Expanded out of Taiwan, Sangean today is well-renowned for producing a wide variety of durable radios, including utility, portable, and emergency radios. As a company, they aim to improve radio communications with quality reception and reliability.

Weighing only 13.8 ounces, the Sangean MMR-88 is the better option if you’re looking for an ultra-portable radio that won’t weigh down your bag or pockets. When camping or backpacking, weight can be an important factor considering all of the equipment you may have to carry with you.

While it doesn’t have an ultrasonic dog whistle or an intensely bright flashlight, the Sangean features an emergency buzzer and built-in loudspeaker so that you can alert search and rescue teams of your location in life-endangering situations.

Also, the Sangean features a 90-minute automatic shutoff feature to save battery, which is a stand-out feature that the Midland lacks. The Sangean also is IPX3 rated so that it can withstand some water exposure.

Features Face to Face

Weight and Size

Weight and Size

The Sangean MMR-88 is the more compact, lightweight option, measuring only 5.98 x 2.71 x 3.3 inches and weighing 0.86 pounds. Compare this to the Midland ER310, which measures 8 x 2.4 x 3.4 inches and weighs 1 pound, and the Sangean is the winner of this category if you’re looking for extra portability.

Note that the Sangean also comes with an included hand strap for even easier carrying.

Water Resistance

While the Midland has no water resistance rating, the Sangean is IPX3 rated. This means it can withstand sprays of water, but it is not truly waterproof.

Although the Midland may hold up just fine to some water exposure, the Sangean wins this category due to its official water resistance rating.

Power Sources and Batteries

Power Sources and Batteries

Both radios are rechargeable via solar power, as they come with a built-in solar panel that charges the device in sunlight. If you don’t have a light source, you can charge them via the built-in hand crank. Alternatively, if you have access to an outlet or a portable charging device with USB cord, you can recharge the battery that way.

The main difference between these radios in power source is, firstly, the battery capacity.

The Midland ER310 features a 2600 mAh battery that provides around 32 hours of battery life, compared to the Sangean’s much smaller 850 mAh lithium battery that gives only five hours of life. Thus, the Midland will provide much longer functionality before needing to recharge and can more effectively charge other electronics.

Additionally, as a back-up option, the Midland can be powered by six AA batteries. This gives it a slight edge over the Sangean, which cannot utilize regular disposable batteries at all.

One positive aspect of the Sangean’s smaller battery is that it takes less time to fully charge, as it takes about 2 hours 50 minutes to charge the battery with a wall outlet fully. While its charge time is not stated, the Midland would likely take several hours to charge fully.

Overall, because it can be powered with disposable batteries and features a much higher battery capacity, the Midland ER310 is the clear winner in this category. Its larger battery not only gives the radio itself a longer life, but it also gives it more power to charge other devices, such as your phone, which may be vital in an emergency situation.

Usefulness in Emergency Situations

Usefulness in Emergency Situations

The included flashlight in both radios is essential for following your path in dark, dangerous situations or for flagging down emergency rescue teams.

The Sangean MMR-88 is equipped with an LED flashlight with four pre-set modes: SOS Morse code, high power for brighter light, low power for dim light, and a regular blinking setting. Similarly, the Midland ER310 has an SOS strobe beacon that flashes Morse code and separate high and low brightness settings.

While the Sangean, at high brightness, emits about 15 lumens of light, the Midland features a strong Cree LED that emits 130 lumens (1400 Lux) of light at its highest setting. This enables the Midland to give off a much brighter signal for rescue operations or to see in the dark.

Furthermore, the Midland is equipped with a high-frequency dog whistle that alerts rescue teams of your location. Because dogs have much better hearing and can hear at much higher frequencies than humans, this may be the difference between life and death in critical scenarios where the rescue dog is your last hope of being found.

To make up for the lack of an ultrasonic dog whistle, the Sangean features a loudspeaker with an emergency buzzer. This buzzer would be very useful in attracting attention in critical situations as well.

Both radios receive signals from all seven NOAA channels and are set up with weather alert functionality. The Sangean has 19 random preset stations and is a “public alert certified weather radio.”

Because of its additional alert feature (the dog whistle) and the much brighter flashlight, the Midland comes out on top in this category.

Much more battery power: The integrated lithium-ion battery of the Midland has a 2600 mAh capacity. Not only does this give the radio a longer life before needing to be charged, but it also enables you to more effectively charge your phone or other important devices with the included USB cable output.
