Can I use a non-Ricoh adapter for USB charging, providing it delivers 5V, 1000mA
1012023
I use both my Apple iPhone charger and my Kindle charger without any worries.

Can't answer your question directly but these extra batteries and charger from Amazon for about $22 work well: Wasabi Power Battery (2-Pack) and Charger for Ricoh DB-65 and Ricoh G700, G700SE, G600, GR, GR Digital, GR Digital II, GR Digital III, GR Digital IV, GX100, GX200, Caplio R3, R4, R5, R30

There are listings that show a power adapter suitable. I do not have one, but it is avaiiable.

I do not think so. The USB adapter is for transferring data only. Only DC battery. no 110 AC input.

Use any USB power adapter... either ac or automotive. RE: >> Cheap Generic << Even low cost "generic" devices today will get the USB voltage within USB specs and will be safe to use. Only the voltage matters... the amp/ma ratings simply show the chargers amp capability... if the USB device needs less current, the current flow will be less. I have used a wide variety of chargers, including 2.1 amp chargers, to charge my M55 for the past year.

It's not a charger per se - it is simply a passive adaptor. You could use it as a charger if you connect it to a source.

The standard is 500mA for USB 2.0 and 900mA for USB 3.0. Do the math, and you'll see that the power supply doesn't cut it for 24 USB 2.0 and 4 USB 3.0 ports. 24 x 500mA = 12A 4 x 900mA = 3.6A The power supply would need to be 15.6A at 5V. Since the power supply is only 4A at 5V, you're only going to be able to power four USB 3.0 devices (900mA x 4 = 3.6A) OR eight USB 2.0 devices (500mA x 8 = 4A). Perhaps Manhattan should do what Anker does and use a 12V adapter and whatever they do to undervolt/cut down their USB 3.0 9-port hub to 5V per port (that thing comes with a 12V, 5A power adapter! The brick is almost as big as most laptop power bricks!) Using the formula of Volts x Amps = Watts (5V x 15.6A = 78W), we can conclude that at 12V, only 6.5A would be needed (12V x 6.5A = 78W). It's a shame, though, as a 28-port USB hub is cool as all hell, but in practice, it doesn't work right unless you're using all self-powered devices (devices that have their own power adapters).

Read the USB wall pack's voltage input range. If it is ends up being only 110/120VAC 60Hz, then you can use another comparable output USB charger (amperage needs to be equal to or higher than the supplied pack).The USB side of things is not an issue, as 5VDC is the USB standard, so a wall adapter with USB charging ports on it will work just fine, so long as it is able to supply enough current (amps).The wall adapter is relatively inconsequential and equivalent ones made for your power grid are easily found if this one ends up not supporting your power grid.

this power supply *should* work with most devices requiring 5v power (such as usb hubs and external hard drives) and that have a 5v power receptacle that mates with the plug. however, you might want to watch the voltage as some units seem to have unstable voltage levels (one reviewer measured 6v from his unit) and i measured about 5.3v from mine, which seems a little high to me. any more than 5.1v and i'd be wary.

This operates using a standard USB cord that is separate from the cradle, not built-in. As long as you have a USB wall or Automotive adapter that can output 5V/1.5A minimum, you'll be ok.

Wish I could help but I bought this adapter for a USB Hub. I wouldn't know about it powering much else. Best of luck in finding what you need.

No...This is designed to be used with chargers. What you need to look for here is the Amp rating. At 1000 mA, this device will charge phones and small tablets etc. Devices such as compressors, mini refrigerators, car vacuums usually require more in the vicinity of 4000-8000 mA to function. This little guy (or gal), just does nothave the output to drive them.Check around on Amazon to find a more suitable one. Make sure you check the required Input Amps on the device you are interested in using, and ensure that the adapter you choose is rated higher.

I doubt it. The USB 3.0 spec only allows for 900ma when using data. A charge-only port can go as high as 1500ma. I don't expect this meter would measure much more than that. It should be stated that the 3.1 spec does allow for higher current, and voltage, but I don't think there are any devices supporting 3.1.

Here is another option for charginghttp://www.engadget.com/2009/02/20/wall-charger-takes-one-ac-outlet-provides-juice-for-five-usb-de/

Yes you do. This is the one. Generic Premium External Power Supply 5v 1A 2A (1000mA - 2000mA) AC/DC Adapter, Plug Tip: 1.35mm x 3.5mm x 7mm, for USB HUB and 2.5-inch HDD Enclosure

None... However, you must USE a separate power supply for the adapter. You must use at least 5 volts @ 2 Amps or 2000 mili-Amps or higher. It is use to power up what ever device that you going to use. Having a USB to power cord which came with the adapter is NOT good enough. My adapter plugs in deep into my laptop. I have problems with some USB devices because of the thickness of the USB end. It gets in the way of the laptop case. I use an extender to help resolve that problem.

Absolutely not. The amplifier needs 12 volts at 2 amps or more. A USB port supplies 5 Volts and only 1/10 to 1/2 amp at best. The new USB port standard (3.1 - yet to be released) will supply much higher current, but it's still only 5 volts. Besides, the plugs and sockets don't match up anyway.

I believe so; I plugged mine into a USB3.0 slot and charged batteries with it. The USB3.0 standard permits only 900mA continuous power.
