This is a nice power brick that does the normal power brick stuff. I use it for camping and around the house when I am not near an outlet. It will charge my phone 2- 3 times, and added 40% to my jumbo iPad. I ’ m a fan of the quick USB- C quick charging. I discovered one hidden feature when camping, and this may be a happy accident. I didn ’ t see mention of this on the website…. When I was trying to plug my phone in while camping last time, I noticed that if I hit the button on the side of the power bank that it not only lit up the bars showing battery life, but it also lit up the plug charge holes. This is a really helpful feature when I don ’ t have a flashlight handy to figure out how to plug in at night. Whether this is clever design or a good accident, I like it.

[ Ampex was kind enough to send me this because I purchased a Tent, sleeping bag, sleeping pad, and backpack all from them. If I was able to do this over again I would. I would buy it myself because I love this power bank so much. I went on a multi day trip and was able to charge my phone once( didnt need to charge it more than 1 time at all) and still had a ton of power left in the bank. My favorite part about having this power bank is that I can charge my headlamp( not Ampex product) with it and can have peace of mind knowing that I can use my headlamp as much as I want and I 'll be able to have light my whole trip. I still use this product daily, not just up in the mountains!

The Rambler has quickly become an indispensable travel companion. I 've taken it camping, used it to power my laptop at the coffee shop and I have even flown across the country with it. I was a little bit worried that it would get flagged by TSA, but I have had no issues with it in my carry- on bag. I especially love that I do n't have to search for a power outlet at the terminal when I am flying. It is bigger than the 20K power bank that I had been using for a few years, but having a built- in AC outlet, wireless charging and more power capacity is worth it for me. I currently have an iPhone 12Pro that has an internal 2, 815mah battery and the Rambler provides nearly 4 phone recharges before I need to recharge it. However, I am usually using my phone at the same time so that is likely impacting my recharge rate to some extent. I was pleasantly surprised by the solid design, and I have really liked the digital display that shows the wattage being used and the battery life percentage remaining, so I do n't have to guess. All in all, I 've loved it and have even received a few compliments from fellow travelers.

Bought this radio just before hurricane Irma. it ran for 2 days before i got to charge it after the storm. it still had two charge bars left so it would have gone more. solar charged it after that. worked great but takes more time to charge. not a complaint. huge piece of mind when your house is shaking and you have no power to be able to get updates on the storm. we were able to get the weather update that told us that Irma had turned a little east and we were through the worst of the storm. we had no power for the next 9 days but we had all the local info we needed thanks to this radio. buy it and put it in your hurricane kit now.

5 Uncle Dave
I remember Midland radios from back in the hay- day of CB ’s, the 1970s. Always good quality and a good signal. I am a licensed Ham Radio Operator today and I am still impressed by the quality of workmanship and quality of signal. The ER- 310 has many great features but one stands out for me; Other “ emergency crank radios ” can only be charged by solar or crank… both taking a long time. The ER- 310 can also be charged with an included USB cable. This makes re- charging SO MUCH EASIER. I have bought 4 radios now; for myself and other Ham Radio friends. They all enjoy and appreciate these fine radios. Especially during Hurricane Season here in FLorida.

5 rjpftl
We ’ re very pleased with this radio. It performs exactly as advertised. I hope we never need to use it in a serious emergency, which here in Florida would be a major hurricane, and some occasional tornadoes, but I have confidence in it. A major issue here is power loss for extended periods, which has happened before. I like that it has multiple power options, in addition to plug- in AC. The solar, battery( both Li- ion and double- AA), plus hand crank sources should keep us connected. I also like 2 features I think are quite clever, but potentially important. One is the continuous SOS beacon. We ’ ve had hurricanes where flooding has marooned people onto their roofs, even into trees. This could attract rescue aircraft. Second is the dog whistle. We might not use that locally, but if we tried to evacuate with our car, and subsequently became blocked and stranded, perhaps had to abandon the car, search& rescue teams might find us. That ’s also where its self- contained portability is a plus. My only suggestion might be making the radio water resistant. Since heavy rain& flooding are typical with most of the weather threats we ’ ve faced here.

I bought this for a friend in Negril Jamaica as a birthday present... he has his own fruit stand biz across from my resort.. he's open from 9am til 6: 30pm& this radio plays all day long from his over night charge.. nice& clear audio too.. amazing little radio for sure..

As a collector of NOAA Weather Radios. I can say that this is one of the best weather radios in my collection. However, I ’ m giving it technically 4. 5 stars mainly because the add alerts function does not exist on this radio and the fact that the very loud siren can not be turned down( except with some clear tape which put it down to an acceptable volume). Aside from those things, this was well worth the money, and it includes all the features from the previous Midland Radios plus new ones such as the USB charging, backlight adjustment, unique mini- USB AC adapter, reception meter, and many more! We ’ ve had two days straight of severe weather and this radio has received all alerts even in touch- and- go reception from using distant transmitters. This radio is a perfect gift to yourself, a friend, or a family member for warnings of severe weather!

5 The Hawkins EAS
This is an amazing radio. Midland's best product yet!!! I have had this radio for about 2 months now. The reception is amazing. I can get a transmitter that is nearly about 100 miles. And I live in a very industrial town. This is top quality yet. And I have one good or bad thing that anyone would like. The alarm clock buzzer. It is the loudest buzzer I have ever heard. I woke up thinking there was a TOR issued. Anyways, Top quality, and TRULY AMAZING.

I have several Midland Weather Radios at home already and ordered a new one( Midland Radio- Deluxe NOAA Weather Radio) to take on the road while working out of state across the USA.

Frequently Asked Questions For Battery Backup

A battery backup is a device that provides temporary power to electrical devices during a power outage or when the main power source is unavailable. It typically contains rechargeable batteries that store energy, allowing for a seamless transition to backup power. These systems can vary in capacity and output, making them suitable for different applications, from powering small electronics to larger appliances.

When choosing a battery backup, consider factors such as capacity, output power, and the number of ports available for connecting devices. Additionally, look for features like portability, charging speed, and any built-in safety mechanisms to protect your devices. Understanding your power needs and usage scenarios will help you select the right model.

Battery backups can power a wide range of devices, including smartphones, laptops, small appliances, and even outdoor equipment. The specific devices you can power will depend on the backup's capacity and output specifications. It's important to check the power requirements of your devices to ensure compatibility.

The duration a battery backup can provide power depends on its capacity and the power consumption of the connected devices. Generally, a higher capacity battery will last longer, but the actual runtime will vary based on how much power your devices draw. It's helpful to calculate the total wattage of your devices to estimate how long the backup will last.

Yes, there are various types of battery backups designed for specific uses, such as portable power stations for outdoor activities, compact power banks for mobile devices, and larger systems for home use. Each type is tailored to meet different power needs and usage scenarios, so it's essential to choose one that aligns with your intended application.

Maintaining a battery backup system typically involves regular checks on the battery's charge level and ensuring it is kept in a cool, dry place. It's also important to follow the manufacturer's guidelines for charging and storage to prolong battery life. Periodically testing the backup system can help ensure it functions properly when needed.
