It's widely compatible with various phones and tablets, including iPhone, Samsung, and Google Pixel.
Common Complaints
- Device charging is often much slower than expected, with a Samsung S25 Ultra taking 4 hours for a full charge.
- The power bank's internal battery drains too quickly, sometimes after only one device charge.
- Recharging the power bank itself can take an excessive amount of time, over 10 hours for a full charge.
- Built-in cables, particularly the USB-C, have been reported to break or fall apart after a month of use.
- Some units arrive with an unexplained 'E8 error code' right out of the box, indicating a fault.
- The plastic casing has been reported to break or show poor durability.
Ownership Tips
- The '3A Fast Charging' claim doesn't translate to actual fast charging speeds for devices in real-world use.
- The convenience of built-in cables might be short-lived due to reported durability issues with the cables themselves.
- You'll need to factor in long recharge times for the power bank, often requiring an overnight charge.
- The 10000mAh capacity might not provide as many full charges as expected due to efficiency losses or fast self-drain.
- Be prepared for potential quality control issues like an 'E8 error' on arrival.

Is this power bank airline approved?

The power bank features a digital LED display that shows the accurate percentage of remaining battery life.

Buying Guide
When you're looking at a portable charger, you're really buying convenience and extra juice for your gadgets. Don't just look at the big 'mAh' number; think about how many devices you need to charge and how quickly. Built-in cables are a huge plus for avoiding clutter, but check if they're durable. Also, consider how fast the power bank itself recharges, because nobody wants to wait all day for their charger to be ready.
Battery Capacity (mAh)
This number, like 10000mAh, tells you how much energy the power bank can store. Think of it like the size of a gas tank for your phone; a higher mAh means more charges for your devices before the power bank needs refilling. For reference, most smartphones have batteries between 3000-5000mAh.
Outputs and Inputs
Outputs are the ports or cables you use to charge your devices (like your phone). Inputs are how you recharge the power bank itself. More outputs mean you can charge more gadgets at once, and multiple input options give you flexibility for recharging the power bank with different cables you might already have.
Built-in Cables
This is a convenience feature. Instead of carrying separate USB-C, Lightning, or Micro-USB cables, they're integrated directly into the power bank. This reduces clutter and ensures you always have the right cable for your devices, but their durability is key.
Alternatives
If this power bank doesn't quite fit, look for models with higher wattage USB-C Power Delivery (PD) for faster device charging and quicker power bank recharging, or consider a larger capacity (e.g., 20000mAh) if you need more charges for multiple devices over longer periods.
