Review: A good deal - If you buy a TG-5, as just did, you need a charger, since the camera doesn't come with one. Olympus expects you to charge the battery in the camera with a USB cable, which means that you are using a capable and expensive camera to charge batteries! And the camera is out of action until there's juice in the battery. It's pretty awful to run out of power in just when things are getting good so it's always good practice to have at least one extra charged battery within reach. This set seems to be well made and it works. Apparently it will charge in a car, American wall sockets and even comes with an adapter for use in Europe. I can't speak for the quality of the batteries yet, but I will say that after market batteries have seldom let me down. This is a good deal for the price.

## Questions & Answers

**Q: Can I plug this charger into a typical wall jack?**
A: Note that this Amazon page covers 5 different products. The dual charger does NOT have the wall prongs for AC charging. Instead, it can be used with a powered USB port.

**Q: The batteries that come with it are not LI-92B batteries.  Will it still safely charge LI-92B batteries?**
A: The chargers for LI-90 and LI-92 batteries will interchange. However, the batteries looks like they interchange but they don't. The LI_90 battery is about 2-3 MM thicker and won't fit in my Ricoh / Olympus camera.

**Q: What if any is the difference between the LI-50B and 90B battery. I have 50B would they fit into the TG-2?**
A: Hiker.  I don't have a definitive answer but I recently bought some back-up batteries since the GPS eats up so much power.  I stuck with the 90B because I don't see any reason to try to guess if it will work as well. Plus the price is not expensive at all.  I got 2 batteries and a charger for about $ 30.

**Q: Am i the only one confused here?  the 90b is 1275 mah, the 92 is 1350 yet they are equivalent?  also the battery case shows 1500.  who do you believe?**
A: not a good battery life get something else

### ⭐⭐⭐⭐⭐ Great product

Everything I needed and works great

### ⭐⭐⭐⭐ Economical, High Capacity Solution
*by A***V on November 4, 2014*

BLUF: This is a great deal. It is much more economical than the OEM solution of approximately $90 for a spare battery and charger. The charger may look big in the pictures, but does have a surprising small form factor (3.75" L x 1.75"W x 1.5" T). Purchased this not knowing what to expect -- you get what you pay for type of thing. I was pleasantly surprised to find that the product was better than described. The capacity of the batteries was 2100-mAh, but were listed as 1500-mAh. This means more camera time/pictures...approximately 56% more than the OEM battery of 1350-mAh. If you trust the CIPA rating, which the Olympus TG-3 is rated at 330 pictures with the OEM battery, then the number of pictures taken with this higher capacity battery would be around 514. So, whatever the operating time is under your "standard conditions", these batteries would increase it by roughly 50%. For those of you unfamiliar with the physics of batteries: equate battery voltage to water pressure; capacity to the size of the water reservoir. More water is better, but if comes out at too high a pressure it can rupture the plumbing (electronic circuits in this case). Keeping within the manufacturers voltage rating (3.6V in this case) is definitely recommended, especially for sensitive electronics. I didn't buy this product because it included a screen protector. It's not bad, but for the long term, there are better options (e.g. Zagg). If you need one, it comes with a universal screen protector that must be cut-to-size. This product has two anomalies associated with it: 1) the battery label/markings are incorrect; 2) the charger will not charge the batteries unless you insert the battery first and then plug it in to an outlet. The first simply requires paying attention to the terminals on the end of the battery to ensure they're oriented correctly when inserting into the camera. For the camera, the orientation of the terminals are correct (+/- location), just not the "arrow" on the battery compared to that of the OEM -- the markings correspond to the charger, not the camera. The second is odd, but if you plug the charger in first, and then insert the battery, it gives a green light -- meaning it's not charging...in lieu of amber indicating it is charging.
