During an outage, the same question often comes up: which device gets the remaining charging energy? A radio with a power-bank function gives you another option, but it doesn’t make that decision disappear.

The Midland ER310PRO Portable Emergency Crank Radio with Power Bank pairs emergency listening with a crank and charging capability. I’d compare it for someone who wants those functions grouped in one identifiable household item.

Decide What the Radio Is Responsible For

If the ER310PRO is your main way to hear local updates, preserve enough energy for that role. A phone charging from the receiver can be convenient while also reducing what remains available for listening.

Model: Midland ER310PRO.
Core format: Portable emergency crank radio.
Additional function: Power bank.

Crank Power Is Another Route

The crank gives you a backup input to learn, rather than a reason to stop charging the unit normally. Follow the current manual for how to use it and what maintenance the battery needs between outings.

I’d keep the proper cable alongside the radio and make the storage place obvious to the rest of the household. A useful charger in an unknown drawer isn’t much help.

Compare the PRO Version Precisely

Similar Midland model names can make it tempting to transfer specifications from one receiver to another. Check the ER310PRO’s actual battery, outputs, alert behavior, and box contents before comparing prices.

That is especially worthwhile if phone charging is a major reason you’re considering this version over a smaller receiver.

Keep a note of which cable fits the radio and which output is intended for another device; similar-looking connectors can create avoidable confusion.

My Take

I’d compare it for a shared emergency-information setup where a power-bank function adds convenience. For several phones or repeated recharging, separate battery storage may be more flexible. The recommendation doesn’t claim personally measured charging output, crank performance, or reception.
