Well Built, Easy to Use, Solid Battery Charging System

Let me begin by saying that Ive only used my JNC660 once to jump start a V6 engine. It worked perfectly without a hitch. I purchased the JNC660 to replace the Schumacher Instant Power Plus (IPP) unit Ive used since 2008. The IPP really served me well over the years; however, I had to upgrade after replacing the battery three times due to an apparent problem with the over-charge monitoring circuitry. After doing much research, I chose to go with a JNC660 even though it does not have some features I found useful on the IPP unit. The first positives I find in the 660 is that it is well built and very compactit weighs a bit less than my old unit. Next, it is very simple to use with basic operational controls. The most significant feature I find with the 660 is its automatic charging system. This feature was a real deal breaker for some other brands of jump starters I evaluated during my research. My experience with replacing the IPP batteries made me realize how precious and important an automatic charging system really is. Another key feature I really like is that the 660s battery can be replaced by the user. The Clore user manual even provides instructions on how to perform the replacementvery nice deal.  Some of the units I looked at while researching did not support or provide any guidance on battery replacement. As with my old unit, I had to figure out how to change the batteryand this was no problem for me, as I am mechanically inclined.  And finally, the user instruction manual is top-shelfwell written. Now for the things about the 660 that MAY concern some people who use jump starters as a power source. First, consider that the 660s power rating is on the low side. Thus, it has wattage limitations as far as connecting power inverters to use devices that require AC voltage. The instruction manual indicates that power inverter capacity should not exceed 400Ws (350Ws recommended). I was curious about using my older model 400W (Continous) 800W (Peak) inverter with the 660 so I contacted Clore Tech Support. The Tech Support person confirmed that I should not use itthat I must use one with no more than a 400W Peak rating. Lastly, there is no ON/OFF switch. I personally don't see the need for one given that its primary purpose is for jumpstarting anyway. All in all, the JNC660 is a solid product that deserves serious consideration. It does not have a lot of bells and whistles but I accept ihat its simplicity serves the primary purpose. I cant much about the reliability but I should not have to worry about over-charging or frying any more batteries. I can only hope that the JNC 660 serves me well like my old jump starter.

I really like this one. I was afraid this would be bulky, but it compensates for its size by having the cable holder, which is surprisingly useful and saves a lot of wires tangling, or even worse - missing cable to make this thing at all useful.

Being brand new, it holds charge pretty well. The indicators are clear, and this is generally very easy to use. Even though battery technology is maturing, I think this particular one does what it's supposed to in an unobstrusive manner. Weight is relatively good, and it's easy to hold.

I searched Amazon extensively for a battery charger, looking for a unit that would be able to handle the primary DC power sources of my home: AA, AAA batteries. I ultimately decided upon the Eastshine universal battery charger.

The product appeared to be of obvious quality but it was far from cheap. It was fairly priced relative to its competitors, but, to make it an even better value, I signed up for subscribe and save to benefit from that discount.

Once I received the unit, and had the opportunity to test it first-hand, I knew that I had chosen right.

I selected this charger because of these especially appealing features:

It detects a battery's charge load/capacity and will charge the battery until maxed out and then automatically shuts-off charge to it.
It detects and digitally displays a battery's current charge, its charge capacity, and the estimated length of time before reaching full charge.
It can diagnose batteries that are bad, for ex: experiencing short-life syndrome.

Of course, there are units that charge more batteries all at once, but that's not how life works. A few batteries die here and there at a time.

Ideally, I would prefer a smaller, quality charger that I could walk away from and not have to worry about overcharging/overheating.

For that reason, I give this great little charger a solid 4.8-Stars!!!!  .8

I BOUGHT THE CTA MR-NB5L Mini Battery Charger Kit for Canon NB-5L Battery FROM Amazon fulfillment. Came neatly packaged did not look cheap like some. The unit is very sturdy tightly built slightly smaller footprint, and a little thicker than my Canon, not light and flimsy or rattling (a little unnerving) like others. Very well accessorized, Comes with neat compact car and euro adapters. Handles 100-240 Volt input and one of the best parts it is a 700mA output this is 100mA within my Canon charger and more than twice the other chargers on the net. This means it will charge the batteries in less than half the time of the others. The slandered Canon battery is 1080 mA if half used you need 540 mA charge (simplified), Battery needs 540/700 per Hr. charger = about  Hr. or 45 Min. On the other hand a 300mA charger, 540/300 will take = 1.8 Hrs or about 1Hr 45Min. In addition, The car charger is small enough to close most ashtrays on your vehicle, also a plus, seems to be a well thought out product.

  The only drawback I saw in this very well made/accessorized kit, was the LED is not very bright, maybe not a draw back if on your bedstand at night on a trip.

