The only iPhone battery case with built-in topo maps
Starting @ $149
Topo Maps are inside the case.
Maps, so many maps. The TopoCharger holds gigabytes of outdoor maps without eating up
precious iPhone memory. The included Map Card comes pre-loaded with statewide topo maps.
Just pick the state of your choice. Then view full-color topo maps in 18 zoom levels (1:250K to
1:24K) down to 20-foot contours in most places. See public lands, parks, lake maps, and more.
Get another Map Card and swap between states too. The iPhone is now a Map Machine.
Boost your iPhone's battery.
More power means more fun. The internal 1460mAh lithium-polymer battery doubles the
battery life of the iPhone. The TopoCharger is re-charged with an included micro-USB cable
and a color-coded LED light indicates the case's charge status. Booyah!
TopoCharger works off-the-grid.
TopoCharger defies modern wisdom. The offline maps are
stored inside the slim 3-ounce case, so you don't need cell
and data signals to view them on your iPhone. Never see a
blank map screen again. Go far. Go explore. Get away from the grid.
TopoCharger comes with GPS powers.
Discover something new. With TopoCharger, you get a free
GPS app, Trimble Outdoors Navigator. The app taps into
the GPS chip built into your iPhone, so no phone signal is
needed. Seriously: Forgetaboutit. You have GPS power:
Mark points, collect routes, capture photos, and more.
Discover (or stay off) private lands.
Know before you step into the unknown. Customize your TopoCharger with private
land maps. We have the details on more than 167.2 million land plots in 39 states.
View the private land boundaries, assessor's parcel number and, when available,
the landowner's name. Problem solved.
Testers sing praises.
Top outdoor and tech journalists are charged up. "TopoCharger
converts an iPhone into an outdoor GPS," says Gizmag. The case has
also won three Best in Show awards. We're honored.
