Yes. Keep a charged Max 8.0 and its hub in the house, and you can keep phones and tablets running when the power goes out. It’s also a quiet way to charge USB devices at an off-grid homestead, in a cabin or in a tiny home.

Yes! That’s what the USB hub is for. One battery runs your trail camera during the season, then slides into the hub and goes along to the campsite, the boat, the deer blind or the ice shanty. Everybody’s phones, the tablet for the kids, headlamps and the laptop stay charged without a generator or a running truck. https://millertechenergy.com/product/slide-on-usb-charging-port-for-1128-trail-camera-battery-1128-usb/

No. It has DC barrel plug output for cameras and USB-A and USB-C ports through the hub. It’s built for USB gear and 12V-style camera power, not for household plug-in appliances. For bigger off-grid power, call our Support Team about Millertech’s larger batteries and inverters.

Up to eight on the Max 8.0 hub (four USB-A and four USB-C) and up to four on the Max 4.0 hub (two of each). That’s enough to keep the whole group’s phones charged at camp.

The battery, a battery charger, an adjustable mounting strap and three connector cables that fit most major trail camera brands (5.5mm x 2.1mm, 4.0mm x 1.7mm and 4.8mm x 1.7mm). The USB hub, security camera adapter, splitter and 6V converter are sold separately.

The Millertech app for iOS and Android shows:
• Remaining capacity, total capacity and amp hours
• Voltage and current
• Temperature
• Recharge cycle count
• Battery status and an error log
You can also give each battery a name, like “Trolling” or “Cranking.”

Fish finders and LED lighting, too. Fish finders need a cord sold separately.

It’s an add-on that slides onto your auxiliary battery and turns it into a USB power station. If it charges from a USB cord, you can power it from your Millertech battery. There’s one hub for each size, sold separately:
