I like the fact that it's easy to replace the battery when needed.

I have used the APC battery back up (UPS) units for at least five years without any problems.

My computers are on 24 hours per day.  There have been a number of power interruptions both during the day and night.  The APC units have always operated properly.

It is for this reason, when adding additional work stations, the APC battery back up (UPS) units have been purchased for these work stations.

I purchased this as a battery backup for an air mattress.  It has enough power to provide a backup for at least 20 minutes.  It worked well for my purpose.  I did not have any issues with packaging, shipping or delivery.

I wanted a unit that I could plug in that included a battery backup and this seemed like the best option.

I really like that it has an extension on the plug so I can mount the unit on the wall.  Makes it much easier to check readings on it.

Seems well constructed.  Came with Duracell batteries which surprised me, as I'd expected really cheap useless ones.

So far, this little guy has been backing up my home PCs flawlessly.  It doesn't seem to run hot or draw much power.  I paired it with WD Red drives, so hopefully it will give me several years of service before needing to be replaced or upgraded.

It is a good UPS. It works. Wish the 550VA was the same price but this works for a smaller unit.

The Yubi Power YP250A USB Power Bank is a very compact, convenient to use, portable battery powered charging unit.  The dimensions are 3.7" long, by 0.85" square.  On one end of the unit, there is a USB port for output, and a mini-USB port, for recharging the battery bank.  Utilizing lithium ion batteries, the capacity of the device is 1500 mAh, with the standard output of 5 volts DC.  The YP250A is extremely easy to use, you turn it on, and then simply connect your USB powered device to it.

Controls consists of a power button, above which is a small silver colored bar, with red, blue, and green, LED indicator lights behind it.  When the unit is turned on, the blue LED coming on, indicates that power is available.  If the red LED comes on, the battery bank needs to be recharged.  When charging an external device, the blue light remains on until your device is fully charged.  After this, the blue LED turns off, and the green LED comes on.

A 9" long USB cord is provided for recharging the power bank, and can also be used for charging a device utilizing a mini-USB input.  When the battery bank is being recharged, the red LED stays on, until the batteries are fully charged, after which the green LED turns on.  A second accessory, is a carrying pouch.

Except for instructions printed on the back of the box, there is no documentation provided with the unit.  There is also a warning that when carried in a pocket or purse, the contacts of the USB ports, can accidentally be shorted out, by contact with metal objects.  Should the device fair to work, recharging is recommended to restore the unit to proper operation.

The YP250A is available in red, blue, silver, and black.  The unpainted brushed metal housing, appears that it might be easily marred, by incidental contact with other objects.  The provided pouch is rather large, but using it might be a good idea, as it would help prevent accidental shorts, and also protect the finish.

This product was provided to me for review purposes.  The best features are the compact size, simplicity of use, fairly quick recharge time, and relatively low cost.  Power capacity is adequate for those times when you need a little extra power, or on a short trip.  Just remember to bring any USB cords you will need.  I'm not sure how it would affect costs, but my suggestions to the folks at Yubi would be to go with a nice smooth painted enamel finish, add some brighter colors, and reduce the size of the pouch a bit.

Don't make the mistake of getting a UPS with lackluster capacity and without useful monitoring features, buy this one and have no regrets.

Quality battery at a very reasonable cost. The one I am replacing is 7 years old in a UPS. I made sure to replace it with the same make and size as the OEM unit

Meets my requirements for a compact battery charger.

Very nice unit that that does what it advertises. Unit must be on to charge so minus one star. Capacity is short by 1000mAh or so... Minus another star...

Item works great with our battery backup and computer.

The converter was just installed so it'll be 15 years before I can update you on the longevity of the product, but the remote unit is a nice addition to monitor the status of the converter and it runs very quietly. I also am a big fan of the multi-level smart charging feature. It's one of the main reasons I purchased this unit. The unit is also much more compact than the common unit manufacturers install in RV's.

Nice compact unit with a lot of power to charge portable devices.

The battery fit into the space fine.  The only thing missing in the description of the product was that it has the smaller terminal connections and not the F2 (1/4") as truly needed.  The plug was snug enough though to be securely attached.  Once installed plugged in the UPS for a day to charge the battery and then put it into use.

Great little unit if you need to house a hard drive from an old laptop.

I have some heavy duty power banks that could keep me going for a few days. But the reality is that they are larger and heavier and not ideal for a pocketbook or briefcase. This unit is.

It is a compact and nicely designed battery back-up with a bunch of great features. Soft edges, a clear 4 part display that shows how much juice is left, a built-in flashlight, and multiple plugs to fit your devices.

It also comes with a wall plug which a lot of smaller power banks are not including these days, so you can charge it at a wall or your computer. It also has a nice mess bag to keep everything inside (cables, power bank and all the plugs).

It was great for charging my phone and Kindle but, like most smaller power banks, does not charge my Samsung 10.1 tablet.

Tons of uses, never get stuck with a dead phone again!

I was provided a unit for evaluation and an honest review.