This is a very nice setup for the price.  You get a lot of flexibility in both charging and use with the included cables.  The panel itself will supply both 12V and USB power which is a nice touch, the battery charging module will allow you to charge USB devices, or you can remove the AA batteries for use in other equipment.  It includes a cig. light output socket so you can charge 12V directly from the panel if needed.  The battery charging module has some nice features and includes fairly good batteries (could be a bit higher capacity ,,but OK).  My only complaint so far is that when you are charging the battery module all the LED's light to show you the charge level and stay on during the charge.  Although the LED's don't draw much power this is a waste of some of the power the panel is putting out which would be better used to charge the batteries.  No need for the LEDS to stay on continuously IMHO.  Although it takes quite a while to get a full charge in my opinion this is a great survival tool which will get you emergency power when you need it the most, in other words when you have no other options...

This charger is beyond excellent.  One of the best built battery packs I have seen.  Well constructed.  Heavy but not too heavy. Perfect size for the cargo pocket in my shorts and the ports spaced apart on one side makes it very easy access to charge either one or two devices simultaneously.  The charge port on this battery charger is micro USB which is the same as you will find on most android and many other cell phones, tablets, hard drives, personal game machines, and other devices.  The battery pack comes with one small USB cable with standard USB ON one side and micro USB port on the other.  Used in one direction, you can charge the battery pack at night and simply flip the cable the other direction if you want to use the battery to charge your USB device.  This battery pack can simultaneously charge two devices and one of those could be a larger device such as a tablet. However, as there is only one USB cable included, you will need your own  extra cable if you want to charge a second device at the same time.  With 10,400 mAh power, there is plenty to recharge my phone several times during the day on the go.  It is nice to be able to come home at the end of the day and my phone and tablet are still at 100% power despite full use all day long.  The textured surface is also a very nice touch as well.

Solid feeling, easy to use automotive battery charger and emergency starter.  I bought mine a month ago and just used it for the first time to start my Chevy light truck in the cold New England winter.  With quick and simple setup, this unit has obvious pushbutton operation with convenient cord storage. I used the countdown start feature - 90 seconds later, the truck started right up.  Charger feels strongly built, but is light and easy to move around.  No sharp edges means you can set it anywhere when it's charging or starting your vehicle.  No on/off switch, so you just plug it in once the charger's battery clips are on the battery.  Nice device.

Glad I found this on Amazon--when I looked for Lipo chargers the only one I could find consistently was the Dynamite charger, which does not include the popular Dean's connector that my batteries are equipped with.

I am very pleased with this charger. It charges up to 6 amps, but since it still draws only 50w the utility of that is a bit limited. It works great, though, and charges my 5000 mAmp SMC battery in an hour. I am glad I located this, and I would buy it again.

This charger has decent instructions, though not outstanding; it is wise to have a basic understanding of Lipo battery charging principles if you're a beginner. The controls are fine and easy to use. See the description, but it does come with a variety of connector options that connect to its default Dean's plug. I believe (but cannot confirm) that it ships with more connector options than other chargers.

This is going to work out well for my needs. I bought this to charge a battery pack the requires 14-40 volts DC to fully charge. This item is constructed well with aluminum heat sink. easy to hook up just make sure you connect the input where it says too which is clearly marked on the bottom of unit. I would also highly recommend putting an inline fuse on both the input and output. Also this is cast aluminum so don't over tighten the mounting screws that you use or you may crack the heat sink.

This SROCKER i9 Portable Power Bank is priced comparably to others in its 8,000mAh capacity range, seems solidly yet thinly constructed (not overly bulky), and is of a very convenient size given its capacity. At about 5.25 inches long by 3.25 inches wide and about 3/8 inch thick, this backup battery is an easy carry in your brief case, laptop bag, purse or back-pack.

This unit comes with a micro-USB cable and we successfully tested, though we prefer to use the cables that came with our devices. It has four LED lights that provide an indication of charge level, letting you know how much juice is left in the battery. It arrived from the factory around 3/4 pre-charged and took a couple hours to complete the charge to 100%. Given its color and multi-color fading lights (embedded along 3/4 of the sides), our daughter decides this device was hers and she would recommend it to others.

This power bank weighs in at about 6.6 ounces, giving it a nice feel while still being very portable, and is constructed with an anodized aluminum.

Upon receiving the battery, we plugged the unit into our wall adapter (used my Samsung S3's wall adapter and the supplied micro USB cable) and topped off the charge. Operating this battery is fairly simple -- it has two output USB ports run by smart chip technology that directs up to 2.4A to each port as needed.

The storage capacity of this battery is 8,000mAh which is fairly substantial; great for charging the devices we have a couple times over, to help out in emergencies, and perfect for a long weekend away too. The charging times we experienced were consistently very strong, averaging about 1 percent per minute, or about 60% recharging per hour, from either port. Good performance that is much better than our wall chargers.

