Pros: This item performs as stated. It is simple and it works.

Cons: None.

Overall Review: At least one person wrote "does not work on any usb with any hard drive even low wattage SSD" However, that makes no sense. a USB 3.0 port can supply up to 4.5 watts. Older USB 2.0 ports can supply up to 2.5 watts. A typical 2.5" SATA drive may require 1.6 watts, but during normal operations is closer to 1.3 watts. There is absolutely no problem with "powered by USB" in most cases. You should, of course, verify the rated power requirements of any device you intend to connect via this or any similar adapter cable.

Pros: PROS: Nice package; compact and lightweight.

Cons: CONS: I own 2 other battery packs very similar to this one, but different brand and lower rating (26,000 mAh, and 24,000 mAh). This one claims to be 50,000 mAh but loses its charge faster than either of the other ones with identical load. This one also takes longer to charge than the 2 with lower capacity. That is expected, except for their claim of "Recharges in 6 hours with a 2A adapter". It in fact takes almost 12 hours of charge time with a 2A adapter (tried 3 different adapters). The sales page claims "The Black Edition is able to provide 2.5 charges for Samsung Galaxy S6", but ran down almost completely after only 2 charges when the S6 still had 50% capacity. The other 2 lower capacity battery packs I mentioned, 26,000 mAh and 24,000 mAh, easily charge the S6 five times when the S6 is at 50% capacity.

Overall Review: I only give 2 stars, rather than 1, because of the low cost of the device. I think of it as having received a 16,350* mAh battery pack for a reasonable cost. If the sales page would have been honest in their claims, I would have given it a higher rating. I would not recommend this product because higher capacity products are available for just a few dollars more. *For reference: I measured capacity for these devices based upon the methods specified at the University of Michigan Energy Institute. That does not mean that the measurements were "perfect", but because I used identical setups for all 3 battery packs, the results provide a good relative baseline.

Pros: PROS: Good quality device, well built, not flimsy nor "cheap" in construction. The product arrived very well packed, and included a brief instruction pamphlet and a card with contact information for support from the manufacturer. The device performs as claimed, and does not even get hot when fully loaded. Others I've tried made me worry due to their thermal increase under load. I would recommend this product to anybody seeking a multiport charger.

Cons: CONS: Took a long time to arrive; 19 days. This was not the fault of the manufacturer, but the USPS and/or Newegg. USPS tracking showed only "Label created" until the day after delivery. Other items shipped via USPS generally have been taking a week or less; no idea why this one took so long. However, that's not a reflection upon the product quality.

Overall Review: SUMMARY: Excellent quality product. I would recommend this product to anybody seeking a multiport charger.

Pros: Good quality, perform as claimed.

Cons: None.

Overall Review: Over the past few years I have purchased over 50 of these drives; some for myself and others for customers. So far (as of January 2021) there have been zero problems with them. If you're wanting low-cost backup drives, this product is a good choice.

Pros: Ample memory and internal disc, smooth performance, beautiful display, almost no bloatware pre-installed, easy to set up.

Cons: Has McAfee trial version pre-installed. Has Norton Backup pre-installed. The power connector is a right-angle type, and it connects immediately beside the DVD tray. If the cable is not positioned toward the rear of the computer, the DVD tray can not open. It is not a critical flaw, but for anybody who does not pay attention to such things, there is the potential to damage the DVD tray.

Overall Review: I would not recommend this as a gaming machine, because the Intel Celeron 2957U is not a high-performance CPU. But for average work, browsing, email, photo editing and other general tasks, this computer is a very good value. Initial setup was particularly easy, partly because Acer pre-installs almost no bloatware. The computer was easy to secure, easy to configure a custom log-on screen, and easy to create media for a "emergency restore" if ever needed. If you need/want a notebook computer but can not spend a lot of money, I recommend this model.

Pros: Compact, ample storage space, great price.

Cons: None.

Overall Review: I've noticed many posts here comment about this device being slow. I've had this one since June 2012 and have used it on several different computers. One observation I have made is that it is somewhat slow on *some* systems, depending on what anti-virus/anti-malware application is installed. Also, on Windows Vista if I copy via Windows Explorer, the transfer rate is only about 6MB/second. But on the same machine, I see about 14MB/second when I use "Replicator" to copy files. Windows Explorer is a little faster on XP and on Windows 7, than on Vista......not sure why. On computers running Symantec, AVG or TrendMicro, file transfers are consistently MUCH slower than on similar systems running different AV products (Kaspersky, ESET, MSSE).

From time to time I see deals on refurbished items such as this one was. Glad I found it! This is a good quality UPS with enough battery power to maintain system uptime during brief power outages, and will allow ample time for a clean system shutdown if necessary.

I have put dozens of these in service during the past year; hundreds during the past several years. So far, not 1 problem. They are a reliable backup drive for ensuring that if any data is ever lost, recovery is quick and easy/
