The above are the 2 most commonly used by me to charge my smartphones : Energizer XP4001 and Yoobao YB602
Here are the details of these 2 battery chargers :
ENERGIZER XP4001 : 4000 mAh
Purchased at Singapore IT Fair for S$ 89 ( about RM 213 ): An expensive charger that is not really worth its price. In Malaysia the retail price is around RM 240
Tech Specs : Input : DC5V and Output : 1.0A ( 1 USB) , 0.5A ( 2 USB) ; CAPACITY – 4000 mAh
The XP4001 is a flat and rectangular battery (5.2 by 3.2 by .6 inches HWD ) that has great looks. Its unique features are those rubbery sides which are patterned recessed dots and nice to hold. The device has two USB ports and an AC adapter port on one side and two lights on top ( one to show charging mode and the other battery level left).
You need to press down the first top button to commence charging the smartphone. It will light up for a short while and shuts off after a few seconds. The first light runs when you’re charging the battery itself; it starts out red, but becomes green when the battery is full. The second light lets you check the battery’s status when you’re running it down, once more giving you either red or green depending on whether it’s running out of juice. The second light however ” broke down” and failed to work after a few days usage !!
There are two USB ports, meaning simultaneously you can charge 2 smartphones at the same time. However power output will be limited to max 0.5A each. Using just one USB port will gives you the max 1A power output.
Performance :
Charging time to full from near empty is about 4 hours
Charging most smartphones ( battery size about 1650-1750 mAh ) : Battery level increased by 25-26 % in 1 hour
The XP4001 requires an external, AC power adapter to charge it. It also comes with a velvet carrying case and two USB cables to connect it to your smartphone. The cables are short and don’t terminate in standard microUSB ends. Instead, you get six plug-in “tips” that can terminate in microUSB, miniUSB, Apple dock connectors or Nokia, Samsung, or LG older proprietary phone connectors.

YOOBAO YB602 : 4800 mAh
This is a much better external charger than the Energizer XP4001. It is easy to use . Just plug in and it will charge the smartphone without any need to press any additional buttons. This charger is compact size , rectangular in form and is thicker by 1 cm compared to the Energizer XP4001. I bought this online from http://www.lelong.com.my for RM 119 , about half the price compared with the XP4001. The 5 LED lights in front will display at anytime the charge level level in the charger – a very useful feature.
This charger also comes with a set of tips for commonly used smartphones

Buying Yoobao external chargers, one need to be extra careful as there are plenty fakes/imitations in the market. Do consult this website to identify the genuine from those imiatation types: http://www.yoobao.com/news.asp?id=134

YOOBAO YB 642 : 11200 mAh charger
This charger I used it to charge my Android tablets and ipad2 besides the smartphones. It has 2 USB ports – one at 1A and the other at 2A. The 2A output port is used to charge the tablets
I paid RM 230 for this and purchased it through http://www.lelong.com.my

Using the 11200mah yoobao unit.. Got it for RM299 here in Penang after reading your post on LYN about it, and I am happy with it. It even has the head for the Samsung Galaxy Tab.

Some other places offered much lower prices, even down to RM199. I decided to stick to a seller I trusted. No complaints, though, the powerbank has been very useful, a real lifesaver

I use the YB 4800 MAH charger for my tablet (Samsung GTab 7+ or 10.1) and it takes a while to charge. Usually keep it off while charging as it will charge faster. Thinking of getting a 11000 MAH one now.

I am using a Galaxy S2 G.
My battery can only last 9 hours. I don’t play games, only use it for work;
- calls (not more than 15mins total in 1 day)
- sms (a lot! most likely 30-50)
- internet (gmail, maybe 5x a day)
So I am quite disappointed in it;s battery life.
Could you help me make a decision or share some of your expertise?
I know you are quite an expert in phones through LowYat Forum.
I understand that there are 3 options; battery case, battery charger bank or an extra battery.
Battery case
- Can we use the phone while the case is on? Because usually when the phone is charging through the power socket, I can get a shock when I touch the phone so I wonder if the case will give the same problem since it’s also charging the phone.
- Can we charge the case using through a power socket or can it only be charged while it’s on the phone and connected to a usb port?
- If we have to charge it first externally to the wall socket, how long does it take to fully charge the case?
Battery charger bank
- Same problem as a battery case. Can we use the phone while the case is on? Because usually when the phone is charging through the power socket, I can get a shock when I touch the phone so I wonder if the case will give the same problem since it’s also charging the phone.
- Do we charge this power bank first?
Extra battery
- Do we get like a dock so that we can charge it externally or can the extra battery only be charged when it’s in the phone. if it is the latter, it will kinda defeat it’s purpose because the phone will have to be charged 6 hours a day then.
Thanks and Best Regards