We tested this power bank with a Samsung S3 and an HTC Droid DNA. The battery pack did not get hot when being charged or when charging the devices.

The user manual is very basic and does not mention that warrant, but the Amazon listing notes that this power bank is covered by a 30-day money back guarantee and a 12 month warranty, so if an issue occurs within those periods I would return here to update the review and let you know what the issue was and how resolution was handled. I did receive this power bank gratis from the seller and have put it to use to objectively find out how well it performed. My statements here reflect that testing.

We found this power bank to be affordable, portable, and it does the job as described by the manufacturer. If you are looking for a battery pack of this color, 8,000 mAh capacity, size, style and excellent charge rate, for use as I have described above, then we recommend giving this SROCKER i9 Portable Power Bank a try based on our experience with it.

Recommended.

Go for it.

Excellent battery charger for the 18360 style batteries. Well lit display, with included charge time - voltage - amperage readings. Only have used it once so far and am very impressed with it's solid construction and design. Very high quality. Also included is a car charger cord. ( the cigarette style end kind ). Thanks EASTSHINE :)

This light is well-built and performs as advertised. The battery charger is easy to use and the AAA battery option is good for when the battery is charging or as a backup when you're away from a current source to use the charger.

Good: -Includes battery and USB charging which is impressive at this price point
-Solid build quality
-INCREDIBLE battery flexibilty.  Ran like a champ on protected, unprotected, flat top and button top 18650s, single or double 18350s and even disposable CR123s like advertised.
-Nice neutral tint (some "cree rainbow/tin shift" but thats not a fault of this light or Thrunite)
-Ramping interface is very simple for anyone to pick up and use with minimal understanding

Neutral: -Button is hard to find in the dark.  Wish it was recessed/countersunk like Zebralight and other brands, but others may prefer this type
-USB charging increases the length compared to other side-switch lights

Bad: -The ramping on this is too ssslllooowww in my opinion.  I have been spoiled by my BLF Q8 and Emisar D4 where its just slow enough to pick the output you want while allowing you to quickly reach it without sitting there waiting.  Turbo and moonlight are very quick to access on this light though which is great.
-Keeping the UI simple means very little customization.  I would love to have a way to change what some of the shortcuts do or change how fast the ramping is and/or where it starts and ends.

Overall, a GREAT deal for the price if you want a ramping light that doesn't require purchasing a battery or charger.  Keeping mine around the house for the roommates that don't seem to love setting up every aspect of a flashlight user interface the way I do.  Flashlight enthusiasts might be annoyed with some aspects but if I had to live with only this flashlight for a long time I don't think I'd really complain.  If I had to use one word to describe it, I'd say its "flexible".  Its flexible in battery type, size, output level thanks to the ramping and doesn't need a dedicated charger thanks to the USB port (+easy car or work charging, there's a mini USB charger damn near anywhere these days).

Would rate 4 and a half if Amazon would let me.

This powerpak battery pack is wonderful. It holds a charge for an
extensive period of time (I got at least 48 hours out of one charge to the
pack as well as recharging my phone multiple times in that time period.)
This battery pack is also nice because it allows for multiple devices to be
charged at the same time (cell phones and iPads/tablets). The battery pack
is very sturdy and stable and comes with a bag for carrying the device
around. The battery pack does have a little bit of weight to it, but that
is to be expected due to the nature of its use. The biggest complaint I
have about the device is that I do not feel that it is easy to tell whether
the device is on or not and whether or not it is fully charged and is
charging devices. According to the instructions, the different colored
lights (red, blue, and green) are the indicators of the charge, but I think
it would be more "user-friendly" if the lights always remained on and the
indication of the strength of the charge was made by the length of the
light (or bars). I believe that most devices indicate battery strength in
that manner, so that is what the consumer is used to when looking for
charge strength. Furthermore, I would turn on the battery pak and plug a
device in and after a while, the light would go off, but it seemed to still
be charging the device. So that seemed to be inconsistent with the LED
indicator instructions. All in all, the LED indicator issue was a minor
inconvenience and this device is reliable and easy to use.

Simple design and rechargeable; highly recommended purchase.

I bought the Battery Tender 2-Bank Battery Management System charger to replace a very old one that is close to end of life and mostly, for the capability of:
1. charging two batteries concurrently
2. overcharging protection

I was pleased with the weight of the Battery Tender, the compact size and the simple user's interface that shows the status of the charge.  It does the job effectively and the price is right.  I haven't had it long enough to make statement about its reliability except that it appears to be well made.  It is a plus that this charger can be used on a long list of different types of battery.  Please check the manufacturer's list to make sure that it fits the intended use.
