Pros: - Great Price/Watt Value Ratio when On-Sale.
- Compact Size for the Battery Size.
- GUI Controller Interface
- Line Filtering for Ethernet (See Cons)
- Line Filtering for RJ-6
- Line Filtering for Cable (See Cons)
- Outlet Spacing is Large Enough to allow multiple Power Adapters.
- Enough Reserve Capacity to power Routers or Modems for 1+ hours.
I own several of the 825 VA and 650 VA models which are distributed around the building to protect Routers, Access Points, Modems, Cable Boxes, HDTV's, Monitors, ADC boxes, and other smaller electronic devices from line voltage spikes and variations. They work excellent for that. The units are relatively compact (compared to other larger capacity UPS's which are for the servers) even though they are dense (high weight per volume). These units supply a constant line voltage to the electronic devices which they like. I get 100% uptime on the routers, modems, access points and other devices when connected to the UPS where I encountered random drop outs requiring device resets when they were just plugged into standard outlets.
Cons: - The line filtering for the Ethernet RJ-45 jack limits the bandwidth such that I cannot get better than T-100 (100 Mbps) through a T-1000 Gigabit connection.
- The Line filtering on the Cable limits the bandwidth such that I cannot get better than T-10 (10 Mbps) through the Cable line.
- The Line Filtering on the RJ-6 Phone/Modem/Fax jack limits the bandwidth to some small number such that it is unsusable.
- The control interface and software requires some study and investigation to actually be useful. It also does not have historical monitoring or per outlet monitoring for separate devices.
The limitations on bandwith, especially for the RJ-45 Ethernet connection, are severe enough to make them un-usable to me. This is unfortunate because this negates the capability of protection of the devices from lightening strikes or other voltage spikes through the data interfaces, not jus the line voltage spikes.
Other Thoughts: If you are just interested in protecting electronic devices from line voltage variations and want to make the voltage to the devices constant, these UPS's work great. Small, low power devices really benefit from the UPS. If you need 24/7 uptime on Routers and Modems, these are the way to go. They are small enough that you can have multiple units distributed around the office, or home to protect all of your small electronic devices. These 825 VA units have enough reserve capacity to power a small notebook, laptop, or tablet for several hours unless you are using a large monitor with them. They will power a larger desktop workstation or server for a few minutes to allow saving and shutdown without loss of critical information IF done quickly (within a few minutes).
If you are only using a low speed wired ethernet network (T-100 or slower), the line filtering may be of use to you. If your wired network is T-1000 Gigabit and you transfer lots of data like video files, the line filtering limitations make this feature unusable.
People who use PLA's (Power Line Adapters) to transfer data through the power lines instead of RJ-45 Ethernet cables. You will not be able to protect or use the PLA's with these. This is true for any line filtering device, not just the CyberPower UPS.
For home users who just want the battery backup and power line filtering, the CyberPower UPS is a great device. Just be aware of the limitations.
This review is from: Samsung S5 (G900) Wireless Healthy Activity Tracker (EI-AN900) Black
Pros: Appended Review (March 19, 2016):
- 1st unit purchased Had Connection Failures after 1 week use. 2nd unit Failed to connect/sync ever.
- Stay Away! It is a Total Waste of Your Time & Money!
- Inexpensive. After MIR it was only US$2.99
- Light Weight
- Comes with belt clip as well as wristband.
- Tracks sleep quality, steps, and Activity minutes.
- Easily synced to a Samsung Smartphone.
- As Accurate as a Samsung Phone but without the size/bulk limitations.
Cons: Edited: I purchased a second unit because the cost was Free after MIR and I thought I could get service on the first unit. The second one came with the exact same problem (failure to connect by Bluetooth to any Android device).
- Absolutely NO support from Newegg on returning defective product. They state clearly that they do not accept returns or replacements.
- Absolutely NO support from Samsung on return or replacement of defective devices. Tech Support (located in the Phillipines) does Not have any knowledge of this model. They state that they cannot support it and will not accept returns or replacements because they don't know anything about it.
- First Unit failed after 1 weeks use. Unit will not connect to any device by Blutooth.
- Second Unit was defective on Arrival! It would not sync or connect ever (after being fully charged).
- No return, No refund policy. This makes it a total ripoff.
- Requires a Mail In Rebate. This takes time, money, and effort.
Other Thoughts: The price makes the unit attractive and it would have been a fantastic deal... IF the unit worked. Failing after a week with no recourse is simply unacceptable. A Second Unit Purchased NEVER worked at all!
While the 1st. unit worked, my wife loved it since she didn't have to carry her phone around at work or when she exercised. It was easy to sync and the belt clip gave accurate counts of steps (not simply arm movement). The sleep quality feature was also nice since it is almost impossible to wear a Galaxy S5 phone to bed.
In conclusion, DO NOT BUY this Samsung S Health Activity Tracker. It is not supported at all. You are just throwing your money away! Do a search on this model and you will find many reviews on Youtube and other sites which state the exact same problems with connection/sync failure and lack of Samsung Support.
This review is from: ZeroLemon Y941 22800mAh JuiceBox External Battery Power Bank - Space Grey
Pros: -Sturdy Construction
- Highest mAh rating for the price (on sale) anywhere.
- Comes with power cable and mesh carrying bag.
- Power Switch has excellent positive feel.
- Indicator lights for remaining charge.
- Powers a Samsung Galaxy S5 for a week of VERY Heavy Usage and still maintains 50% Charge!
- 2 USB Power Outlet Ports rated for more than 2 amps. (Fast Charge of new SmartPhones on both ports)
Cons: - Large Size does not fit in women's pockets or fully in men's pockets (too long).
- Very dense. The weight does not lend itself to be easily carried in a women's purse comfortably. It isn't that comfortable to carry in a man's pant pocket. Certainly not in a man's suit jacket pocket.
- Unknown resistance to breakage when dropped (end caps are plastic).
- No way to turn off power indicator lights
The unit is compact for the amount of power capacity that it has. I took no eggs off because no other battery power bank has this capacity in a smaller size.
Other Thoughts: If you are in a location that is susceptible to power outages (example: NE USA last year) for more than a day, you need to consider one of these ZeroLemon Battery Power Bank's. As I stated in the Pros section, it has powered my Samsung Galaxy S5 for more than a week of very heavy usage on half a charge. This is excellent!
The indicator lights are nice to provide info on remaining charge left in the power bank. The front mounted on/off switch has a positive feel. The brushed and anodized aluminum case, the fit and finish, the weight and compactness of the unit, and the switch feel all contribute to an impression of excellent build quality.
I have had the unit for less than a month so I can not speak to the longevity of the batteries.
Overall, I recommend this ZeroLemon Power Bank to anyone who needs their portable electronic devices to work. Even with extended power outages.
