This review is from: FREMO P52 5200mAh Power Bank External Battery Charger for iPhone, iPad Air, mini, Galaxy S5, S4, Note, Galaxy Tab, Nexus, HTC One, One 2 (M8), PS Vita and other Smartphones and Tablets (made by SCUD)
Pros: This was able to charge my Droid Razr Maxx twice from about a half charge.
The aluminum construction gives this unit a real solid feel.
This charges my phone super fast. The app on my phone says it is charging at 1.3A, that is faster than the wall charger that came with my phone. My wall charger only charges my phone at 0.8A.
It says in the instructions that the battery bank will turn off when charging is complete. I think what they meant is that it will stop charging the device because mine didn't turn off, but it did stop fast charging my phone. It switch into a "trickle charge" type of mode to keep my phone at 100%, but not overcharge the phone. This behavior is just like a real charger, which I like. Though I'm not sure if this is a function of the battery bank or the phone, because even the cheapest of chargers does this, so I think this is actually built into the phone. Either way, I think this behavior is the best way to do it. I don't think I'd like this as much if it just charged my phone to 100% then turned off and let the phone die.
Cons: Instructions are extremely lacking. It tells you what the LED lights represent and how to hook things up, but doesn't mention what the power button does. I couldn't actually figure out what the power button does, it doesn't turn the unit off and the unit seems to power itself on when something is connected.
Mine had a large glob of glue coming out of the bottom between the aluminum and the plastic end caps. It was easily peeled off, but it was very unsightly and left a little residue behind.
It seems to take a really long time to charge the power bank. While it would charge my phone in about an hour, it took over two hours to charge the power bank back up. I think this is partially due to the fact that the power bank will only take 1.0A of power input.
Other Thoughts: I live in an area that has frequent power outages. I also use my phone for an alarm clock. Those two things have gotten me in trouble for oversleeping many times. I actually think this will be a useful. I plan to plug my phone into this battery bank overnight to charge, so even if the power goes out, my phone will still charge and be on in the morning. Then I'll charge the battery bank during the day while I'm at work.READ FULL REVIEW
Pros: This board overall is a great motherboard. ASRock and ASUS are the only two manufacturers that test their Z97 boards with Xeon processors, and I applaud them for that. This board officially supports Xeon processors, which is what I put in it.
And while the Xeon could not be overclocked, the board did offer some nice features to at least help improve performance with my Xeon. These basically allowed me to force my Xeon to run at the full boost clock speed at all times. This was nice to see.
The onboard audio is very good. I only had one other motherboard that had better sounding onboard audio, and that was my ASUS z97-Pro.
The color scheme is really good looking. It especially works if you are doing a build with AMD graphics cards.
The dual-BIOS socketed BIOS chips was a very nice feature. I've had BIOS flashes go wrong before, and it is nice to see the option to have a backup at all times.
This board is every inexpensive for what you get. It has pretty much all of the features of the higher end boards, including a decent VRM power design, and it is $30-60 cheaper than the more expensive motherboards. ASRock never stops amazing me with their quality and value!
Cons: This motherboard lost major points because of the BIOS issues I encountered.
The first issue is that the mouse does not work in the BIOS. When I enter the UEFI BIOS I see the mouse cursor in the middle of the screen, but it will not move. However, when I use my keyboard to navigate to certain areas where a pop-up dialog comes up, the mouse starts working and will continue to work until I reboot and go into the UEFI BIOS screen again. Also, if I unplug and plug the mouse back in, it will begin working in the BIOS as well. Since one of the reasons to use a UEFI BIOS screen is to have mouse support, this seems like a pretty big bug to overlook.
The next problem comes when I switched the SATA mode from ACHI to RAID to set up my SSDs and HDDs in their RAID arrays. When the screen comes up asking me to press Ctrl+I to configure the RAID arrays, the motherboard would not recognize my USB keyboard. No matter what port I had it plugged into, it simply would not allow me to enter the RAID configuration screen using a USB keyboard. I had to find a PS/2 keyboard to finally get in and configure my RAID arrays. I was just lucky that I had a PS/2 keyboard in my basement still, because I don't even think I'd be able to buy one locally at this point.
Finally, I though updating the BIOS might solve some of these issues. Long story short, it didn't, but updating the BIOS didn't work properly either. First I tried using the option to update the BIOS over the internet. I've used this feature on several other ASRock motherboard before without any issue. However, this time it would not work. Every time I tried it, the board would tell me there is an update, but when it tried to download the updated BIOS it would give a connection error. I tried about 5 times before giving up. So then I tried to load the BIOS on a flash drive an use the Instant Flash feature. NOPE! No matter what I did, I could not get the Instant Flash to recognize the BIOS file on my flash drive. It just keep saying "No Image File Detected". Finally, out of frustration I tried the Internet Flash once more before giving up complete, and finally it worked! Too bad it didn't solve any of the BIOS issues I am having...
Other Thoughts: I believe all my problems with this motherboard can be fixed with a BIOS update. This is the reason that I only took off a single egg. It seems that ASRock is working on pushing out BIOS updates for this board as well. ASRock as already released 2 BIOS updates in the last month since this board has been released. Hopefully they keep up with that trend and get the kinks totally worked out. If it wasn't for the fact that they've shown effort in trying to get BIOS issues worked out, I would have taken off 2 eggs for these issues.
I'd also like to touch on the Killer NIC E2200. I'll say it right now, it is nothing more than a marketing gimmick. It is nothing more than a Qualcomm Athero AR8161 NIC chip with slightly modified drivers to adjust the QoS to prioritize gaming. However, in the real world this makes absolutely no difference. In fact, I had to force load the original Qualcomm driver because the Killer E2200 driver would not work properly with Windows 2008 R2 that I was using on the system.
Overall, this is actually a very solid motherboard, and it really can't be beat for the price. This is the best value for a z97 motherboard I've seen.
Pros: Even though this drive is designed for use in Surveillance/DVR equipment, I'm actually using this drive as a storage drive as well as my drive that I record all my video game footage. It works perfectly for both tasks.
This drive offers a massive amount of space at a very reasonable price.
Speed wise, this drive is not the best, but it also is no slouch. I got average write speeds of ~125MB/s. Average read speeds were ~140MB/s.
This drive is only 5900RPM, so it uses very little power. But this leads to higher latencies.(See Cons)
The lower RPM also means this drive generates less heat, which makes it well suited for being used in either an external enclosure, or a DVR. The lower RPM also means the drive should last longer, the 1 Million Hour MTBF is evidence of this.
Cons: The biggest con I have with this drive is the latency. The average latency with HD Tune is 20ms write, and 22ms read. These are really high. I have other 5900RPM drives that have latancies of 13ms. However, since this drive is optimized for surveillance, which will have long sustained writes and not a lot of random reads/writes, I can understand the high latancies.
I was really worried when I saw the 1 Year warranty listed on Newegg, I actually couldn't believe it. So I checked with Seagate and this drive actually has a 3 year warranty. While that is better than 1 year, I actually expected this drive to have a 5 year warranty. Considering the MTBF and the fact that this drive is designed for businesses to use for surveillance, I don't think 5 years is unreasonable.
Other Thoughts: Newegg should really fix the listing for the Warranty of this drive. The 1 Year warranty listing is likely going to turn off a lot of buyers, and most won't research the actual warranty like I did.READ FULL REVIEW
