About this guide: based on in-house product testing and specification review; confirm details with the supplier before ordering.
Capacity: what the mAh means
The mAh rating is the battery capacity of the power bank, not the amount that reaches the phone. Energy is lost in conversion, so a 10,000 mAh unit realistically delivers around two full charges to a typical phone, depending on the model and the cable.
| Capacity | Typical use |
|---|---|
| 5,000 mAh | Emergency top-up |
| 10,000 mAh | Daily phone charging |
| 20,000 mAh | Tablets, trips, multiple devices |
Match the capacity to the phone’s battery and the trip length rather than buying the largest unit, because size and weight grow with capacity.
Ports and protocols
Check the output ports and the charging protocols. A power bank with USB-C Power Delivery charges modern phones at full speed, while a unit with only USB-A output is slower on newer devices. Fast charging needs a matching cable and a phone that supports the protocol.
Wired vs magnetic wireless
Remax offers wired power banks and magnetic wireless models that attach to MagSafe-compatible iPhones. The magnetic models are convenient for a pocket, while wired models charge faster and work with every device. Choose by whether the power bank is a desk tool or a pocket companion.
Safety and genuine stock
Power banks contain lithium cells, so the safety certification and the supplier matter. Buy from a genuine channel: certified cells, documented capacity and a warranty protect against the failures that cheap lookalikes hide. Digi4u supplies Remax stock for retail and wholesale.
Power bank safety and travel rules
Power banks are lithium products, and the safety rules follow the cells. Keep the power bank out of direct sun and hot cars, store it away from metal objects and never charge it unattended in a bag. A swollen or hot unit should be retired, not used until it fails.
For travel, the rules are set by the airline and the UK carriage rules: power banks fly in hand luggage, not checked bags, and the watt-hour rating decides the limit. A 10,000 mAh unit is inside the common carry-on limits, while larger units need a check against the airline’s figure.
The certification is part of the safety story: certified cells, documented capacity and a warranty path protect the buyer. A power bank is a small device with a large energy store, and the source is the first safety feature.
Check the port, the protocol and the capacity before the purchase, and keep the unit out of hot cars. The Remax power bank range and the charger range at Digi4u cover the choices, and the source is the safety feature.

Digi4u product notes
Our bench rule: match the mAh to the trip, the protocol to the phone and the source to the certificate. A genuine 10,000 mAh unit beats a fake 20,000 mAh every time.

Frequently Asked Questions
How many charges does a 10,000 mAh power bank give?
Around two full charges for a typical phone, after conversion losses. The exact number depends on the phone and the cable.
Does a higher mAh charge faster?
No. Capacity and charging speed are separate: the mAh is the total energy, and the wattage decides the speed.
Is magnetic wireless charging slower than wired?
Usually yes. Wired charging delivers more power, while magnetic models trade speed for convenience.
